0:00:02 > 0:00:06This programme contains some strong language
0:00:06 > 0:00:08We're living in a new age of invention.
0:00:08 > 0:00:12Brilliant brains are no longer just holed up in leading university labs
0:00:12 > 0:00:15or research facilities.
0:00:16 > 0:00:19Today inventors are coming together in technology hubs like this
0:00:19 > 0:00:23to design - to help improve people's lives.
0:00:23 > 0:00:26It's actually working. That's so cool!
0:00:26 > 0:00:28For this series, we've brought together
0:00:28 > 0:00:30seven of the UK's leading engineers, designers
0:00:30 > 0:00:32and computer programmers...
0:00:32 > 0:00:33Ta-da!
0:00:33 > 0:00:35I'm going to make myself the guinea pig.
0:00:35 > 0:00:38They will use cutting-edge science and technology
0:00:38 > 0:00:41to build life-changing solutions for people in desperate need.
0:00:41 > 0:00:44I don't know who to ask.
0:00:45 > 0:00:46Or where to go.
0:00:46 > 0:00:48In pain. Uncomfortable.
0:00:48 > 0:00:51From helping individuals who are seriously ill...
0:00:51 > 0:00:53- HE EXHALES - Whoa!
0:00:53 > 0:00:57..to solving issues affecting entire communities...
0:00:57 > 0:00:59Someone is either going to get seriously injured and can't get aid,
0:00:59 > 0:01:01or someone's going to die.
0:01:01 > 0:01:03They'll attempt to tackle major problems
0:01:03 > 0:01:06that have so far gone unsolved.
0:01:06 > 0:01:08I think I've created something really new
0:01:08 > 0:01:11and possibly revolutionary.
0:01:11 > 0:01:13The potential of this is massive.
0:01:13 > 0:01:16Fingers crossed...nothing cracks or explodes.
0:01:17 > 0:01:19This week, they'll try to give a voice
0:01:19 > 0:01:22to a paralysed man who can no longer speak.
0:01:22 > 0:01:27To enable him to have a bit of quality of life, I'd do anything.
0:01:27 > 0:01:29They'll attempt to give a teenage boy
0:01:29 > 0:01:32the chance to ride a bike for the very first time.
0:01:32 > 0:01:36This exercise has really illustrated how difficult it is.
0:01:36 > 0:01:39If you don't succeed, try, try, try again.
0:01:39 > 0:01:41And they'll design new technology
0:01:41 > 0:01:44they hope will stop a national crimewave.
0:01:44 > 0:01:46Nine of them dead, they got suffocated.
0:01:46 > 0:01:48The police don't stand a chance.
0:01:48 > 0:01:49They've got to catch them red-handed.
0:01:49 > 0:01:53If they succeed, they could change these people's lives
0:01:53 > 0:01:55and the lives of many more.
0:01:57 > 0:02:00Yeah!
0:02:00 > 0:02:01It's life-changing.
0:02:08 > 0:02:11Our team's base is in east London.
0:02:11 > 0:02:13It's one of a national network of maker spaces
0:02:13 > 0:02:15for a new generation of inventors.
0:02:17 > 0:02:18Crammed full of the latest technology,
0:02:18 > 0:02:21it's from here that our seven leading inventors
0:02:21 > 0:02:24will attempt to create fixes for people with nowhere else to turn.
0:02:24 > 0:02:26I'm excited about what we're going to learn.
0:02:26 > 0:02:28I can't wait to meet these people.
0:02:28 > 0:02:30The team includes a director from Microsoft,
0:02:30 > 0:02:33engineers who worked at Dyson's innovation labs,
0:02:33 > 0:02:36award-winning designers who've built everything from ambulances
0:02:36 > 0:02:38to earthquake centres.
0:02:38 > 0:02:40Let's get our sleeves rolled up and get stuck in.
0:02:40 > 0:02:42I'm Simon Reeve.
0:02:42 > 0:02:45Over the next nine months, I'll be working with this brilliant team.
0:02:47 > 0:02:48Today I'm in Peterborough,
0:02:48 > 0:02:51meeting the first person who's asked for the team's help.
0:02:52 > 0:02:55It's the first floor for Graham.
0:02:55 > 0:02:57This is Graham.
0:02:58 > 0:02:59Hello, Graham.
0:03:00 > 0:03:02Fist bump, I gather?
0:03:02 > 0:03:0655-year-old Graham Bullivant has partial locked-in syndrome
0:03:06 > 0:03:09and desperately needs a better way to communicate.
0:03:10 > 0:03:11There is no rush.
0:03:11 > 0:03:13It goes whatever speed you want. Don't rush for us.
0:03:15 > 0:03:19'In 2014, Graham, an engineer and family man,
0:03:19 > 0:03:21'suffered a massive stroke.
0:03:21 > 0:03:24'He now only has limited movement of his head and left arm.'
0:03:28 > 0:03:30"In pain all the time.
0:03:30 > 0:03:32"I'm sure people forget."
0:03:33 > 0:03:36His wife Zoe has been at his hospital bedside
0:03:36 > 0:03:38every day for nearly two years.
0:03:41 > 0:03:43Graham's brain works perfectly.
0:03:44 > 0:03:46"I am normal inside."
0:03:48 > 0:03:51"If Zoe's with me, I can face anything.
0:03:51 > 0:03:52"I get frustrated."
0:03:53 > 0:03:55I bet you do.
0:03:57 > 0:04:00And technology must be a bit frustrating, as well.
0:04:00 > 0:04:04This strikes me as being a hell of a lot better than nothing,
0:04:04 > 0:04:09but a really inadequate form of communication.
0:04:12 > 0:04:15It takes Graham more than three minutes to write a sentence
0:04:15 > 0:04:17it would take just seconds to say.
0:04:17 > 0:04:20I watch and wait and then read out what he's tapped.
0:04:22 > 0:04:24"It's too slow.
0:04:24 > 0:04:27"I can see everyone watching and reading
0:04:27 > 0:04:29"out of the corner of my eyes."
0:04:31 > 0:04:34And I'm wanting to say the words and break the silence,
0:04:34 > 0:04:36while you're tapping away.
0:04:36 > 0:04:38Must be incredibly frustrating for somebody
0:04:38 > 0:04:42who is very used to conversing, talking, chatting.
0:04:44 > 0:04:45The stylus I invented,
0:04:45 > 0:04:48because we've bought so many stylus for Graham to try,
0:04:48 > 0:04:51they're either too heavy or too short.
0:04:53 > 0:04:55After an hour of writing, Graham is exhausted.
0:04:55 > 0:04:57So we leave him to rest.
0:04:57 > 0:04:58Happy with that?
0:04:58 > 0:05:01Can you face talking about what life was like before it happened?
0:05:03 > 0:05:05Before? Oh, brill.
0:05:05 > 0:05:07Oh, my God. Fantastic.
0:05:07 > 0:05:09Every day was a blessing.
0:05:09 > 0:05:13You were married, you've been married for how long?
0:05:13 > 0:05:16Over 30 years. Way over 30 years.
0:05:16 > 0:05:18I was spoilt, really.
0:05:18 > 0:05:19He did everything for me.
0:05:19 > 0:05:23Have nice times, have holidays, he took all that pressure.
0:05:25 > 0:05:26And now it's my turn.
0:05:26 > 0:05:31And, my God, it's come as a big shock.
0:05:31 > 0:05:33When was the last time you actually heard his voice?
0:05:37 > 0:05:3914 months ago.
0:05:39 > 0:05:44When Graham lost his voice and I said to everybody,
0:05:44 > 0:05:47one of the things I said to all my friends and family,
0:05:47 > 0:05:50"Get a recording of your husband or boyfriend."
0:05:50 > 0:05:52Because, my God, did I miss that.
0:05:52 > 0:05:55That, "Goodnight, I love you."
0:05:55 > 0:05:57That was horrendous!
0:05:57 > 0:05:59Not having his voice.
0:06:00 > 0:06:02So I asked everybody, "Have you got a video?"
0:06:03 > 0:06:04Nothing.
0:06:05 > 0:06:07Nothing.
0:06:07 > 0:06:09I'll do anything for Graham.
0:06:09 > 0:06:11Now I've got to. I've got to.
0:06:11 > 0:06:14To enable him to have a bit of quality of life.
0:06:18 > 0:06:20Back at the inventors' hub in London,
0:06:20 > 0:06:22we talk through Graham's case.
0:06:24 > 0:06:27What do we think, at the moment, Graham wants?
0:06:27 > 0:06:29He wants to be able to communicate like he used to.
0:06:29 > 0:06:33He's got to tap it all out and it's so frustrating.
0:06:33 > 0:06:34Yeah, absolutely.
0:06:34 > 0:06:36When you're hanging out with your family,
0:06:36 > 0:06:39you want to express yourself emotionally and quickly.
0:06:39 > 0:06:42It's what makes us us.
0:06:42 > 0:06:46With these devices, they don't have an emphasis on,
0:06:46 > 0:06:47"I would like to be sarcastic."
0:06:47 > 0:06:51So that's something that we could, you know, help with.
0:06:51 > 0:06:54Try and figure out a way to get digital voice to sound sarcastic.
0:06:54 > 0:06:58It's something very profound that we're discussing, really, isn't it?
0:06:58 > 0:07:01It's not just giving him a new voice.
0:07:01 > 0:07:03In a way, it's giving him his old voice back.
0:07:03 > 0:07:07Yusuf Muhammad is an award-winning industrial designer
0:07:07 > 0:07:09who's worked extensively with the NHS.
0:07:10 > 0:07:12Today, he's taking me to look for alternatives
0:07:12 > 0:07:14for Graham's stylus pen and iPad.
0:07:17 > 0:07:21We meet Gary Derwent, an expert in assisted technologies.
0:07:21 > 0:07:24So we're just seeing that the system is picking up your eyes.
0:07:24 > 0:07:26He's going to demonstrate a system called Eye Gaze.
0:07:27 > 0:07:28Stable signal.
0:07:28 > 0:07:30- ARTIFICIAL VOICE:- W, E...
0:07:30 > 0:07:32Get ready to watch the orange circle.
0:07:33 > 0:07:36This is the jewel in the crown of communication aids,
0:07:36 > 0:07:39where an infrared camera allows you to control the system
0:07:39 > 0:07:41with your eyes alone.
0:07:41 > 0:07:44It's taking about 25 pictures a second of your eyes
0:07:44 > 0:07:47to differentiate the centre of your pupil
0:07:47 > 0:07:50and what they call the glint in your eye.
0:07:50 > 0:07:52When your eyes move, the glint stays in the same place,
0:07:52 > 0:07:54but the centre of your pupil moves.
0:07:54 > 0:07:56- It's looking for the glint in my eye?- It is.
0:07:56 > 0:07:58Brilliant! I love it.
0:07:58 > 0:08:00You select letters or words
0:08:00 > 0:08:02by letting your gaze rest on them for a moment.
0:08:02 > 0:08:03- ARTIFICIAL VOICE:- Hi...
0:08:06 > 0:08:07..there,
0:08:07 > 0:08:09how...
0:08:09 > 0:08:10are...
0:08:10 > 0:08:12And it uses an artificial voice,
0:08:12 > 0:08:15letting the user join in the conversation.
0:08:15 > 0:08:17- VOICE:- Hi there, how are you doing?
0:08:17 > 0:08:21It feels like I'm controlling the device with my mind.
0:08:21 > 0:08:24What extraordinary technology.
0:08:24 > 0:08:27- VOICE:- Hi, Simon, I'm doing well. I am writing with my eyes.
0:08:28 > 0:08:29The Eye Gaze could be the basis
0:08:29 > 0:08:31for a new communication system for Graham.
0:08:31 > 0:08:35But Yusuf doesn't think it will solve all of his problems.
0:08:36 > 0:08:38Fatigue is such a big, big thing.
0:08:38 > 0:08:43And I can tell, from just trying the system, that maintaining your gaze,
0:08:43 > 0:08:47I'm sure after a while it's going to be...quite laborious.
0:08:47 > 0:08:49So maybe he could use the pen from time to time,
0:08:49 > 0:08:51or he could use a switch controller.
0:08:54 > 0:08:57The next step is for Gary to meet Graham and assess him.
0:08:57 > 0:09:00So we're just going to do some calibration.
0:09:00 > 0:09:02These are the Eye Gaze cameras here at the bottom.
0:09:02 > 0:09:04There's going to be a dot that will appear on the screen
0:09:04 > 0:09:06and it'll move around.
0:09:06 > 0:09:08So your job is just to look at the dot and follow it.
0:09:10 > 0:09:13Are you finding that the dot is following your eye?
0:09:13 > 0:09:17No, it's not picking up exactly where you're looking at. No.
0:09:18 > 0:09:20Nerve damage, caused by the stroke,
0:09:20 > 0:09:23has affected Graham's eyes and pupils.
0:09:23 > 0:09:26So the camera is struggling to follow his gaze.
0:09:28 > 0:09:30Looking at what we've just witnessed...
0:09:31 > 0:09:32..might be the wrong route.
0:09:32 > 0:09:35So if Eye Gaze isn't the thing, that's fine.
0:09:35 > 0:09:37You know, it isn't right for everybody.
0:09:38 > 0:09:42I'm really pleased that you've come, so you can see how we're struggling.
0:09:42 > 0:09:45But obviously, if that's not the right angle to go down,
0:09:45 > 0:09:48- we'll try something else. I'm not giving up.- Yes.
0:09:49 > 0:09:51It's hugely disappointing,
0:09:51 > 0:09:54the Eye Gaze system doesn't work for Graham.
0:09:54 > 0:09:56Another solution has to be found.
0:10:02 > 0:10:04Back at the inventors' hub,
0:10:04 > 0:10:07the team are getting ready for their next challenge -
0:10:07 > 0:10:10to build a bike for Oscar, a disabled teenager.
0:10:10 > 0:10:12Yusuf will lead the case.
0:10:17 > 0:10:20Why did you want to get involved with this particular fix?
0:10:20 > 0:10:24Well, I mean, I love bikes, I'm really passionate about cycling
0:10:24 > 0:10:26and I think it's the kind of extra freedom it gives you.
0:10:26 > 0:10:28We used to cycle to and from the park,
0:10:28 > 0:10:31the wind in my hair - when I had hair!
0:10:31 > 0:10:34And just the independence
0:10:34 > 0:10:38of being able to explore your local area is very cool.
0:10:38 > 0:10:42You sound like the right man for this fix, Yusuf.
0:10:42 > 0:10:44I hope so. I hope so.
0:10:45 > 0:10:48We're in the West Midlands to meet Oscar,
0:10:48 > 0:10:51who seems to be a whizz in the kitchen.
0:10:51 > 0:10:52He puts us to work.
0:10:52 > 0:10:54Chop some mushrooms, maybe?
0:10:54 > 0:10:56I think you'll find that's my job!
0:10:56 > 0:10:58We've been here at least two minutes and we haven't had a cup of tea.
0:10:58 > 0:10:59What are you like?!
0:11:01 > 0:11:03Are you a keen cooker, Oscar?
0:11:03 > 0:11:05- Yeah.- What do you like about it?
0:11:06 > 0:11:09- The eating, or the...? - Cooking.
0:11:10 > 0:11:12Oscar has Moebius syndrome,
0:11:12 > 0:11:16a rare genetic condition which means he was born with no hands or feet.
0:11:17 > 0:11:21I can do the same as everyone,
0:11:21 > 0:11:24- but it would, like, take me a little bit longer.- Right.
0:11:25 > 0:11:28But there's something his friends can do that Oscar can't.
0:11:28 > 0:11:31And that's ride a bike.
0:11:31 > 0:11:35You've got two different prosthetics on your lower legs, haven't you?
0:11:35 > 0:11:36Yeah.
0:11:36 > 0:11:38And obviously, that's going to have an impact
0:11:38 > 0:11:41on how Yusuf creates the cycle for you.
0:11:41 > 0:11:42Mm.
0:11:42 > 0:11:44Are you going to perch in?
0:11:44 > 0:11:47'I learn more about Oscar's condition from his mum, Lisa.'
0:11:47 > 0:11:50So he's got heels on both.
0:11:50 > 0:11:52- Yeah.- And ankle joints.
0:11:52 > 0:11:57So he's got sort of a third to a half a foot on this side.
0:11:57 > 0:11:59Yeah.
0:12:00 > 0:12:02- What did he say? - Can he have a drink?
0:12:04 > 0:12:06He's off!
0:12:06 > 0:12:07He's such a lad.
0:12:07 > 0:12:10He's just about to become a teenager.
0:12:10 > 0:12:11Oh, yes.
0:12:12 > 0:12:15And for teenage boys, bikes aren't just about getting around.
0:12:15 > 0:12:17They're part of growing up.
0:12:17 > 0:12:20Without a bike, Oscar's being left behind.
0:12:20 > 0:12:24It's just kids their age, however thoughtful they are,
0:12:24 > 0:12:26- at some point they're going to want to cycle away.- Yeah.
0:12:26 > 0:12:29And then he's left standing there on his own.
0:12:29 > 0:12:32It's impossible for Oscar to ride a standard bike
0:12:32 > 0:12:34because he has no hands to grip the handlebars.
0:12:36 > 0:12:39Yusuf needs to come up with a custom alternative.
0:12:40 > 0:12:44We've come to Oscar's school to get a better idea of what he wants.
0:12:46 > 0:12:48Oscar, which handlebars do you prefer?
0:12:48 > 0:12:50These.
0:12:51 > 0:12:53- Seat?- This one. I want that one.
0:12:53 > 0:12:55Oh...
0:12:55 > 0:12:57- Yeah, that one goes.- Yeah?
0:12:57 > 0:12:59- Yeah.- What bikes are cool at the moment?
0:12:59 > 0:13:01BMX.
0:13:01 > 0:13:04- So BMXs are cool and that's what you would like?- Yeah.
0:13:04 > 0:13:09You think he'd much prefer a sort of a standard bike. Why was that?
0:13:09 > 0:13:10Because all his life
0:13:10 > 0:13:13he just didn't want to be known as different, really.
0:13:13 > 0:13:14He just wants to fit in.
0:13:14 > 0:13:19What is the most important thing to you about a bike?
0:13:19 > 0:13:22Make it look like as normal as possible.
0:13:23 > 0:13:25- Yeah.- I understand.
0:13:27 > 0:13:30Back at the hub in London, the team are discussing the challenge.
0:13:31 > 0:13:33- YUSUF:- Well, Oscar's never ridden a bike before.
0:13:33 > 0:13:36Really just depends on how he takes to it.
0:13:36 > 0:13:38Isn't this a really tricky one?
0:13:38 > 0:13:39It's really, really tricky.
0:13:39 > 0:13:44If we're trying to engineer something which has two wheels,
0:13:44 > 0:13:45that's obviously a real challenge.
0:13:45 > 0:13:47If he falls off, he could get quite hurt.
0:13:47 > 0:13:48We need to think about it like,
0:13:48 > 0:13:52"Would I be OK with this guy falling off a bike that I built?"
0:13:52 > 0:13:54There's a lot of downsides to making this thing.
0:13:54 > 0:13:57I don't know, I guess if you're going to graze your knees
0:13:57 > 0:13:58and fall off bikes,
0:13:58 > 0:14:00you know, this is the best age to do it.
0:14:00 > 0:14:04If you give him the opportunity to cycle,
0:14:04 > 0:14:08he will fall off, certainly, but he will fly, as well.
0:14:08 > 0:14:11And that will change his life, I think.
0:14:12 > 0:14:15Knowing the risks, Yusuf has come up with a plan.
0:14:16 > 0:14:18So I have...
0:14:18 > 0:14:22ordered myself an adult BMX.
0:14:22 > 0:14:24I'm going to make myself the guinea pig,
0:14:24 > 0:14:26try out a couple of these things,
0:14:26 > 0:14:29so I can have an understanding of what's going to work for Oscar.
0:14:32 > 0:14:33I mean, how is he going to steer?
0:14:33 > 0:14:36I have to consider how he's going to brake.
0:14:36 > 0:14:39So what we have here is a coaster brake,
0:14:39 > 0:14:41right there in the centre of the wheel.
0:14:41 > 0:14:45All Oscar has to do is backpedal
0:14:45 > 0:14:48and the bike will brake, hands-free.
0:14:49 > 0:14:51It's down to the park to try out his first prototype.
0:14:55 > 0:14:56Pretty easy.
0:14:56 > 0:14:59You can kind of screech to a halt.
0:14:59 > 0:15:02It works fine, but it doesn't have enough stopping power.
0:15:02 > 0:15:05Oscar will need a brake on the front wheel as well.
0:15:07 > 0:15:08I've designed a new brake position.
0:15:08 > 0:15:10Rather than pull the levers,
0:15:10 > 0:15:14I've reversed the brake position so that Oscar,
0:15:14 > 0:15:17all he has to do is push down with his forearms
0:15:17 > 0:15:19and he can activate the brakes.
0:15:20 > 0:15:23Back in the park, the front brake is proving to be a problem.
0:15:24 > 0:15:27You see now... You see, I can do it now.
0:15:27 > 0:15:29Now I can use the brake.
0:15:29 > 0:15:32Now I can use that brake and feel fine.
0:15:32 > 0:15:33But as soon as I'm standing up...
0:15:34 > 0:15:36..I've got no bloody chance. So...
0:15:36 > 0:15:38Whoa...!
0:15:38 > 0:15:42BMXs aren't really designed to be ridden sitting down.
0:15:42 > 0:15:45As soon as he operates the brake standing up...
0:15:45 > 0:15:46Jesus!
0:15:46 > 0:15:48..Yusuf loses his balance.
0:15:53 > 0:15:58I think this exercise has really illustrated how difficult it is.
0:15:58 > 0:16:00On a BMX like this it's not going to happen.
0:16:02 > 0:16:04- It's not going to work? - No.
0:16:04 > 0:16:07Adapting an off-the-shelf bike won't work.
0:16:07 > 0:16:10Yusuf will have to build a completely new bike
0:16:10 > 0:16:12from the bottom up.
0:16:18 > 0:16:21The team are trying to design a way for Graham to communicate.
0:16:22 > 0:16:25Ruby Steel is now leading the effort to find a solution.
0:16:25 > 0:16:31What's the absolute minimum effort required to make a control happen?
0:16:31 > 0:16:33She's a top design strategist.
0:16:34 > 0:16:37Through in-depth research into Graham and his condition,
0:16:37 > 0:16:40she'll decide what path the team will take.
0:16:40 > 0:16:41It's like driving a car.
0:16:41 > 0:16:44Like, you know, you use, like, your hands and you use your feet,
0:16:44 > 0:16:49so you're not putting all the emphasis on just one movement.
0:16:49 > 0:16:52After weeks of discussions and thousands of Post-it notes,
0:16:52 > 0:16:57the team decide to build Graham his own bespoke communication system.
0:16:58 > 0:17:01They are calling it the Reaction Pad.
0:17:01 > 0:17:07The Reaction Pad is about giving Graham back his presence in a room.
0:17:07 > 0:17:10The really tragic and most frustrating thing
0:17:10 > 0:17:12for Graham at the moment
0:17:12 > 0:17:17is that people are treating him like he's brain-dead when he's not.
0:17:18 > 0:17:22The key thing is that he can say just a quick statement
0:17:22 > 0:17:26whenever the urge comes across.
0:17:26 > 0:17:28So it's just really key phrases
0:17:28 > 0:17:32that will allow him to be part of a conversation
0:17:32 > 0:17:34in a way that he just can't at the moment.
0:17:35 > 0:17:38Ruby's in Peterborough to discuss the idea with Graham.
0:17:38 > 0:17:41Hi, it's good to see you. Hi, Graham. Hi, Zoe.
0:17:41 > 0:17:43This is Ross.
0:17:43 > 0:17:47I'm going to ask another member of the design team...
0:17:47 > 0:17:49Ross Atkin is a skilled designer and engineer
0:17:49 > 0:17:53who specialises in developing technology for disabled people.
0:17:53 > 0:17:57What we're proposing is an app that runs on the iPad.
0:17:57 > 0:17:59We're sort of calling it the Reaction Pad at the moment
0:17:59 > 0:18:04and it's, in essence, going to be a tablet to say things quickly.
0:18:04 > 0:18:07Their idea is for Graham to communicate
0:18:07 > 0:18:10using preloaded words and phrases.
0:18:10 > 0:18:12When you pick up the tablet, the app or whatever,
0:18:12 > 0:18:13this is the first screen you see.
0:18:13 > 0:18:18"Help" in the middle, as being the most important thing.
0:18:18 > 0:18:19When Graham pushes "help",
0:18:19 > 0:18:22he'll be taken to another screen that contains different commands.
0:18:23 > 0:18:26"In pain, uncomfortable, thirsty..."
0:18:26 > 0:18:29The app will contain buttons for quick statements.
0:18:29 > 0:18:32Things like, "Please, thank you..."
0:18:32 > 0:18:34Buttons for fast questions.
0:18:34 > 0:18:35"What, why, how?"
0:18:35 > 0:18:38And buttons to get people's attention.
0:18:38 > 0:18:41"Excuse me? Oi! Talk to me."
0:18:41 > 0:18:45The device will speak for Graham using an automated voice.
0:18:45 > 0:18:46One of the things we were trying to explore
0:18:46 > 0:18:49is what we could do that would be
0:18:49 > 0:18:53a sort of replacement of the robot voice.
0:18:53 > 0:18:55They don't tend to be very expressive
0:18:55 > 0:18:57and they don't tend to have a lot of emotion.
0:18:57 > 0:19:01We were interested in the idea of using clips
0:19:01 > 0:19:05from films and TV and cartoons.
0:19:05 > 0:19:07Good? Or scrap?
0:19:08 > 0:19:09- Good.- Good.
0:19:09 > 0:19:11- ZOE:- He's smiling like a Cheshire cat!
0:19:13 > 0:19:17And Ross thinks he can improve on Zoe's home-made stylus.
0:19:18 > 0:19:21We know that you get tired operating a stylus
0:19:21 > 0:19:24and so we're quite interested in
0:19:24 > 0:19:26things that might work better than the stylus.
0:19:26 > 0:19:29We could make you a thing that was just on a bit of cardboard
0:19:29 > 0:19:31or a very, very thin and light
0:19:31 > 0:19:34and it could have little touchpads, basically, printed on it,
0:19:34 > 0:19:36so that you could touch them with your fingers or with the stylus.
0:19:37 > 0:19:39OK.
0:19:39 > 0:19:41Thank you, Graham.
0:19:41 > 0:19:43- See you next week. - Yeah, take care.
0:19:45 > 0:19:49- ZOE:- "Have a drink for me."
0:19:49 > 0:19:52- All right. - Can definitely take care of that!
0:19:52 > 0:19:54- Can definitely do that. - Thanks, Graham.- Thank you, Graham.
0:19:54 > 0:19:56Thanks, guys. Nice meeting you.
0:20:02 > 0:20:05Yusuf is heading back to the West Midlands.
0:20:05 > 0:20:09The first BMX he adapted wouldn't work for Oscar,
0:20:09 > 0:20:12so he's decided to come up with an entirely new design.
0:20:12 > 0:20:16Just going to off-load so we can do some different exercises today.
0:20:17 > 0:20:20The first thing we can see is the seat is a bit low already.
0:20:20 > 0:20:23He's building a customised bike for Oscar
0:20:23 > 0:20:26and he needs precise measurements.
0:20:26 > 0:20:27Pedal fast.
0:20:29 > 0:20:30OK, steer left.
0:20:31 > 0:20:33And...brake now.
0:20:34 > 0:20:38- They're fine.- I think we've got the makings of a bike design.
0:20:40 > 0:20:42Once Yusuf has the measurements,
0:20:42 > 0:20:46he transfers them onto the rear of a tandem bike for Oscar to test.
0:20:48 > 0:20:49But there's a problem...
0:20:49 > 0:20:51I'm not going on this.
0:20:51 > 0:20:52No.
0:20:52 > 0:20:54Oscar's never been on a moving bicycle before.
0:20:54 > 0:20:55He's worried.
0:20:57 > 0:21:02- I'm worried.- Yeah.- I'm worried you're going to make me fall off...
0:21:02 > 0:21:05- Yeah.- ..and I don't really think I can ride a bike.
0:21:05 > 0:21:07I'm scared.
0:21:07 > 0:21:08They're my worries.
0:21:08 > 0:21:11I think it's natural to feel scared.
0:21:11 > 0:21:14- I'm not riding it. - It's a scary thing.
0:21:14 > 0:21:16- I will only do it...- Yeah.
0:21:16 > 0:21:21..if someone is holding the back of me.
0:21:21 > 0:21:23Because if I fall, I don't want to die.
0:21:23 > 0:21:26- You're not going to die. - It's only a bike.- Oh...!
0:21:26 > 0:21:28Go on, have a go.
0:21:31 > 0:21:33If I fall off, I'm suing!
0:21:33 > 0:21:35OK.
0:21:35 > 0:21:36No jokes.
0:21:36 > 0:21:40OK, so we're going to start slowly, I'm not going to pedal,
0:21:40 > 0:21:43we're just going to go forward, OK?
0:21:43 > 0:21:45So you pedal, you pedal.
0:21:45 > 0:21:46You pedal.
0:21:46 > 0:21:47Trust him.
0:21:51 > 0:21:53Please, help me.
0:21:53 > 0:21:58OK, now I think it would be worth giving a go without Mum.
0:21:58 > 0:22:00- No, that's not happening! - Go on, then.- Fine.
0:22:00 > 0:22:03I'll hold on if that's going to be a problem.
0:22:03 > 0:22:04- Go.- Here we go.
0:22:04 > 0:22:06Come on, then.
0:22:09 > 0:22:11Mum...!
0:22:11 > 0:22:12I'm here. I'm holding on.
0:22:12 > 0:22:14Holding the balance, yeah?
0:22:14 > 0:22:15Yeah.
0:22:19 > 0:22:21Think you can let go, Mum.
0:22:21 > 0:22:23I am letting go.
0:22:28 > 0:22:29Look up.
0:22:29 > 0:22:31Easy.
0:22:31 > 0:22:32Ready to stop?
0:22:32 > 0:22:34Again, again, again!
0:22:34 > 0:22:36Ready to go again?
0:22:36 > 0:22:38Mum, you've got to hold me!
0:22:38 > 0:22:39Ready?
0:22:43 > 0:22:45Easy. We've got this.
0:22:45 > 0:22:47Great work.
0:22:48 > 0:22:50Go all the way.
0:22:50 > 0:22:52Keep going! Keep going! Keep going to the end!
0:22:52 > 0:22:54Keep going to the end!
0:22:54 > 0:22:57Wonderful to see and he's absolutely thrilled about it
0:22:57 > 0:22:59because he wants to keep doing it and doing it and doing it.
0:22:59 > 0:23:01It's lovely.
0:23:03 > 0:23:06It's about him being the same.
0:23:06 > 0:23:09It's just kids their age, however thoughtful they are,
0:23:09 > 0:23:11at some point they're going to want to cycle away
0:23:11 > 0:23:14and then he's left standing there on his own.
0:23:14 > 0:23:15Keep going!
0:23:15 > 0:23:18And I didn't want him to have to go through that.
0:23:18 > 0:23:22If he's got a bike, he's able to be the same as everybody else.
0:23:25 > 0:23:27- Thank you, Yusuf.- Yeah, no problem.
0:23:27 > 0:23:30- Is my hair messed up? - No, it's perfect.
0:23:30 > 0:23:31It's good, yeah.
0:23:38 > 0:23:43Yusuf begins designing a bespoke BMX bike for Oscar.
0:23:44 > 0:23:47I'd like to move the seat slightly more forward
0:23:47 > 0:23:49and a little bit more upright.
0:23:49 > 0:23:51What this is going to do is allow Oscar
0:23:51 > 0:23:53to put most of his weight on his bum.
0:23:53 > 0:23:56Changing the angle of the seat post
0:23:56 > 0:23:59has a knock-on effect for every angle on the bike frame.
0:23:59 > 0:24:02I'm going to set this...
0:24:02 > 0:24:03to 260.
0:24:03 > 0:24:06Steel tubes are cut precisely to match Yusuf's drawings...
0:24:11 > 0:24:12..then TIG welded together to make the frame.
0:24:14 > 0:24:17It's a long process with some late nights for Yusuf.
0:24:21 > 0:24:24While Yusuf is building, Oscar's in training.
0:24:24 > 0:24:26Go, Oscar, pedal, pedal, pedal.
0:24:26 > 0:24:30He's learning from professional cycling coach Lisa Costa.
0:24:30 > 0:24:33I think what we'll do, you've got more length that way.
0:24:33 > 0:24:34So if we go down there...
0:24:34 > 0:24:37Oscar's made good progress on the mountain bike,
0:24:37 > 0:24:40but because he can't pull on the handlebars,
0:24:40 > 0:24:42starting and stopping is proving tricky.
0:24:42 > 0:24:43Pedal, pedal, pedal.
0:24:43 > 0:24:47Designing the fixes is a long, arduous process.
0:24:47 > 0:24:49Well done. Give me a high five.
0:24:49 > 0:24:50It's three months since the first prototype
0:24:50 > 0:24:55and only now has Yusuf been able to complete version two of the BMX.
0:24:55 > 0:24:56So...
0:24:58 > 0:25:00Wow! Look at that.
0:25:00 > 0:25:03This here is the prototype.
0:25:03 > 0:25:06A BMX-style frame, BMX wheels.
0:25:06 > 0:25:09- What do you think, Oscar? - Yeah, I like it.
0:25:09 > 0:25:11What about you, Lisa?
0:25:12 > 0:25:14Practical wise, I'm a little bit concerned.
0:25:16 > 0:25:20- Because there's no gearing. - Yep.- It's quite hilly round here.
0:25:20 > 0:25:22He'll find it difficult going up the hills with this.
0:25:22 > 0:25:26Lisa's also concerned about the BMX's dimensions.
0:25:26 > 0:25:28If you just want to get on the bike for us.
0:25:32 > 0:25:35His whole posture's... It's just too forward.
0:25:35 > 0:25:38- Yeah. And you see how high his knees are coming up?- Yeah.
0:25:40 > 0:25:42We need shorter cranks.
0:25:42 > 0:25:43Yeah, we do.
0:25:43 > 0:25:47But shortening cranks, the stems for the pedals,
0:25:47 > 0:25:49will make pedalling harder.
0:25:49 > 0:25:51I do really want a BMX.
0:25:51 > 0:25:54I am super keen that...
0:25:55 > 0:25:58..this BMX frame,
0:25:58 > 0:26:01we find a configuration that will work with him.
0:26:01 > 0:26:04If you don't succeed, try, try, try again.
0:26:06 > 0:26:09I always find, as a designer, you just get,
0:26:09 > 0:26:12people tell you it's completely wrong over and over again
0:26:12 > 0:26:13until it's right.
0:26:13 > 0:26:16So you have to kind of have a thick skin
0:26:16 > 0:26:20and you have to appreciate that, ultimately, in order for it to work,
0:26:20 > 0:26:23it's going to be wrong for a long...
0:26:23 > 0:26:25It's going to be wrong for a while, if that makes sense.
0:26:25 > 0:26:29So, yeah, we'll just have to roll with the punches
0:26:29 > 0:26:33and back to the drawing board and get him what he needs.
0:26:37 > 0:26:41The Fix Team are about to begin their third case,
0:26:41 > 0:26:44tackling one of the UK's biggest rural crimes -
0:26:44 > 0:26:46sheep rustling.
0:26:47 > 0:26:49I'm in Somerset to meet Mike,
0:26:49 > 0:26:52a farmer whose livelihood is being threatened
0:26:52 > 0:26:54by criminals stealing his sheep in the dead of night.
0:26:56 > 0:26:58What's happened when you've lost sheep before?
0:26:58 > 0:26:59Can you just describe it?
0:26:59 > 0:27:01They pinched them in two Transit vans.
0:27:01 > 0:27:03And one of the Transit vans broke down.
0:27:04 > 0:27:07And they left them in the back of the Transit van.
0:27:07 > 0:27:11Then, when we let them out, nine of them were dead, they got suffocated,
0:27:11 > 0:27:12or they were trampled to death.
0:27:12 > 0:27:14To me, that was awful.
0:27:14 > 0:27:18What sort of people would just leave sheep to die in them circumstances,
0:27:18 > 0:27:20or let anything die in them circumstances?
0:27:22 > 0:27:25Sheep rustling is one of the oldest crimes in Britain
0:27:25 > 0:27:27and it's an increasing problem.
0:27:27 > 0:27:31It's thought almost 100,000 sheep are stolen every year,
0:27:31 > 0:27:34costing farmers millions of pounds.
0:27:34 > 0:27:36How much of a problem is it around here?
0:27:36 > 0:27:38Last year was a real problem.
0:27:38 > 0:27:39The numbers are getting bigger.
0:27:39 > 0:27:42Whereas it used to be twos and threes and fours and fives,
0:27:42 > 0:27:45now it's trailer-loads, lorry-loads.
0:27:45 > 0:27:47- Entire flocks. - And there was one person up North
0:27:47 > 0:27:48who had 600 pinched one night.
0:27:48 > 0:27:50The police don't stand a chance.
0:27:50 > 0:27:51They've got to catch them red-handed.
0:27:54 > 0:27:57I fed back what I'd learnt to the team in London.
0:27:58 > 0:28:00Both sides of my family are farmers,
0:28:00 > 0:28:02so I'm kind of aware of actually what it's like
0:28:02 > 0:28:06to try and control a rural space.
0:28:06 > 0:28:07An enormous challenge, I imagine.
0:28:07 > 0:28:10It's not like bolting your front door, is it?
0:28:10 > 0:28:12The space is the problem.
0:28:12 > 0:28:14We need to do a kind of Crimewatch reconstruction.
0:28:14 > 0:28:16So we need to find out as much as possible
0:28:16 > 0:28:18about how the different crimes were committed,
0:28:18 > 0:28:19find out what was in common.
0:28:19 > 0:28:21Because that's the only way we're going to really understand
0:28:21 > 0:28:23where the points that we can intervene,
0:28:23 > 0:28:24in order to prevent it, are.
0:28:27 > 0:28:28All right?
0:28:28 > 0:28:31Dr Zoe Laughlin and Jude Pullen have come to the farm.
0:28:33 > 0:28:36Mike and his three sons have agreed to reconstruct the night
0:28:36 > 0:28:37their sheep were stolen.
0:28:39 > 0:28:42Come on, Floss, here! Fetch them on.
0:28:42 > 0:28:44Fetch them on.
0:28:44 > 0:28:46Zoe is co-founder and director
0:28:46 > 0:28:50of the Institute of Making at University College London.
0:28:50 > 0:28:54So when you're rustled, I mean, they do it pretty silently?
0:28:54 > 0:28:57Yeah, they know what they're doing.
0:28:57 > 0:28:59And sheep will handle a lot different in the dark.
0:28:59 > 0:29:00Will they be quieter or louder, the sheep?
0:29:00 > 0:29:02They'll be quieter,
0:29:02 > 0:29:04but they'll group together more and run a lot easier.
0:29:04 > 0:29:06So you have to be kind of a skilled shepherd to round up sheep?
0:29:06 > 0:29:08Oh, you've got to know what you're doing, yeah.
0:29:08 > 0:29:09It's not as simple as it looks.
0:29:09 > 0:29:11Come on, Fern, here!
0:29:11 > 0:29:13Here, Fern! Here, Floss!
0:29:13 > 0:29:16- So we're going to see how fast we can get them in.- Yeah.
0:29:16 > 0:29:19- Under a minute I reckon. - Under a minute?
0:29:20 > 0:29:23Jude is an award-winning design engineer.
0:29:23 > 0:29:25Like Zoe, he also grew up in the countryside.
0:29:25 > 0:29:27These ones need to get going.
0:29:27 > 0:29:28HE WHISTLES
0:29:28 > 0:29:30Get in.
0:29:30 > 0:29:32The rustle happens at an impressive pace.
0:29:32 > 0:29:35Within moments, the sheep are in the trailer.
0:29:41 > 0:29:42So, this is pretty impressive.
0:29:42 > 0:29:45You're getting this done in a relaxed way in about two minutes.
0:29:45 > 0:29:48- Yeah.- And you're saying, if you wanted to,
0:29:48 > 0:29:49if you were a serious criminal,
0:29:49 > 0:29:51you could get this done in half that time?
0:29:51 > 0:29:54Easy, yeah. If you were pushing, you could, easily.
0:29:55 > 0:29:58- It's that simple.- That's it.
0:29:58 > 0:30:00You can't lock this road, because it's public access.
0:30:00 > 0:30:02Yeah, this is public, so we can't lock this road.
0:30:02 > 0:30:04Yeah, it's all too easy.
0:30:06 > 0:30:08Sheep rustlers nearly always work at night.
0:30:09 > 0:30:10They cut out identifying ear tags
0:30:10 > 0:30:14and can take the sheep almost anywhere for slaughter or sale.
0:30:14 > 0:30:16In the last ten years,
0:30:16 > 0:30:18only a handful of rustlers have been prosecuted.
0:30:22 > 0:30:24After the reconstruction, we head to a pub
0:30:24 > 0:30:26to talk through the potential solutions with Mike
0:30:26 > 0:30:28and a group of other local farmers.
0:30:29 > 0:30:34Zoe and Jude have got some bits of tech and kit to show you
0:30:34 > 0:30:38which, hopefully, we are going to be able to look at and pick apart.
0:30:38 > 0:30:40First, Zoe tries an infrared beam...
0:30:40 > 0:30:43- When something crosses the beam... - BEEPING
0:30:43 > 0:30:44..they sound an alarm.
0:30:44 > 0:30:46You could easily imagine them between
0:30:46 > 0:30:49exit and entry points of fields and that kind of thing.
0:30:49 > 0:30:51The problem with that is, we live there,
0:30:51 > 0:30:53and that's there,
0:30:53 > 0:30:55which is probably about two and a half miles.
0:30:55 > 0:30:58By the time we've got dressed, got a vehicle, got a dog...
0:30:58 > 0:31:00Because you would never go anywhere without a dog, would you?
0:31:00 > 0:31:04..and got up there, they could be long gone.
0:31:05 > 0:31:06Then ultra-violet dye,
0:31:06 > 0:31:08which is invisible until a UV light is shone on it.
0:31:09 > 0:31:12It could be something that would be triggered to spray.
0:31:12 > 0:31:15Criminals, you'd spray their truck, you'd spray the sheep.
0:31:15 > 0:31:19- But then you've got to find who the criminal is to read the mark.- Yeah.
0:31:19 > 0:31:21Then Jude shows off a sound-activated alarm
0:31:21 > 0:31:25which he's hoping will detect when the sheep are distressed.
0:31:25 > 0:31:26Now...
0:31:26 > 0:31:28- on the tray... - What is this?
0:31:28 > 0:31:33This device is, when the sort of bleats are at a gentle level,
0:31:33 > 0:31:35it wouldn't really send much of a signal.
0:31:35 > 0:31:37But when it gets too loud,
0:31:37 > 0:31:40it would transmit through this little device via Wi-Fi.
0:31:40 > 0:31:42And as you can see, if I check my phone,
0:31:42 > 0:31:45- it's been alerting me that... - Sheep alert.- Sheep alert.
0:31:45 > 0:31:47What do you think, gentlemen?
0:31:47 > 0:31:49Is something like that viable? Could it work?
0:31:49 > 0:31:52I think ewes with lambs at foot will bleat when they are distressed.
0:31:52 > 0:31:53Yeah.
0:31:53 > 0:31:56But store lambs, or hogs as we call them at this time of year,
0:31:56 > 0:31:58very rarely do they bleat.
0:32:00 > 0:32:01The farmers aren't convinced.
0:32:01 > 0:32:04They reject all of Zoe and Jude's first ideas.
0:32:04 > 0:32:06It's going to be a lot harder than they thought
0:32:06 > 0:32:07to combat sheep rustling.
0:32:15 > 0:32:16Back on Graham's case,
0:32:16 > 0:32:19Ross and Ruby have been called to Peterborough.
0:32:22 > 0:32:25Zoe's made a discovery that could revolutionise her project
0:32:25 > 0:32:27to give Graham back his voice.
0:32:28 > 0:32:30Is that what I think it might be?
0:32:31 > 0:32:33- Are these tapes of Graham? - Yeah.
0:32:33 > 0:32:35Oh, my God...
0:32:36 > 0:32:39Builders were working in the attic and found an old box full of tapes.
0:32:48 > 0:32:53Hello. Here's me, Graham, sitting with my daughter Louisa.
0:32:54 > 0:32:58It's the first time Zoe's heard her husband's voice since his stroke.
0:32:58 > 0:33:01Well, seven moods, you know?
0:33:02 > 0:33:03Shouting at me!
0:33:03 > 0:33:05Shouting at Louisa.
0:33:05 > 0:33:07- ROSS:- Is this Graham talking? - Yeah.
0:33:07 > 0:33:09Did he just say tea-time?
0:33:10 > 0:33:12Would you like a bottle on it?
0:33:16 > 0:33:18THEY ALL LAUGH
0:33:24 > 0:33:25I love it!
0:33:25 > 0:33:28- GRAHAM:- Ah... Let's have a big "Ah!" for Louisa.
0:33:31 > 0:33:34You're not supposed to throw stones at the video camera.
0:33:34 > 0:33:36- Here.- Argh!
0:33:40 > 0:33:42- GRAHAM:- Whooh! Whooh!
0:33:44 > 0:33:47- ROSS:- That's going to be great for getting people's attention.
0:33:47 > 0:33:49No, that's Graham.
0:33:50 > 0:33:52That is a strong look.
0:33:52 > 0:33:53Dad, say something.
0:33:53 > 0:33:55I'm knackered.
0:33:55 > 0:33:57A quick flash!
0:33:59 > 0:34:01- I told you he was naughty. - We can't have that.
0:34:01 > 0:34:02He is so naughty!
0:34:03 > 0:34:05Yay...!
0:34:06 > 0:34:09- LOUISA:- And it's really nice looking at these lovebirds.
0:34:11 > 0:34:15It's just amazing to actually see what he's really like.
0:34:16 > 0:34:18- That's wicked. - OR what he used to be like.
0:34:18 > 0:34:20Yeah, but he's still... He is still there.
0:34:20 > 0:34:22- It's just he can't get it out. - Yeah.
0:34:24 > 0:34:25Hard.
0:34:25 > 0:34:28Now Ruby and Ross will take the tapes away
0:34:28 > 0:34:31to see if they can build Graham's own voice into their invention.
0:34:35 > 0:34:40Seeing him in those videos and seeing who he was...
0:34:41 > 0:34:46..and for him to have lost that, imagine if that happened to you.
0:34:46 > 0:34:49And imagine if you went from who he was
0:34:49 > 0:34:51to being in the position he's in now.
0:34:51 > 0:34:54The fact that you would have any positivity about anything after that
0:34:54 > 0:34:56is just amazing, absolutely amazing.
0:34:56 > 0:34:59Anyway, I thought I needed to say that while I was thinking about it.
0:35:01 > 0:35:05While Ross and Ruby start trawling through the tapes of Graham's voice,
0:35:05 > 0:35:08Yusuf is making progress with Oscar's bike.
0:35:09 > 0:35:12There's a lot more that we need to do on the handlebars
0:35:12 > 0:35:16to make him comfortable, to make him feel stable.
0:35:16 > 0:35:19Oscar can't grip the handlebars,
0:35:19 > 0:35:23so Yusuf designs and 3D prints various wrist attachments.
0:35:27 > 0:35:29But Oscar doesn't want obvious disability aids on his bike.
0:35:31 > 0:35:32Yusuf hits on a solution...
0:35:34 > 0:35:38If we were to use Velcro and create a...
0:35:39 > 0:35:41..almost like a wristband for him.
0:35:42 > 0:35:46What it would mean is that we could have a surface on the handlebars
0:35:46 > 0:35:50that he could...clip down into.
0:35:50 > 0:35:54The idea that he could kind of steer with it is one I'd like to explore.
0:35:57 > 0:36:00Yusuf is getting help a little closer to home
0:36:00 > 0:36:03from an expert he knows can manufacture a Velcro armband.
0:36:05 > 0:36:08My mum is helping out create the armbands.
0:36:10 > 0:36:14The Velcro pads seem to be fairly easy to...
0:36:14 > 0:36:16SEWING MACHINE JAMS
0:36:17 > 0:36:22What you get is a very strong grip being formed.
0:36:23 > 0:36:26So strong that I can hold the handlebar.
0:36:27 > 0:36:30But if Oscar is in danger, it easily rips off.
0:36:32 > 0:36:34And with a few final tweaks,
0:36:34 > 0:36:37it's time to put the months of work to the test.
0:36:37 > 0:36:39I feel very responsible.
0:36:39 > 0:36:42I don't want to put him in harm's way.
0:36:42 > 0:36:46Also, I don't want to disappoint him. He's put a lot of faith in me.
0:36:48 > 0:36:50- Good luck.- Thanks, man. Thanks.
0:36:51 > 0:36:52In a park near his home,
0:36:52 > 0:36:55Oscar and his friends and family are waiting
0:36:55 > 0:36:57to see if he can ride a bicycle.
0:36:59 > 0:37:03Over the last eight months, Yusuf has built not one but two bikes.
0:37:03 > 0:37:07A mountain bike for longer journeys and also Oscar's dream bike,
0:37:07 > 0:37:08an incredible BMX.
0:37:08 > 0:37:10That's fantastic.
0:37:11 > 0:37:17The smartest BMX that you will see in Sandwell and Dudley.
0:37:19 > 0:37:23Yusuf straps the Velcro band to one of Oscar's arms,
0:37:23 > 0:37:25the other arm is free to push the lever
0:37:25 > 0:37:27that operates the front and back brakes.
0:37:27 > 0:37:29It's the moment of truth...
0:37:31 > 0:37:33Bike trainer Lisa is there to keep an eye.
0:37:35 > 0:37:36He's off.
0:37:38 > 0:37:39Yes!
0:37:39 > 0:37:41- Yeah!- Yay!
0:37:47 > 0:37:49Again!
0:37:56 > 0:37:58This is really, really wonderful.
0:38:01 > 0:38:03Once he can do this,
0:38:03 > 0:38:06then hopefully he'll realise that he can do anything.
0:38:06 > 0:38:09This feels to me like Yusuf has...
0:38:09 > 0:38:10Cracked it.
0:38:10 > 0:38:11You said it.
0:38:11 > 0:38:14- Thank you.- No problem, mate. My pleasure, my pleasure.
0:38:14 > 0:38:16That's fine. That's fine.
0:38:16 > 0:38:19Thank you. You've changed his life, Yusuf. I really appreciate it.
0:38:23 > 0:38:25I'm really intrigued to see where he goes with it.
0:38:25 > 0:38:28Is he going to be a Paralympic cyclist?
0:38:28 > 0:38:33Is he going to be a BMX stunt rider doing tricks?
0:38:33 > 0:38:34Who knows?
0:38:34 > 0:38:37His journey cycling is just kind of beginning.
0:38:41 > 0:38:44Hi, Malcolm. This is Zoe ringing about the sheep-rustling project.
0:38:44 > 0:38:46Have you got ten minutes for me to ask you a few questions?
0:38:46 > 0:38:51Having initially failed to impress the farmers with their tech,
0:38:51 > 0:38:53the team start speaking to the police, to vets
0:38:53 > 0:38:56and leave no stone unturned.
0:38:59 > 0:39:01So I've come to a livestock market
0:39:01 > 0:39:06to watch a sheep auction and really see how sheep are bought and sold.
0:39:09 > 0:39:11Through you come.
0:39:13 > 0:39:17Every sheep has an ear tag with an electronic chip
0:39:17 > 0:39:20which identifies it and the farm it's from.
0:39:21 > 0:39:24They tell me you are ear tag man.
0:39:24 > 0:39:26Do you do chips that go anywhere else on the body or in the body?
0:39:26 > 0:39:29- No.- It's just ear tags? - It is just ear tags.
0:39:29 > 0:39:33But thieves can easily remove the tags and replace them with new tags
0:39:33 > 0:39:37showing a different owner, stopping people knowing they've been stolen.
0:39:37 > 0:39:39OK, come on, I wasn't wrong. £80.
0:39:41 > 0:39:43Zoe thinks she has a solution.
0:39:45 > 0:39:46Those tags are vulnerable.
0:39:46 > 0:39:48So I think this fix is about making something
0:39:48 > 0:39:50that's internal to the sheep.
0:39:50 > 0:39:52Something that the sheep ingests,
0:39:52 > 0:39:54can stay in there for the life of the sheep
0:39:54 > 0:39:56but can be read by these readers.
0:39:56 > 0:40:00So really the next step is about prototyping those
0:40:00 > 0:40:02and looking at the materials.
0:40:02 > 0:40:03There's a lot to do.
0:40:03 > 0:40:07Back in London, Zoe begins planning with Jude and Ross.
0:40:07 > 0:40:10If we can get somehow a tag inside the sheep,
0:40:10 > 0:40:11then it couldn't be removed.
0:40:11 > 0:40:13So sheep actually have something
0:40:13 > 0:40:16that they already ingest if they need mineral supplements
0:40:16 > 0:40:17and that's a bolus.
0:40:17 > 0:40:20So this is an example of a bolus.
0:40:20 > 0:40:21Sheep eat stones all the time
0:40:21 > 0:40:26and part of their stomach is designed to hold heavy objects.
0:40:26 > 0:40:28If we could somehow get a tag inside a bolus,
0:40:28 > 0:40:31then we're looking at essentially an internal tag
0:40:31 > 0:40:34which is much less easy to remove.
0:40:34 > 0:40:37The problem with the current electronic ear tag
0:40:37 > 0:40:42is it uses radio waves and needs a specialist scanner to read it.
0:40:43 > 0:40:45Jude has a more modern solution.
0:40:45 > 0:40:47You might want to consider one of these things,
0:40:47 > 0:40:49which is a Bluetooth transmitter.
0:40:49 > 0:40:51Also, a key benefit of that
0:40:51 > 0:40:53is that anyone can read it with their smartphone.
0:40:53 > 0:40:54We can give people an app
0:40:54 > 0:40:56and then anyone can look out for stolen sheep.
0:40:57 > 0:41:02So with the app on a smartphone and a Bluetooth bolus inside a sheep,
0:41:02 > 0:41:05anyone can become a stolen sheep detective.
0:41:05 > 0:41:10So can you get a Bluetooth chip into something this size
0:41:10 > 0:41:11or maybe, maximum, that size?
0:41:11 > 0:41:13- So that's about as big as it can get.- Yeah.
0:41:13 > 0:41:16A bolus can sit in a sheep's stomach for its whole life
0:41:16 > 0:41:18without causing any harm.
0:41:19 > 0:41:21It's a perfect place to hide a tracking device.
0:41:21 > 0:41:24So we need that inside that
0:41:24 > 0:41:26and a phone that can pick it up.
0:41:26 > 0:41:28Yeah!
0:41:31 > 0:41:32Jude gets straight to work.
0:41:32 > 0:41:35He miniaturises the components
0:41:35 > 0:41:39and uses his 3D printer to build a tiny case for the batteries.
0:41:40 > 0:41:43Doctor of material Zoe will make the housing for the electronics.
0:41:45 > 0:41:51Right, so, I'm going to attempt to make a ceramic case
0:41:51 > 0:41:54in which the electronic gubbins will live.
0:41:54 > 0:41:55So I've made some plaster blanks.
0:41:55 > 0:41:58I can then drill holes into them.
0:42:00 > 0:42:02So I'll just get a bit of slip in here.
0:42:03 > 0:42:05Pour it into the mould.
0:42:05 > 0:42:08Once it's been in the mould for a minute or so...
0:42:08 > 0:42:10skin starts to form
0:42:10 > 0:42:14and you can tip out the remaining liquid clay.
0:42:14 > 0:42:19What's left is a wall and a skin of more solid stuff.
0:42:19 > 0:42:23I'm going to put them in the oven just to slowly dry them.
0:42:24 > 0:42:26Ta-da!
0:42:26 > 0:42:29So that's a slip cast cylinder
0:42:29 > 0:42:33which then needs to be fired at 1,260 centigrade.
0:42:33 > 0:42:35And that will vitrify the material.
0:42:36 > 0:42:40Fingers crossed...nothing cracks or explodes.
0:42:41 > 0:42:45After 36 hours, Zoe's joined by Jude
0:42:45 > 0:42:47and then she lifts the lid on the kiln.
0:42:50 > 0:42:53Look at them, the little beauties.
0:42:53 > 0:42:54Oh, I'm pleased with that.
0:42:54 > 0:42:58And a battery-powered Bluetooth chip is ready to go.
0:42:59 > 0:43:01Can we see if your thing fits into my slot?
0:43:01 > 0:43:04- Boom, boom!- That's a good idea. - Just to kick us off.
0:43:06 > 0:43:07OK.
0:43:10 > 0:43:11Perfect.
0:43:12 > 0:43:15Finally, the team dip the boluses in non-toxic wax
0:43:15 > 0:43:17to make them easier to swallow,
0:43:17 > 0:43:20add the electronics and seal the lids.
0:43:23 > 0:43:26Past ten o'clock at night and I go a bit doolally.
0:43:26 > 0:43:29A visit to the shops has given Jude another idea...
0:43:29 > 0:43:33A way of making the existing ear tags tamper-proof.
0:43:34 > 0:43:39I have an ear tag and I have a tamper-evident tag,
0:43:39 > 0:43:41which you might have seen in clothing stores.
0:43:41 > 0:43:46These things spray ink all over your stolen shirt
0:43:46 > 0:43:47if you try and remove these.
0:43:49 > 0:43:50Whoo-hoo!
0:43:50 > 0:43:55I'm wondering whether that can actually be used to house the ink.
0:43:55 > 0:43:57Here goes.
0:43:59 > 0:44:01It's my replica sheep's ear.
0:44:01 > 0:44:04Let's see what happens when we cut through it.
0:44:06 > 0:44:09So, there. That's quite a good amount.
0:44:11 > 0:44:14So any rustler that cuts through Jude's ear tags
0:44:14 > 0:44:18will mark themselves and the sheep with indelible dye,
0:44:18 > 0:44:20making the sheep almost impossible to sell at auction.
0:44:20 > 0:44:23We've got the ink spike here
0:44:23 > 0:44:26and that's both blue for the visual
0:44:26 > 0:44:31but it also contains UV invisible dye, but is visible with this.
0:44:33 > 0:44:34After four months' work,
0:44:34 > 0:44:38the team have now come up with two new ideas to deter the criminals.
0:44:38 > 0:44:42A tamper-proof ear tag and a hidden tracking device.
0:44:42 > 0:44:46We appear to have got the prototyping done,
0:44:46 > 0:44:47so here it is...
0:44:49 > 0:44:51Now they need to put them to the test.
0:44:56 > 0:45:00In London, Ross is building a replacement for Graham's stylus.
0:45:00 > 0:45:02He's calling it the D-pad.
0:45:04 > 0:45:08Just a very quick, very small, very light little device
0:45:08 > 0:45:12for Graham to carry around or have with him
0:45:12 > 0:45:16and it's going to allow him to control the app using arrow keys.
0:45:17 > 0:45:21Ross enlists the help of his fiancee Isabel to build the D-pad.
0:45:22 > 0:45:24It's going to have a touch screen
0:45:24 > 0:45:26similar to the ones found on Smartphones.
0:45:26 > 0:45:29These work by sensing tiny electrical currents
0:45:29 > 0:45:31generated by contact with your fingers.
0:45:33 > 0:45:35With the lightest touch,
0:45:35 > 0:45:38Graham will be able to operate his tablet computer.
0:45:40 > 0:45:42They make the buttons
0:45:42 > 0:45:45by putting conductive paint on clear plastic vinyl.
0:45:50 > 0:45:52The electric buttons will then be mounted
0:45:52 > 0:45:55on incredibly light corrugated plastic,
0:45:55 > 0:45:57which Ross cuts with a laser cutter.
0:45:58 > 0:46:00Perfect.
0:46:02 > 0:46:05Meanwhile, Ruby is on a business trip in China.
0:46:05 > 0:46:08She's deciding the order of the statements,
0:46:08 > 0:46:11either in Graham's voice or using TV or film clips,
0:46:11 > 0:46:14using a computer programme called a wireframe.
0:46:15 > 0:46:16The point of wireframe
0:46:16 > 0:46:20is to communicate to the rest of your team how the app should work.
0:46:20 > 0:46:23It allows you to just work out what's on this screen,
0:46:23 > 0:46:26where does it go, what can it do?
0:46:28 > 0:46:30Both of them are now working through the night
0:46:30 > 0:46:33to get Graham's device ready as quickly as possible.
0:46:34 > 0:46:36It's quarter to one.
0:46:37 > 0:46:39The D-pad is wired up
0:46:39 > 0:46:42and I think I've written the code...
0:46:43 > 0:46:45..but I can't get it to upload to the board.
0:46:47 > 0:46:50And I think maybe it's to do with the way I've wired it up, but...
0:46:51 > 0:46:53..I'm not sure how to fix it.
0:46:59 > 0:47:02After months of work, we are back at Mike's farm
0:47:02 > 0:47:04getting ready to re-enact another sheep rustle.
0:47:05 > 0:47:07But this time the farm will be monitored
0:47:07 > 0:47:12by our team's specially-built sheep protection app - Herd It.
0:47:12 > 0:47:13Be scared.
0:47:13 > 0:47:16- Mike!- All right?
0:47:16 > 0:47:18- Hiya.- Good to see you.
0:47:18 > 0:47:19Oh... Nice pooey hands!
0:47:21 > 0:47:23- These guys have been working hard on your behalf.- Have they?
0:47:23 > 0:47:26- Does it work?- That's what were going to find out today.
0:47:26 > 0:47:31So what we've got is a combination of two things.
0:47:31 > 0:47:35A bunch of ear tags, which are going to have dye in them.
0:47:35 > 0:47:38The other side of it is you're familiar with boluses,
0:47:38 > 0:47:42which is what you'd use with your standard applicator,
0:47:42 > 0:47:44but we've basically put electronics in it
0:47:44 > 0:47:46that are going to transmit a signal like a beacon.
0:47:48 > 0:47:50First, Jude's ink ear tags
0:47:50 > 0:47:52are fitted in the existing holes in the sheep's ears.
0:47:54 > 0:47:57So there we go. You can see it just coming through here
0:47:57 > 0:48:00and there we go, clips in.
0:48:00 > 0:48:02- Very simple.- Bob's your teapot.
0:48:03 > 0:48:05- To take that ear tag out...- Yeah?
0:48:05 > 0:48:08Oh, I see, you'd have to cut it there.
0:48:08 > 0:48:11- You'd have to get a pair of scissors.- I'm learning, aren't I?!
0:48:11 > 0:48:12No, no, no, that's good.
0:48:12 > 0:48:14- If you cut there...- Yeah, yeah.
0:48:14 > 0:48:18I know. Yeah, no, no. I let you off there, that's pretty good.
0:48:19 > 0:48:22The bolus is swallowed painlessly by the sheep,
0:48:22 > 0:48:25with the welfare of the animal monitored by a local vet.
0:48:27 > 0:48:29She won't know anything about that.
0:48:29 > 0:48:32- It's something that you do all the time on the farm?- Yeah.
0:48:32 > 0:48:34It's time to put the tech to the test.
0:48:35 > 0:48:37Crack on with your rustle.
0:48:37 > 0:48:38Rustle!
0:48:38 > 0:48:40Fetch them on, dogs!
0:48:40 > 0:48:41Get in!
0:48:41 > 0:48:45We've got to imagine it's the middle of the night, pitch-black,
0:48:45 > 0:48:46but the rustlers are out.
0:48:46 > 0:48:48The lorry's off.
0:48:51 > 0:48:54In the back of the van the first layer of protection comes into play,
0:48:54 > 0:48:56the ink ear tags.
0:49:00 > 0:49:01Well, let's just imagine the scene.
0:49:01 > 0:49:05I'm, let's say, an inspector monitoring for rural crime.
0:49:05 > 0:49:10Can see some suspicious blue on the ear of the sheep here and this one.
0:49:10 > 0:49:12You're not going to miss that.
0:49:12 > 0:49:13But look at his hands.
0:49:13 > 0:49:15Proof that he's been up to no good.
0:49:15 > 0:49:16How long will it stay on?
0:49:16 > 0:49:20So this is developed, this dye, for banks, and so it's permanent.
0:49:20 > 0:49:23You're rufty-tufty sheep farmers. What do you think?
0:49:23 > 0:49:26Yeah, no, it's very good, very good, right.
0:49:26 > 0:49:30But I still say that there's nothing tying them back to the owner.
0:49:30 > 0:49:31Yeah.
0:49:37 > 0:49:39As soon as sheep are off-loaded at the market,
0:49:39 > 0:49:41it's time to see if the bolus actually works.
0:49:42 > 0:49:45- So the minute I opened my phone it was telling me...- Instantly!- Yeah.
0:49:45 > 0:49:47"Found sheep."
0:49:47 > 0:49:50- "36846 from flock number four." - Yep.
0:49:50 > 0:49:52This is Mike's phone, as it were,
0:49:52 > 0:49:57saying your sheep was last spotted at this location.
0:49:58 > 0:50:01You just click, it opens the map.
0:50:01 > 0:50:03So there you are, it's saying that's where we are.
0:50:03 > 0:50:06It shows, look, they're at the livestock auction.
0:50:06 > 0:50:08You could ring up...
0:50:08 > 0:50:10And tell Andrew that I've caught him.
0:50:10 > 0:50:14Yeah, you could say you've got my nicked sheep here.
0:50:15 > 0:50:18The test was a spectacular success.
0:50:18 > 0:50:21The team hope all farmers will use this technology,
0:50:21 > 0:50:24meaning all their mobile phones become sheep detectors.
0:50:25 > 0:50:28As soon as a stolen sheep turns up, phones will pick the signal.
0:50:28 > 0:50:32They'll be nowhere for a stolen sheep to hide.
0:50:32 > 0:50:34If the ownership of that sheep was brought into question,
0:50:34 > 0:50:39we could find the bolus to prove that it's not the vendor's sheep.
0:50:39 > 0:50:41We could then immediately not offer it for sale,
0:50:41 > 0:50:43contact Mike, if it was his sheep,
0:50:43 > 0:50:45contact the police and put it in their hands.
0:50:45 > 0:50:47It sounds like, from what you're saying,
0:50:47 > 0:50:49that this could really, really work.
0:50:49 > 0:50:51I think every possibility, yeah,
0:50:51 > 0:50:56that it could be one of the only ways of identifying rustled sheep.
0:50:56 > 0:50:58I think it's a brilliant achievement
0:50:58 > 0:51:00which has potential to be rolled out across the country
0:51:00 > 0:51:02and revolutionise traceability in sheep.
0:51:02 > 0:51:06Wonderful to hear. You've got the technology to this point.
0:51:06 > 0:51:11What do you need to happen next to make this viable for other farmers?
0:51:11 > 0:51:14We need to take this as evidence that the principle works
0:51:14 > 0:51:17and take it to the National Sheep Association.
0:51:17 > 0:51:19The Farmers' Union, government departments...
0:51:19 > 0:51:21We need to ring people!
0:51:23 > 0:51:25That's fantastic, really.
0:51:25 > 0:51:27I mean, God, you know...
0:51:27 > 0:51:28Yeah, well done.
0:51:31 > 0:51:34Very impressive, that's all I can say on the subject.
0:51:34 > 0:51:36I mean, you've shot me down.
0:51:36 > 0:51:39Got to learn to use a phone properly now!
0:51:47 > 0:51:49Back in London, the team are working flat out
0:51:49 > 0:51:51to finish Graham's reaction pad.
0:51:51 > 0:51:55Ruby's building four main pages into the app she's devised.
0:51:55 > 0:52:00Attention, quick statements, emotions and environment.
0:52:00 > 0:52:04They should allow Graham to take part in any conversation.
0:52:04 > 0:52:07It's something that will last a lifetime.
0:52:07 > 0:52:11For as long as he has something to say or something to react to,
0:52:11 > 0:52:13he'll be able to use this
0:52:13 > 0:52:16and that's what's really exciting because it's an evolving tool.
0:52:17 > 0:52:19Working late into the night and the early morning,
0:52:19 > 0:52:22Ross has managed to finish the control pad.
0:52:22 > 0:52:26And to give Graham another option, in case his hand gets tired,
0:52:26 > 0:52:27he's building him a joystick, too.
0:52:32 > 0:52:35- Are you nervous?- Very nervous about the hardware not working,
0:52:35 > 0:52:37seeing as I was finishing it on the train up here.
0:52:37 > 0:52:38He actually hasn't had any sleep.
0:52:38 > 0:52:41- At all?- No.
0:52:41 > 0:52:44Do you feel more affected by the emotionality of it
0:52:44 > 0:52:46than some of the other fixes?
0:52:46 > 0:52:49I definitely felt a very, very strong emotional connection
0:52:49 > 0:52:52to this story right from the second that I saw it.
0:52:52 > 0:52:54He could be like your dad or your brother or anyone.
0:52:56 > 0:52:58When you well up like that, Ruby,
0:52:58 > 0:53:04and I see Ross swaying slightly with the exhaustion of the situation,
0:53:04 > 0:53:06you've really tried and committed to this.
0:53:07 > 0:53:09After six months,
0:53:09 > 0:53:11they hope they've built something that will change Graham's life.
0:53:11 > 0:53:13Hi, how are you?
0:53:13 > 0:53:14We're excited!
0:53:14 > 0:53:16It's lovely to see you both.
0:53:17 > 0:53:19Are you OK with us gathering around?
0:53:23 > 0:53:26Are you feeling a little bit excited or apprehensive?
0:53:32 > 0:53:33"Not too bad."
0:53:35 > 0:53:38What we've made for you, Graham, is...
0:53:38 > 0:53:41this iPad has an app that's been made especially for you,
0:53:41 > 0:53:44designed entirely around your requirements.
0:53:44 > 0:53:47The D-pad with buttonhole mount.
0:53:47 > 0:53:50- Complete with logo. - Complete with logo.
0:53:50 > 0:53:52When you see...
0:53:53 > 0:53:54..the phrases in here,
0:53:54 > 0:53:57when they've got quotation marks,
0:53:57 > 0:54:00it means that we've used, in some cases,
0:54:00 > 0:54:03Zoe's voice or clips from TV and films.
0:54:03 > 0:54:08But every time you see just the phrase written as it is...
0:54:09 > 0:54:14..we've actually found clips of you and your own voice
0:54:14 > 0:54:18from the home videos that we've dug out the attic.
0:54:20 > 0:54:24So that...they're actually you.
0:54:26 > 0:54:29We went through about 50 hours of footage.
0:54:31 > 0:54:34So it was really nice for us, actually,
0:54:34 > 0:54:37to hear you speak and see you move and...
0:54:38 > 0:54:39That was really great.
0:54:41 > 0:54:42- OK.- You ready?
0:54:42 > 0:54:44Cool.
0:54:48 > 0:54:49OK.
0:54:50 > 0:54:53All right, Graham. Over to you, I guess.
0:54:55 > 0:54:57- GRAHAM'S VOICE:- Thank you, Zoe.
0:55:01 > 0:55:03Thank you, Zoe.
0:55:03 > 0:55:05That's a big smile, Graham.
0:55:06 > 0:55:08Shall we open the door, Graham?
0:55:09 > 0:55:10Yes.
0:55:14 > 0:55:16Graham, do you want to get up?
0:55:16 > 0:55:17No.
0:55:19 > 0:55:22- No, not at the moment. - He's otherwise occupied.
0:55:25 > 0:55:27Graham, does this feel good?
0:55:30 > 0:55:31Yes.
0:55:31 > 0:55:34That, just in and of itself, must be an enormous relief to you both.
0:55:35 > 0:55:37- Yeah.- More.
0:55:37 > 0:55:39More. I want you to keep pressing it.
0:55:39 > 0:55:42OK, I don't care what you say.
0:55:43 > 0:55:45Have a well-earned rest
0:55:45 > 0:55:47and a drink.
0:55:50 > 0:55:51Zoe...
0:55:53 > 0:55:55Thanks, guys.
0:55:59 > 0:56:01It was you speaking.
0:56:04 > 0:56:07The app has hundreds of clips of Graham's voice
0:56:07 > 0:56:08and quotes from film and TV.
0:56:08 > 0:56:10More can be added at any time.
0:56:13 > 0:56:15- Is this going to help you communicate?- Yes.
0:56:15 > 0:56:16Hey...
0:56:16 > 0:56:19You got that out before I could finish the sentence.
0:56:19 > 0:56:22And he's only going to get faster and faster.
0:56:23 > 0:56:25- SCOTTISH VOICE:- I'm busy, fuck off!
0:56:25 > 0:56:26LAUGHTER
0:56:26 > 0:56:28Yes!
0:56:29 > 0:56:32So great to hear your voice coming through again.
0:56:32 > 0:56:35I told you to fuck off twice and yet you're still here!
0:56:35 > 0:56:37LAUGHTER
0:56:37 > 0:56:39All right, we'll take the hint.
0:56:42 > 0:56:44Thank you.
0:56:46 > 0:56:48It was kind of just even more amazing than I thought.
0:56:48 > 0:56:50He got so quick at it so fast.
0:56:50 > 0:56:51It was just so good.
0:56:51 > 0:56:55Give him a week, think how fast he's going to be in a week, I can't wait.
0:56:55 > 0:56:57Go on, have a hug.
0:56:57 > 0:56:59The team have finished their work.
0:56:59 > 0:57:03We leave Zoe and Graham to chat for the first time
0:57:03 > 0:57:05since his life-changing stroke.
0:57:05 > 0:57:08- GRAHAM'S VOICE: - I've just had a wash.- You have.
0:57:08 > 0:57:10- Are you ready to go out? - Yes.
0:57:11 > 0:57:13Are you sorry for anything?
0:57:15 > 0:57:16No!
0:57:18 > 0:57:20So when I leave here tonight, you can say...
0:57:20 > 0:57:22- See you tomorrow.- Yeah.
0:57:24 > 0:57:25I love you, Zoe.
0:57:25 > 0:57:27See you tomorrow.
0:57:30 > 0:57:33Our team's inventions are already changing lives.
0:57:34 > 0:57:38Oscar is getting more confident on his bike every day.
0:57:38 > 0:57:41The Fix Team are meeting farmers' unions
0:57:41 > 0:57:44to drum up interest in their sheep protection system.
0:57:44 > 0:57:46Graham has left hospital and moved back home.
0:57:46 > 0:57:51Ross and Ruby have designed extra functions for his reaction pad app.
0:57:52 > 0:57:53- GRAHAM'S VOICE:- Meow!
0:58:01 > 0:58:02Next time...
0:58:02 > 0:58:05I just trip over a lot and I can't stop.
0:58:05 > 0:58:08Can the team design a medical helmet with style
0:58:08 > 0:58:10for a young David Bowie fan?
0:58:10 > 0:58:13HE SINGS
0:58:13 > 0:58:16..and build technology to give a partially-sighted mum
0:58:16 > 0:58:19the freedom to go outdoors?
0:58:19 > 0:58:20We're here!
0:58:20 > 0:58:23And help two brothers break the monotony of daily treatment?
0:58:23 > 0:58:26And every time you blow, the red car accelerates.
0:58:26 > 0:58:29I have never, ever seen this before.
