0:00:53 > 0:00:55# Oh, yeah! #

0:00:57 > 0:01:00Oh, hello there. I'm just doing a bit of vacuuming...

0:01:01 > 0:01:05..with a vacuum cleaner that does it all by itself!

0:01:05 > 0:01:07That's clever, isn't it?

0:01:08 > 0:01:10BEEP!

0:01:10 > 0:01:13I hear a beep, I see a flash, I wonder what they're going to ask.

0:01:19 > 0:01:21- Hi, Nina!- Hi, Nina!

0:01:21 > 0:01:22Hi!

0:01:22 > 0:01:24We've got a question for you.

0:01:24 > 0:01:27What amazing things would we have in the future?

0:01:27 > 0:01:29That's a great question.

0:01:29 > 0:01:32What amazing things will we have in the future?

0:01:32 > 0:01:35I know there are some very exciting things

0:01:35 > 0:01:38that some very clever people are working on right now.

0:01:38 > 0:01:42- Come to my lab and we'll investigate.- See you soon, Nina.

0:01:42 > 0:01:44- Bye!- Bye.

0:01:44 > 0:01:47I'm going to need some help to answer this one,

0:01:47 > 0:01:49and I know just who to ask.

0:01:49 > 0:01:51OK, Neurons, time to get to work.

0:02:07 > 0:02:10ALL: Neurons at the ready, Nina.

0:02:10 > 0:02:12OK. Today's question is...

0:02:12 > 0:02:15"What amazing things will we have in the future?"

0:02:15 > 0:02:19Which Neuron will be most useful in helping us find the answer?

0:02:19 > 0:02:21ALL: Me! Me! Me!

0:02:21 > 0:02:23Will it be fabulous Felix?

0:02:23 > 0:02:27I can help so very much if you need the sense of touch.

0:02:27 > 0:02:29Will it be beautiful Belle?

0:02:29 > 0:02:31I send messages to brain from ear.

0:02:31 > 0:02:34If there's a sound, I'll help you hear.

0:02:34 > 0:02:35Will it be lovely Luke?

0:02:35 > 0:02:38For looking and seeing, day or night,

0:02:38 > 0:02:40I'll help you with your sense of sight.

0:02:40 > 0:02:42Will it be awesome Ollie?

0:02:42 > 0:02:45If it's pongy or whiffy but you can't tell,

0:02:45 > 0:02:47my messages help your sense of smell.

0:02:47 > 0:02:49Or will it be baby Bud?

0:02:49 > 0:02:51Sour, salty, bitter or sweet,

0:02:51 > 0:02:54I'm your taste buddy whenever you eat!

0:02:57 > 0:03:00It's all the Neurons!

0:03:00 > 0:03:02ALL: Go, Neurons! Go, Neurons! Go, Neurons!

0:03:02 > 0:03:05ALL: Go, Neurons! Go, Neurons! Go, Neurons!

0:03:05 > 0:03:07ALL: Go, Neurons!

0:03:07 > 0:03:10ALL: All Neurons hip-hop-happy to help, Nina.

0:03:10 > 0:03:12Today's question is...

0:03:12 > 0:03:15"What amazing things will we have in the future?"

0:03:15 > 0:03:17We'll need help from all our Neurons today.

0:03:17 > 0:03:21I need to get the lab ready before the experimenters arrive.

0:03:22 > 0:03:25Leanna loves reading animal books.

0:03:25 > 0:03:27Selma likes gymnastics.

0:03:27 > 0:03:30There are new things since my mum was young.

0:03:30 > 0:03:33Making new things is fun.

0:03:33 > 0:03:34But they both want to know

0:03:34 > 0:03:37what amazing things we'll have in the future,

0:03:37 > 0:03:39so, today, for one day only,

0:03:39 > 0:03:42Leanna and Selma become the experimenters!

0:03:47 > 0:03:49- Hi, guys!- Hi, Nina.- Hi, Nina.

0:03:49 > 0:03:52Welcome to my lab and thanks for your great question -

0:03:52 > 0:03:55"what amazing things will we have in the future?"

0:03:55 > 0:03:58To find out, let's start by using our senses.

0:03:58 > 0:04:03ALL: Whoo-hoo! A senses experiment! We're ready, Nina!

0:04:03 > 0:04:05Technology is changing really fast

0:04:05 > 0:04:08and it's making our lives easier every day.

0:04:08 > 0:04:11But what will we have in the future?

0:04:11 > 0:04:15Well, I have a vacuum cleaner that drives itself.

0:04:15 > 0:04:18But how about a car that drives itself?

0:04:18 > 0:04:20Well, that's just silly!

0:04:20 > 0:04:23Cars can't drive themselves, Nina.

0:04:23 > 0:04:26Actually, Felix, people are working on them right now.

0:04:26 > 0:04:30But I think you guys need to find out more about driving cars

0:04:30 > 0:04:35by doing some driving yourselves, in these mini cars! Off you go!

0:04:39 > 0:04:42Ah, that's it. On you go, Leanna. Turn that wheel.

0:04:43 > 0:04:47Vroom-vroom! Good turn, experimenter! Ha-ha!

0:04:47 > 0:04:48Watch out for the desk!

0:04:48 > 0:04:50Ha-ha-ha!

0:04:50 > 0:04:52Oh, beautifully turned!

0:04:52 > 0:04:55That's it! Go for it!

0:04:56 > 0:04:58Great driving.

0:04:58 > 0:04:59Now when you were driving,

0:04:59 > 0:05:03you were doing lots of different things at once. So what were they?

0:05:03 > 0:05:05I turned the wheel and I looked around.

0:05:05 > 0:05:08- I pushed the pedals.- Yes.

0:05:08 > 0:05:09You had to turn the steering wheel

0:05:09 > 0:05:11and use your feet to move the pedals.

0:05:11 > 0:05:15And you had to look around, to make sure you didn't bump into anything.

0:05:15 > 0:05:18That's a lot of things to do at once.

0:05:18 > 0:05:20Driving is hard work, Nina.

0:05:20 > 0:05:21It can be, Felix.

0:05:21 > 0:05:25But what will cars be like in the future?

0:05:25 > 0:05:27Well, have a look at this.

0:05:27 > 0:05:30These cars can drive by themselves.

0:05:30 > 0:05:33The driver is still sitting behind the steering wheel

0:05:33 > 0:05:37but she can read a newspaper because the car's driving itself.

0:05:37 > 0:05:40How does a car drive itself, Nina?

0:05:40 > 0:05:43Well, the car is actually being driven by a computer.

0:05:43 > 0:05:45The computer controls what the car does.

0:05:45 > 0:05:48Some very clever people have thought about

0:05:48 > 0:05:50all the things you have to do to drive a car.

0:05:50 > 0:05:55And they've found a way to make a computer do the same things.

0:05:55 > 0:05:58I think we need to go on a bus ride to find out more.

0:06:03 > 0:06:06Hmm, where do you think we're going today?

0:06:06 > 0:06:08Nina said we were going on a bus ride.

0:06:08 > 0:06:12I hope it's a double-decker and we sit in the top!

0:06:12 > 0:06:15I do hope there's not a big queue at the bus stop.

0:06:15 > 0:06:17I don't think we're going to a bus stop, Neurons.

0:06:17 > 0:06:21OK, experimenters, so far we've found out that driving

0:06:21 > 0:06:24involves doing LOTS of different things at once

0:06:24 > 0:06:28and driverless cars are actually controlled by a computer.

0:06:28 > 0:06:33So I've brought you here to see this little bus to find out more!

0:06:33 > 0:06:36Now this shuttle bus takes people around this special place,

0:06:36 > 0:06:38where lots of scientists work.

0:06:38 > 0:06:40But can you see a driver?

0:06:40 > 0:06:41- BOTH:- No.

0:06:41 > 0:06:43No-one there, Nina.

0:06:43 > 0:06:47That's because this shuttle bus actually drives by itself.

0:06:47 > 0:06:48And as a special treat,

0:06:48 > 0:06:50I've arranged for US to have a ride on it.

0:06:50 > 0:06:52So, come on, let's hop on board!

0:06:55 > 0:06:56There you go.

0:06:58 > 0:07:01We need to tell the computer which journey we want to take.

0:07:01 > 0:07:03So can you press the button for me, Selma?

0:07:05 > 0:07:07OK, here we go!

0:07:11 > 0:07:12This is amazing!

0:07:12 > 0:07:15And VERY quiet!

0:07:15 > 0:07:17It's not like a normal bus or car.

0:07:17 > 0:07:20And I can't smell any whiffy engine fumes either.

0:07:20 > 0:07:24That's because this shuttle bus doesn't have the same type of engine

0:07:24 > 0:07:26that most buses and cars have.

0:07:26 > 0:07:27It doesn't use petrol.

0:07:27 > 0:07:32It uses electricity - we've a big battery to make it move.

0:07:35 > 0:07:39We've arrived safely! Well done, shuttle bus.

0:07:39 > 0:07:42Did the bus drive us anywhere, Nina?

0:07:42 > 0:07:44That's a good question.

0:07:44 > 0:07:47Well, the computer that controls the shuttle bus

0:07:47 > 0:07:49only knows how to drive along certain journeys.

0:07:49 > 0:07:52A person taught it those journeys

0:07:52 > 0:07:54so now it can follow them on its own.

0:07:54 > 0:07:57In the future, if the computers in cars and vehicles like this

0:07:57 > 0:07:59are given enough information,

0:07:59 > 0:08:02they could go absolutely ANYWHERE!

0:08:02 > 0:08:04So let's go back again.

0:08:13 > 0:08:16Oh, there's a parked car ahead.

0:08:16 > 0:08:20Mm, how will the shuttle bus spot the car?

0:08:20 > 0:08:22It can't see.

0:08:22 > 0:08:24Don't worry, Luke.

0:08:25 > 0:08:28Although the shuttle bus doesn't have eyes like we do,

0:08:28 > 0:08:30it still knows what's around it.

0:08:30 > 0:08:34When it senses something in front of it, that it could bump into,

0:08:34 > 0:08:38the computer in the shuttle bus makes the shuttle bus stop safely.

0:08:41 > 0:08:44And off we go!

0:08:49 > 0:08:51That was fun, wasn't it?

0:08:51 > 0:08:53- BOTH:- Yes!

0:08:53 > 0:08:55Now let me show you how this shuttle bus can see.

0:08:55 > 0:08:58So, as we found out earlier, when people drive,

0:08:58 > 0:09:01they need to use their eyes to see where they're going

0:09:01 > 0:09:03and to watch out for things they could bump into.

0:09:03 > 0:09:05But vehicles that can drive by themselves

0:09:05 > 0:09:07they don't have eyes like we do,

0:09:07 > 0:09:12instead they have special sensors like this

0:09:12 > 0:09:15that help them to see and work out where they are.

0:09:15 > 0:09:17How do the sensors work, Nina?

0:09:17 > 0:09:20Ooh, let's go back to the lab to find out.

0:09:22 > 0:09:25All cars that can drive themselves have special sensors,

0:09:25 > 0:09:27to sense what's around them.

0:09:27 > 0:09:30Let's do one final experiment to see how they work.

0:09:30 > 0:09:32The sensors on driverless cars

0:09:32 > 0:09:35send out a special kind of light which our eyes can't see.

0:09:35 > 0:09:38And when this light bumps into things -

0:09:38 > 0:09:40like the car that was in front of us earlier -

0:09:40 > 0:09:42something happens.

0:09:42 > 0:09:44So let's find out what.

0:09:44 > 0:09:46I just need to turn the lights down.

0:09:46 > 0:09:51I've got here a mirror and a torch.

0:09:53 > 0:09:55Now look.

0:09:55 > 0:09:57What's happened to the light?

0:09:57 > 0:09:59It bounced off the mirror, Nina.

0:09:59 > 0:10:03That's right. And the special light from the sensors on driverless cars

0:10:03 > 0:10:06bounces off things too -

0:10:06 > 0:10:10like other cars, people, buildings - in fact, everything.

0:10:12 > 0:10:15And the light bounces back to the sensor.

0:10:15 > 0:10:19If something is close to the sensor, it bounces back quite quickly.

0:10:19 > 0:10:21But if it's further way, it takes a bit longer.

0:10:21 > 0:10:25And that's how the car measures how far away things are.

0:10:25 > 0:10:28Let's do another experiment.

0:10:28 > 0:10:31We're going to pretend that this ball

0:10:31 > 0:10:34is the special light sent out by the sensors.

0:10:34 > 0:10:37I want you guys to roll the special light down the road

0:10:37 > 0:10:40and we'll see how long it takes to bounce back.

0:10:40 > 0:10:43OK, Selma, why don't you go first, my dear?

0:10:43 > 0:10:45And watching...

0:10:46 > 0:10:48All the way back! All the way back!

0:10:48 > 0:10:51Brilliant! The special light bounced back.

0:10:51 > 0:10:55- But it wasn't very quick, was it? - No, Nina.- No.

0:10:55 > 0:10:56OK, let's try it again.

0:10:56 > 0:11:00This time we'll see what happens if we put something in its way.

0:11:06 > 0:11:07So what happened?

0:11:07 > 0:11:09It bounced back quicker.

0:11:09 > 0:11:12Yes, the light didn't have as far to go

0:11:12 > 0:11:16before it bounced off the obstacle. So it bounced back much quicker.

0:11:16 > 0:11:19And this is just like the shuttle bus earlier.

0:11:19 > 0:11:21When something was in its path,

0:11:21 > 0:11:23the light bounced back to the sensor quicker

0:11:23 > 0:11:27so it knew something was in its way and the shuttle bus stopped.

0:11:27 > 0:11:29Some cars that are already on our roads

0:11:29 > 0:11:32use sensors to spot when something's too close to them,

0:11:32 > 0:11:36and they either stop or beep to warn the driver.

0:11:36 > 0:11:39Well, that could stop a lot of accidents, Nina.

0:11:39 > 0:11:40It could, Felix.

0:11:40 > 0:11:42In fact, cars that drive themselves

0:11:42 > 0:11:45could make driving much safer in the future.

0:11:45 > 0:11:50# Nina And The Neurons! #

0:11:50 > 0:11:51So your question was,

0:11:51 > 0:11:54"what amazing things will we have in the future?"

0:11:54 > 0:11:55And I think we've answered it.

0:11:55 > 0:11:58- FELIX:- We discovered that clever people

0:11:58 > 0:12:01are making cars that can drive themselves.

0:12:01 > 0:12:03The cars are controlled by a computer

0:12:03 > 0:12:07that can do the different things that people do when they drive.

0:12:07 > 0:12:09BELLE: The computer in the shuttle bus

0:12:09 > 0:12:13could only drive along certain journeys it had memorised.

0:12:13 > 0:12:16- LUKE:- The computer senses where the vehicle is going

0:12:16 > 0:12:21by using sensors that bounce special light off things around it

0:12:21 > 0:12:23to measure how far away things are.

0:12:23 > 0:12:26- BUD:- If something is blocking the road ahead,

0:12:26 > 0:12:32the computer will sense it and stop the wheels really quickly!

0:12:32 > 0:12:34I hope that's answered your question.

0:12:34 > 0:12:37- BOTH:- Thanks, Nina. Bye.

0:12:37 > 0:12:39You're welcome. Bye.

0:12:40 > 0:12:44If you want to know more about the science that's all around us, go to

0:12:44 > 0:12:46the Nina section on the CBeebies website.

0:12:46 > 0:12:47Have fun.
