:00:00. > :00:00.That is it for me. More on the website.
:00:00. > :00:16.This week, hitting the Hay to talk space and robots. Going underground
:00:17. > :00:22.to solve a mystery. And taking a walk in the park with a very special
:00:23. > :00:44.guest. What is that one to? -- what does that one to?
:00:45. > :00:56.A glorious weekend in it for Wales. This is he on Wye, known as the town
:00:57. > :01:00.of books. This is where authors, thinkers and even royals, to embrace
:01:01. > :01:06.their love of reading and discuss some of the biggest news of the day
:01:07. > :01:09.-- Hay-on-Wye. And once every year it becomes the centre of the
:01:10. > :01:14.literary world is the location of the Hay Festival. Of course it is
:01:15. > :01:18.also just a nice place to sit and read. The Hay Festival has been
:01:19. > :01:22.described as the literary Glastonbury. Literally. But it turns
:01:23. > :01:26.out you don't have to have a book out to be asked to talking. Case in
:01:27. > :01:31.point, in about ten minutes, we are on. To paraphrase the acting God
:01:32. > :01:40.that is Kevin Costner, if you build it, they will come. We did, and they
:01:41. > :01:44.did. Filling up the BBC tent as we brought Click life to an audience
:01:45. > :01:48.who were no Way bribe to be there that early on a Saturday morning. We
:01:49. > :01:53.brought the geek with talk of their hunt 60 degrees vision. If you try
:01:54. > :01:58.this, it looks as if you are sitting on my lap. We amazed signs with Dr
:01:59. > :02:08.Emily Grossman with 360 degrees sound. Wow! OK. Are you OK? Do you
:02:09. > :02:13.want to come out? I'm loving it. And we gave a sneak peek of our upcoming
:02:14. > :02:17.adventure in China. And it all ended with a musical climax where we play
:02:18. > :02:26.big tent. You heard me, we played the tent live. But we weren't the
:02:27. > :02:29.only geeks at Hay, some use the opportunity to meet and chat with
:02:30. > :02:36.some of the biggest names in science and Tech. First, virgin Galactic.
:02:37. > :02:40.Almost 18 months ago, the quest to build the world's first commercial
:02:41. > :02:46.space line suffered a major setback after a tragic accident. Can we deal
:02:47. > :02:53.with the crash first? Do we know why it happened? We know exactly what
:02:54. > :02:58.happened. After the accident in October 2014, a foreign
:02:59. > :03:03.investigation was undertaken by the NTSB, the US accident investigation
:03:04. > :03:08.board. They established over a period of six or seven months
:03:09. > :03:14.exactly what happened to cause the breakup of the spaceship. Having
:03:15. > :03:17.understood the causes of that accident, we have completed the
:03:18. > :03:21.build of a second spaceship. That was rolled out a few weeks ago in
:03:22. > :03:25.the desert. We are completing ground tests of that vehicle will be back
:03:26. > :03:29.into the test flight programme in a few weeks. When the original project
:03:30. > :03:33.was announced, the indication was you would be up and running within a
:03:34. > :03:40.short time. It has now taken a lot longer. What will be problems? What
:03:41. > :03:49.have you mind? We have learned that space is hard. And especially if you
:03:50. > :03:55.are building a vehicle when needs -- which needs to fly thousands of
:03:56. > :03:59.times with paying passengers who expect a high level of safety. None
:04:00. > :04:03.of that comes as a surprise to me. I would have thought that would be on
:04:04. > :04:09.the table from the beginning. We knew it was hard, but we put out --
:04:10. > :04:13.looked at what was potentially possible, and then you understand
:04:14. > :04:16.the true complexities and making sure you are not just delivering an
:04:17. > :04:20.extraordinary experience, but an extraordinarily safe experience. It
:04:21. > :04:26.is time-consuming. Are you aiming only at passengers? It seems to me
:04:27. > :04:29.if you were carrying freight to the International Space Station, it
:04:30. > :04:34.would make more money. Is that where you are going with this? Our focus
:04:35. > :04:41.to date has largely been on getting people into space. But we also
:04:42. > :04:45.recognise there is a huge demand right now for wanting small
:04:46. > :04:49.satellites into space. So satellites are getting smaller, smarter,
:04:50. > :04:53.cheaper and lighter. There is desire for the data they can generate up
:04:54. > :04:58.there. But the cost and availability of launch is as bad as it has been.
:04:59. > :05:02.It is one of these unusual industries which has proven itself
:05:03. > :05:05.to be incredibly important, but the technology used to get the payload
:05:06. > :05:08.up there has not changed dramatically in the last
:05:09. > :05:12.half-century. The other interesting thing is what we may be able to
:05:13. > :05:16.develop using this experience we gained from this first stage is to
:05:17. > :05:22.think about how we transport people on earth. It would be great to get
:05:23. > :05:27.from here to Australia in a couple of hours, which is possible going
:05:28. > :05:32.via space. And I think there could be big environmental benefits as
:05:33. > :05:35.well. We are very focused on getting this first step right, but we also
:05:36. > :05:47.spend a little time thinking what might come next. Nuclear explosions
:05:48. > :05:53.are caused by weapons such as age bonds or atom bombs. -- H bonds. The
:05:54. > :05:58.heat and blast is so severe it can kill. Welcome to the end of the
:05:59. > :06:04.world. This is the bunker, a new live action point and click video
:06:05. > :06:12.game set inside a nuclear shelter after a devastating atomic attack.
:06:13. > :06:16.The player adopts the role of John, born in the shelter on the date the
:06:17. > :06:20.bombs fell. 30 years later, he is the bunker's only surviving
:06:21. > :06:25.inhabitants. You can protect yourself and your family. And later
:06:26. > :06:30.on, we will show you what steps to take. Of course, there is more to it
:06:31. > :06:35.than just eating out an existence in a fallout shot. That would be boring
:06:36. > :06:40.as a game. -- eating. This unassuming cottage is the entrance
:06:41. > :06:51.to a real British bunker, and is the location for the game. What comes
:06:52. > :07:01.first? The story that you wanted to tell, or the game that you wanted to
:07:02. > :07:05.make? It really came from a sort of nugget of an idea which is a
:07:06. > :07:09.character alone in a very unusual space. And we wanted to create
:07:10. > :07:17.something really original around that. Facilities like this one,
:07:18. > :07:24.which protect from nuclear attack, are dotted all over the UK. This
:07:25. > :07:34.particular bunker was vacated by the Ministry of Defence in the early
:07:35. > :07:41.1990s. The bunker is a character. The fact that when we came here and
:07:42. > :07:46.everything was left, it was as if the government said it will probably
:07:47. > :07:51.not happen now, so we will just go. And leaving all of the evidence here
:07:52. > :07:56.and leaving all of these computers, systems and stationery, left every
:07:57. > :08:00.single bit and thought what can we include and use? Wanted to do right
:08:01. > :08:07.by the bunker. We almost wanted to tell its story. The game's visuals
:08:08. > :08:11.are filmed live action rather than computer-generated graphics. This
:08:12. > :08:21.means dozens of different options for how an event can be played have
:08:22. > :08:27.been filmed. Why go live action instead of just having some motion
:08:28. > :08:33.caption or Rudy monitors. Honestly, I don't know how to do that. I know
:08:34. > :08:40.how to film. -- 3-D monitors. In also want from our first object, The
:08:41. > :08:43.Hunting, which was is on the survival thriller, running around
:08:44. > :08:48.the woods. We thought we were onto something. Because it is live
:08:49. > :08:51.action, you can't physically control the main character with the
:08:52. > :08:57.joystick. It is an actor in the room. You are telling him where to
:08:58. > :09:05.go. You have to limit those things. John is played by Adam Brown, who
:09:06. > :09:09.appeared in The Hobbit trilogy. I kept asking where are we in the
:09:10. > :09:15.story, but it always changes for the game play. They could take me on a
:09:16. > :09:19.certain path, and another gamer would take me on a different path,
:09:20. > :09:26.and those stories, piecing it altogether. Sometimes I just went, I
:09:27. > :09:34.am just going with it. I trust the gamer to put me on the right path. I
:09:35. > :09:39.want this door sealed immediately! If he had gotten out of that door,
:09:40. > :09:43.we would be dead. While the action in a biker has been filmed
:09:44. > :09:46.underground, routeing the game together is taking place above
:09:47. > :09:51.ground at this studio in Wales -- bunker. The team have tools to
:09:52. > :09:56.bridge the divide between video footage and video game. So we use a
:09:57. > :10:00.visual scripting tool which allows people like me who don't know how to
:10:01. > :10:04.code are able to set up something like this, and then the code can
:10:05. > :10:09.manage that and make sure we stay within the guidelines of making a
:10:10. > :10:13.game. We start at the desk where you have the three options of picking up
:10:14. > :10:18.the wooden figure, having a look at the back of the computer screen, or
:10:19. > :10:23.checking the desk. Then two of those things are simple. You can go to a
:10:24. > :10:27.weird video, and the further you go down to the desk, it becomes more
:10:28. > :10:32.concentrated. You can go back to a previous loop and so forth and so
:10:33. > :10:38.forth. As I'm here already, it would be rude not to give an early build
:10:39. > :10:40.the game a go. They have taken some interesting decisions with the
:10:41. > :10:45.storytelling. We are drawn into the world through John's routine. You
:10:46. > :10:49.have to repeat things over and over again. It helps to correct this
:10:50. > :10:52.atmosphere which is very lonely and a bit oppressive. I'm immediately
:10:53. > :10:57.hit with a mystery. What has happened to the rest of the
:10:58. > :11:03.survivors? So far the inexperience is an intriguing mix of movie and
:11:04. > :11:06.mystery game. -- the experience. We will find out how these elements
:11:07. > :11:13.come together when the Finnish game arrives later this year. -- finished
:11:14. > :11:17.game. Welcome to the week in Tech. Twitter's live streaming video
:11:18. > :11:23.service announced plans to get users to police offensive comments.
:11:24. > :11:27.Comments flagged as inappropriate by one person will be sent to Iran Jury
:11:28. > :11:31.of other viewers who can confirm whether the post a problem or not --

:11:37. > :11:42.would you pay for a supposedly high-end mobile phone that Tom Hardy
:11:43. > :11:47.sort of approves of? For a smidgen over ?11,000, it could be yours. We
:11:48. > :11:52.caught up with Tom Hardy, the official ambassador, at its launch
:11:53. > :11:55.event this week. Can I ask a couple of questions about your own mobile
:11:56. > :12:00.phone usage? But was Tom Hardy, the official ambassador. What news
:12:01. > :12:07.round-up would be complete without a small number of robot stories. This
:12:08. > :12:15.robot now has eight 360 degrees camera on top. And a tech company
:12:16. > :12:18.would like you to meet this robot, which is designed to provide

:12:28. > :12:30.can change its voice. If you are still unimpressed by virtual
:12:31. > :12:36.reality, perhaps this will convince you. This meant said he wanted great
:12:37. > :12:41.the West game ever, and he may have succeeded. Much bit simulator places
:12:42. > :12:47.you in a righty of unrealistic environments and forces you to fend
:12:48. > :12:52.off wadis who direct and contort toward you.
:12:53. > :12:58.The thing I love most about coming back to the countryside is that all
:12:59. > :13:02.of the Londoners on the Click team get frayed by all of this ring
:13:03. > :13:07.staff. And that weird smelling air -- green stuff. The thing they worry
:13:08. > :13:14.about most is they can't get enable signal. Not much anyway. -- a mobile
:13:15. > :13:18.signal. A good quality data signal is still considered a bit of a
:13:19. > :13:21.luxury here. But we have been meeting the Indian developers who
:13:22. > :13:34.have a few data tricks up their sleeve. There is a choice selection.
:13:35. > :13:38.Don't get me wrong, I love Indian food, that these days, you can get
:13:39. > :13:42.food from all over the world. Online as well Indians are tucking into a
:13:43. > :13:48.feast taking to smart phones and guzzling data, using social media,
:13:49. > :13:51.movie downloads and great music. It would be wonderful if the networks
:13:52. > :14:02.were up to the job. But they are not. I think it is bad. Coverage
:14:03. > :14:07.usually goes down because a lot of people are trying to use the same
:14:08. > :14:12.network. Designing apps for creaking connections is becoming an Indian
:14:13. > :14:18.speciality. This man is a popular music streaming app, checking to
:14:19. > :14:26.make sure it makes it to the toughest network neighbourhoods.
:14:27. > :14:32.Usually it is about getting the right amount of buffering for the
:14:33. > :14:37.right time. To avoid buffer breaks, it gives itself a head start,
:14:38. > :14:43.fetching data from upcoming songs so the flow of data is an interrupted.
:14:44. > :14:51.When there is a squeeze on, it does away with surplus graphics. That
:14:52. > :14:56.data is a problem. Make them lean, and apps run on overloaded networks
:14:57. > :15:01.and budget devices. Many here get online with smart phones that are as
:15:02. > :15:07.cheap as chips. Well, in this case, noodles. These low-end devices are
:15:08. > :15:11.short on memory and can only host so many apps. It means there is a
:15:12. > :15:20.battle royal over at screen real estate. A number of online retailers
:15:21. > :15:27.have taken a kind of low carb approach, putting data on a diet
:15:28. > :15:32.with so-called light apps. We have a system where we optimise the
:15:33. > :15:37.experience, so this speed is 85% faster in a slow connection. You
:15:38. > :15:41.will probably see a bit of degradation in the images, for
:15:42. > :15:47.instance, because they are smaller size, but there is really no change
:15:48. > :15:52.in the overall experience. The experience is almost double the
:15:53. > :16:00.speed. India is a vast country that is short on cell towers. Much of the
:16:01. > :16:05.radio connection used by mobile connections is blocked for military
:16:06. > :16:10.use. Designers try to get more from less data, redesigning codex, for
:16:11. > :16:15.example. This output streams real-time video at a bit rate close
:16:16. > :16:36.to streamed audio. The internet's reach is spreading
:16:37. > :16:42.and stretching, linking many more of us to other people and things.
:16:43. > :16:54.India's fast and slim approach might just be what we need to avoid
:16:55. > :16:59.network overload. Back at the A festival, another
:17:00. > :17:02.fascinating talk on the this time from a reporter says. In his
:17:03. > :17:07.research he asks the question, why do robots with all that processing
:17:08. > :17:12.power and sensors, still find it so difficult to use legs? Especially
:17:13. > :17:18.when the animal world finds them the most natural way of getting about.
:17:19. > :17:24.We are trying to learn how we make motion in an efficient way. We can
:17:25. > :17:27.walk for hours and hours without any problems, but if you want to make
:17:28. > :17:32.robots walk in a similar way they can only walk for 20 or 30 minutes
:17:33. > :17:36.and they run out of battery. He argues that even the robots we have
:17:37. > :17:41.seen that can walk well are thinking about it too hard. Instead, we
:17:42. > :17:45.should build bodies that are naturally balanced, that stay
:17:46. > :17:51.upright, and that move without any processing power. The amazing,
:17:52. > :17:56.jawdropping moment from your presentation was the bit about the
:17:57. > :18:02.fish. Can you explain for our audience the bit about the fish? So,
:18:03. > :18:11.this is an experiment done by researchers in the US, who made a
:18:12. > :18:20.fish dead from a brain perspective, so they Iniesta -- anaesthetised it.
:18:21. > :18:25.If you put the fish on the table, it is just dead. As soon as he put it
:18:26. > :18:31.in a water flow it starts swimming. The reason is that to swim, the fish
:18:32. > :18:38.doesn't really need brain and muscle activities. All it needs is a
:18:39. > :18:41.well-designed body in the right environment, and it reacts to the
:18:42. > :18:45.right stimulus from the physical environment. How hard is it to make
:18:46. > :18:53.a body that walks by itself? You showed a video of a body that walks
:18:54. > :18:56.by itself. How hard is that? You have to think about many different
:18:57. > :19:03.things. You have to think about the weight of the body, the weight
:19:04. > :19:09.distribution, the friction, dumping, also the shape of the foot is very
:19:10. > :19:13.important. Mechanically it is challenging to design, but once you
:19:14. > :19:19.decided it works. Can handle the real world best certainly do look
:19:20. > :19:22.weirdly organic. The trick, of course, is achieving in the lab what
:19:23. > :19:31.Mother Nature has spent millions of years perfecting.
:19:32. > :19:36.We are not the only ones working incredibly hard on this week's
:19:37. > :19:43.programme. Lara has been out and about in the park playing with some
:19:44. > :19:48.animals. This week I am testing some gadgets
:19:49. > :19:52.that need a little bit of help from man's best friend. I have been
:19:53. > :19:57.asking around the BBC for any suggestions and it seems that
:19:58. > :20:12.someone is making me here at midday. Wow! It is the dog from C BBC! Wow,
:20:13. > :20:22.it is Lara Lewington from BBC Click. Here I am making my rake out
:20:23. > :20:26.presenting debut on grown-up telly! Normally, it is us humans forget the
:20:27. > :20:30.great gadgets to play with. This week, I have something for you guys,
:20:31. > :20:36.so I wondered if you might be able to help me. There is even something
:20:37. > :20:46.to keep dogs fit and healthy. Will it involve running about? Yes, and
:20:47. > :20:52.you love that, don't you? Not me. I only do showbiz stuff. It is here my
:20:53. > :20:59.contract, I like sitting down. With it a go find a real dog. Can you
:21:00. > :21:02.make yourself useful? Item number one, the pit pat. This is like one
:21:03. > :21:09.of those human fitness track of things but it is for dogs. It clips
:21:10. > :21:16.tidily on the collar. It looks a bit chunky to me. It is available for
:21:17. > :21:19.iOS, Android and Windows phone. You set it up in pretty much the same
:21:20. > :21:24.way you do any activity tracker, only you need to input the breed of
:21:25. > :21:28.dog, as well as weight, age and gender. It should be able to tell
:21:29. > :21:37.you how much activity the dog needs to be getting and you can start
:21:38. > :21:40.tracking what it is actually doing. You can see how much activity the
:21:41. > :21:43.dog has been getting throughout the day, and if you want to look at what
:21:44. > :21:47.has been happening over the week, here is the full data, and you can
:21:48. > :21:56.tap on any day to get a bit more information. 210 minutes of activity
:21:57. > :22:09.on Sunday, that was a busy day! Item number two, a GPS tracker that
:22:10. > :22:13.dogs. Truffle! Truffle! Oh well. This has live GPS tracking, and it
:22:14. > :22:16.can tell you what your dog has been up to over the past 24 rows in case
:22:17. > :22:20.you don't already know, and it has a safe zone function. Can set up an
:22:21. > :22:23.area you are happy for the dog to be in and if adventures outside of that
:22:24. > :22:30.you will get an alert on your smartphone. This is an app that uses
:22:31. > :22:34.artificial intelligence to identify what breed of dog it is looking at.
:22:35. > :22:37.It can give you a percentage like us to familiar breed and can tell the
:22:38. > :22:45.difference between a real dog and an inanimate object, like a cat! I need
:22:46. > :22:49.a picture, that is perfect! It was spot on the Truffle, and some other
:22:50. > :22:56.dogs are tested it on. But it wasn't so lucky when it came to Lucky's
:22:57. > :22:59.mixed breed. And just to add a totally pointless but compelling
:23:00. > :23:03.extra, or you can photograph friends and family to see which dogged a
:23:04. > :23:12.most resemble. Although it did seem to think that he was real. This is
:23:13. > :23:16.quirky combination of snack feeder and Paul Thrower. It can entertain
:23:17. > :23:23.your pet when you can't and you can select the quantity of food you
:23:24. > :23:26.wanted to provide. It can be used in doors or outdoors, and after firing
:23:27. > :23:32.at Bulls for the dog to fetch, it will water them with snacks for
:23:33. > :23:35.returning them. Admittedly, it takes a bit of practice, but once they
:23:36. > :23:51.have got the knack it is a great way to wear them out. Isn't that right?
