:00:27. > :00:31.A glorious weekend in beautiful Wales.
:00:32. > :00:35.This is Hay-on-Wye, known as the town of books.
:00:36. > :00:38.This is where authors, thinkers and even royals come
:00:39. > :00:41.to embrace their love of reading and discuss some
:00:42. > :00:48.And once every year, it becomes the centre of the literary world as
:00:49. > :00:56.Of course it is also just a nice place to sit and read.
:00:57. > :00:59.The Hay Festival has been described as the literary Glastonbury -
:01:00. > :01:03.But it turns out you don't have to have
:01:04. > :01:08.Case in point, in about ten minutes, we're on.
:01:09. > :01:12.To paraphrase the acting God that is Kevin Costner, if you build it,
:01:13. > :01:22.Filling up the BBC tent as we brought Click live to an audience
:01:23. > :01:24.who were in no way bribed to be there that
:01:25. > :01:30.We brought the geek with talk of 360 vision.
:01:31. > :01:33.The weird thing about this, if you ever try this, it looks as
:01:34. > :01:39.We amazed science wiz Dr Emily Grossman with 360 sound.
:01:40. > :01:52.And we gave a sneak peek of our upcoming adventure in China.
:01:53. > :01:57.And it all ended with a musical climax where we played the tent.
:01:58. > :02:04.Yes, you heard me - we played the tent, live.
:02:05. > :02:07.But we weren't the only geeks at Hay, so we used the opportunity
:02:08. > :02:12.to meet and chat with some of the big names in science and tech.
:02:13. > :02:18.Almost 18 months ago, the quest to build the world's first commercial
:02:19. > :02:23.space line suffered a major setback after a tragic accident.
:02:24. > :02:36.After the accident in October 2014, a thorough investigation was
:02:37. > :02:42.undertaken by the NTSB, the US accident investigation board.
:02:43. > :02:45.They established over a period of six or seven months exactly what
:02:46. > :02:52.happened to cause the breakup of the spaceship.
:02:53. > :02:54.Having understood the causes of that accident, we have completed
:02:55. > :03:01.That was rolled out in Mojave a few weeks ago.
:03:02. > :03:04.We are completing ground tests of that vehicle and will be back
:03:05. > :03:06.into the test flight programme in a few weeks.
:03:07. > :03:08.When the original project was announced,
:03:09. > :03:13.the implication was you would be up and running within a short time.
:03:14. > :03:24.I think we have learned that space is hard.
:03:25. > :03:27.And particularly if you are building a vehicle
:03:28. > :03:30.which needs to fly many hundreds if not thousands of times
:03:31. > :03:37.with paying passengers on board who expect a high level of safety.
:03:38. > :03:39.None of that comes as a surprise to me.
:03:40. > :03:42.I would have thought that would be on the table from the beginning.
:03:43. > :03:46.We knew it was hard, but we looked at what was potentially possible,
:03:47. > :03:49.but as you get further into the project and you understand the true
:03:50. > :03:52.complexities and making sure you are not just delivering an extraordinary
:03:53. > :04:01.experience, but an extraordinarily safe experience,
:04:02. > :04:06.It seems to me if you were carrying freight
:04:07. > :04:09.to the International Space Station, you'd make a bit more money.
:04:10. > :04:12.Is that where you are going with this?
:04:13. > :04:15.Our focus to date has largely been on getting people into space.
:04:16. > :04:19.But we also recognise there is a huge demand right now for launching
:04:20. > :04:27.So satellites are getting smaller, smarter, cheaper and lighter.
:04:28. > :04:31.There is an insatiable desire for the data they can generate up there.
:04:32. > :04:32.But the cost and availability of launch
:04:33. > :04:38.It is one of these unusual industries which
:04:39. > :04:41.has proven itself to be incredibly important, but the technology used
:04:42. > :04:44.to get people and payload up there has not changed dramatically
:04:45. > :04:55.We are very focused on getting this first step right,
:04:56. > :05:11.but we also spend a little bit of time thinking what might come next.
:05:12. > :05:13.Another fascinating talk, this time from roboticist Fumio Iida.
:05:14. > :05:16.In his research he asks the question, why do robots,
:05:17. > :05:18.with all their processing power and sensors, still find it
:05:19. > :05:22.Especially when the animal world finds them the
:05:23. > :05:26.We are trying to learn how we make motion in an efficient way.
:05:27. > :05:29.We can walk for hours and hours without any problems,
:05:30. > :05:33.but if you want to make robots walk in a similar way they can only walk
:05:34. > :05:43.for 20 or 30 minutes and they run out of battery.
:05:44. > :05:46.He argues that even the robots we have seen that can walk well
:05:47. > :05:50.Instead, we should build bodies that are naturally balanced,
:05:51. > :05:53.that stay upright, and that move without any processing power.
:05:54. > :05:55.The amazing, jawdropping moment from your presentation was
:05:56. > :06:05.Can you explain for our audience the bit about the fish?
:06:06. > :06:09.So, this is an experiment done by researchers in the US, who made a
:06:10. > :06:26.fish dead from a brain perspective, so they anaesthetised it.
:06:27. > :06:33.If you put the fish on the table, it is just dead.
:06:34. > :06:37.As soon as he put it in a water flow it starts swimming.
:06:38. > :06:40.The reason is that to swim, the fish doesn't really need brain
:06:41. > :06:43.All it needs is a well-designed body in the right environment,
:06:44. > :06:46.and it reacts to the right stimulus from the physical environment.
:06:47. > :06:50.How hard is it to make a body that walks by itself?
:06:51. > :06:52.You showed a video of a body that walks by itself.
:06:53. > :06:58.You have to think about many different things.
:06:59. > :07:00.You have to think about the weight of the body,
:07:01. > :07:06.the weight distribution, the friction, dumping, also the shape
:07:07. > :07:11.Mechanically it is challenging to design,
:07:12. > :07:19.The robots that can handle the real world best certainly do
:07:20. > :07:27.The trick, of course, is achieving in the lab what Mother Nature has
:07:28. > :07:36.We are not the only ones working incredibly
:07:37. > :07:48.Lara has been out and about in the park playing with some animals.
:07:49. > :07:52.This week I am testing some gadgets that need a little bit of help
:07:53. > :07:57.I have been asking around the BBC for any suggestions
:07:58. > :08:03.and it seems that someone is meeting me here at midday.
:08:04. > :08:18.Pleasure's all mine, Cocker, Hacker T Dog here, star
:08:19. > :08:26.Here I am making my break-out presenting debut on grown-up telly!
:08:27. > :08:30.Normally, it is us humans who get the great gadgets to play with.
:08:31. > :08:33.This week, I have something for you guys, so I wondered
:08:34. > :08:39.There is even something to keep dogs fit and healthy.
:08:40. > :08:54.I think we might need to find a real dog.
:08:55. > :08:57.Whilst I go look for one, can you make yourself useful?
:08:58. > :09:11.This is like one of those human fitness track
:09:12. > :09:20.It is available for iOS, Android and Windows phone.
:09:21. > :09:23.You set it up in pretty much the same way you do
:09:24. > :09:26.any activity tracker, only you need to input the breed of dog,
:09:27. > :09:34.It should be able to tell you how much activity the dog needs to be
:09:35. > :09:41.getting and you can start tracking what it is actually doing.
:09:42. > :09:44.You can see how much activity the dog has been getting throughout
:09:45. > :09:48.the day, and if you want to look at what has been happening over
:09:49. > :09:52.the week, here is the full data, and you can tap on any day to get
:09:53. > :10:08.210 minutes of activity on Sunday, that was a busy day!
:10:09. > :10:11.This is an app that uses artificial intelligence to identify what breed
:10:12. > :10:17.It can give you a percentage like us to familiar breed and can tell the
:10:18. > :10:20.difference between a real dog and an inanimate object, like a cat!
:10:21. > :10:25.It was spot on for Truffle, and some other dogs are tested it on.
:10:26. > :10:29.But it wasn't so lucky when it came to Lucky's mixed breed.
:10:30. > :10:33.And just to add a totally pointless but compelling extra, or you can
:10:34. > :10:37.photograph friends and family to see which dog they most resemble.
:10:38. > :10:43.Although it did seem to think that Hacker was real.
:10:44. > :10:46.Ball Ready is a quirky combination of snack feeder and ball thrower.
:10:47. > :10:48.It can entertain your pet when you can't
:10:49. > :10:55.and you can select the quantity of food you wanted to provide.
:10:56. > :11:00.It can be used indoors or outdoors, and after firing out balls for the
:11:01. > :11:04.dog to fetch, it will reward them with snacks for returning them.
:11:05. > :11:06.Admittedly, it takes a bit of practice,
:11:07. > :11:10.but once they have got the knack it is a great way to wear them out.
:11:11. > :11:37.That is it for the short version of Click. The full version is mine. And
:11:38. > :11:39.next week we will be in China. Can't wait. See you there.
