:00:00. > :00:00.hour. Will keep you up-to-date with all these deliverance. Let's pause

:00:00. > :00:00.for a fume and it's a catch up with the latest technology to bromance.

:00:00. > :00:38.He is clicked. Think robots and maybe you'll

:00:39. > :00:44.picture something like this or this. But what about robotic muscle and

:00:45. > :00:50.smart materials that could act as human skin close that the as you

:00:51. > :00:57.wear them? That is what is cold soft robotics and this team at Bristol

:00:58. > :01:00.Robotics lab our engineering technologies to do all about and

:01:01. > :01:09.more. I went to take a peek their labs. This is a bucket of alien

:01:10. > :01:14.saliva. This is what drips out of the alien mouth. Ridley Scott just

:01:15. > :01:19.used a whole bunch of that. In this case it is to simulate

:01:20. > :01:23.blood. This soft robot mimics how some bacteria move through our

:01:24. > :01:27.bodies was up in the future it is thought that nano robots will take a

:01:28. > :01:33.similar trip to our brains looking for infection and illness.

:01:34. > :01:41.That is awesome. Some of the projects involve making assistive

:01:42. > :01:44.technology are elderly and disabled people like this pneumatic

:01:45. > :01:48.artificial muscle which can be made into any shape and built into

:01:49. > :01:54.clothing. As you apply it changes its shape so it could for instance

:01:55. > :01:58.help people limited grip strength. It is dependent on how much error

:01:59. > :02:04.pressure you apply anti-some material which can sense when that

:02:05. > :02:07.pressure should be applied. This diametric elastomer candidate when

:02:08. > :02:11.it is being stretched so it can sense when you try to move and add

:02:12. > :02:16.extra power to maybe help you up the stairs. And it can not only detect

:02:17. > :02:22.movement, it can change shape when you apply a high enough voltage.

:02:23. > :02:25.You could use it for changeable clothing that contained its colour.

:02:26. > :02:28.You can use us as a sort of second skint to help with deep vein

:02:29. > :02:34.thrombosis and assist with pumping blood. It can even be layered up to

:02:35. > :02:38.create artificial muscles. It does not seem to doing a lot but actually

:02:39. > :02:43.it is very thin and weighs almost nothing. The act apart only ways

:02:44. > :02:46.like say four grams and it can live two kilos. None of this is

:02:47. > :02:52.complicated. None of this is extremely high-tech using billions

:02:53. > :02:57.of transistors. It is simple voltage and a piece of material. I think

:02:58. > :03:01.that is one of the big advantages of soft robotics. Simplicity. In a

:03:02. > :03:04.conjugated robotic system you have a lot of elements that can go wrong

:03:05. > :03:07.and with the sort of things it is very simple and it is very

:03:08. > :03:14.adaptable. The intelligence is in the design and immediately useful

:03:15. > :03:19.rather than the complexity. The Robotics lab in Bristol is a 50,000

:03:20. > :03:24.square feet high of the innovation filled with hundreds of different

:03:25. > :03:30.types of robots but what nearly all have in common is they need power to

:03:31. > :03:33.run. Over in the bioenergy lab scientists are working on one freely

:03:34. > :03:40.available resource the world will never run out of. You're in. Each

:03:41. > :03:45.one of the cylinders is a microbial fuel cell device. It turns waste

:03:46. > :03:50.water into electricity using microbes. So the microbes eat the

:03:51. > :03:56.waste? They each the ways. That is their favourite item on the menu.

:03:57. > :03:59.Essentially. I have been to that restaurant, yeah. Two litres of your

:04:00. > :04:04.lunar spread into the fuel cell power. The microbes eat what they

:04:05. > :04:08.need, creating electrons as a by-product. Because they are

:04:09. > :04:13.attached to an electrode surface it is connected to the dues about 30 to

:04:14. > :04:18.40 minute watts of power. That is enough to slowly charge a smartphone

:04:19. > :04:24.or power internal lights for their special portable toilets. This is

:04:25. > :04:29.one use of many. And we do it out of the lab, when we install these units

:04:30. > :04:34.out of the lab we have many more of them connected together as a stack.

:04:35. > :04:39.If you are going to Glastonbury this year is you might see these screens

:04:40. > :04:43.near the finals and if you choose to use the rhinos then you'll be part

:04:44. > :04:52.of an experiment which is literally putting the P into power. These are

:04:53. > :04:59.displays which don't require a lot of power but a lucky few may be able

:05:00. > :05:04.to charge their phones for a bit. It only after donating. Most of the P

:05:05. > :05:08.used here comes from staff donors at the lab. His only good for the

:05:09. > :05:19.microbes for an hour or so saw constant supplies needed. Although,

:05:20. > :05:23.I think I'll hang on. Welcome to the week in Tech. It was the week that

:05:24. > :05:33.Goober refounded customers for journeys taken near last Saturday

:05:34. > :05:42.night's terror attacks after surging demand. Upload is launching a voice

:05:43. > :05:47.controlled speaker. The comment section on Britney Spears's Insta

:05:48. > :05:53.gram account has been used by Russian speaking hackers. If you

:05:54. > :05:58.think this is a sensible way to go out, anyone with kids can tell you

:05:59. > :06:05.what it is like trying to get play dough out of the carpet but Serbia

:06:06. > :06:11.do not have a new gadget to tell you about for that.

:06:12. > :06:17.This aims to help kids learn about light, sound and movement to play.

:06:18. > :06:25.And finally, researchers at MIT have developed sensors for robotic arms

:06:26. > :06:29.that aim to help bots grab things with the right amount of pressure.

:06:30. > :06:32.The aim to make negotiating smaller objects possible as well as making

:06:33. > :06:37.general household tasks easier to approach. This would be handy if one

:06:38. > :06:45.day robot are to become ordinary household companions.

:06:46. > :06:48.Around the world scientists are looking at different ways of

:06:49. > :06:53.improving our quality-of-life Auster pierces alternate sources of power.

:06:54. > :07:03.Soft robotics, and possibly in future bionic limbs. But in Italy's

:07:04. > :07:08.liability at other things. They are looking at simulating

:07:09. > :07:10.touch. Researchers are trying to merge

:07:11. > :07:15.human physiology machine engineering. The team are working on

:07:16. > :07:22.a bionic fingertip that is capable of detecting texture. The human

:07:23. > :07:28.sense of touch is incredibly complex one. I don't even need to look at

:07:29. > :07:38.these three pieces of plastic to sense the differences in the ridges.

:07:39. > :07:52.How do you transfer that same sensitivity into a prosthetic hand?

:07:53. > :08:00.Fingertips have a higher concentration thanks to 20,000 nerve

:08:01. > :08:38.fibres on each finger. It registers textures its touches as

:08:39. > :08:41.spikes. On-screen it may look simple but that is exactly the language

:08:42. > :08:47.that our nervous system speaks as we touch objects, it sends nerve

:08:48. > :08:52.impulses to the brain. The tiny subtle variations in how the skin

:08:53. > :08:58.deforms as it is touched changes those impulses and how we perceive

:08:59. > :09:01.texture. This capitalises on the natural

:09:02. > :09:06.principle and so can be more effective as humans and animals in

:09:07. > :09:09.general can now interact with the environment.

:09:10. > :09:15.The professor and his team have already had some success. Dennis was

:09:16. > :09:18.one of the first amputee to try out the bionic fingertip. The output

:09:19. > :09:23.from the finger was directly connected to the healthy nerves in

:09:24. > :09:31.his upper arm. I could tell the difference between the way it was

:09:32. > :09:37.very rough and smooth. Yet, that was amazing. Since those first clinical

:09:38. > :09:42.trial cup of years ago the team have been trying to increase the number

:09:43. > :09:50.of textures that patients can feel. The experiments that were showing

:09:51. > :10:00.now are strengthening the capability to tell silk from cotton, wool from

:10:01. > :10:05.different kinds of materials. And in this way we can restore a more

:10:06. > :10:09.natural sense of touch to the amputee that is wearing the press he

:10:10. > :10:12.says. What is learnt it can be transferred

:10:13. > :10:15.to other applications, for example a surgical robot can use this

:10:16. > :10:20.technology to identify tumours which would feel different and texture to

:10:21. > :10:24.healthy tissue. Another kind of application is for

:10:25. > :10:31.rescue, so to allow robots to be present in the environment not only

:10:32. > :10:33.to listen, but to add more sensors available when exploring and

:10:34. > :10:39.environment. Think example of a nuclear disaster, so in the case of

:10:40. > :10:45.underwater application the robot can go and touch and perceive the

:10:46. > :10:51.environment based on the sensory feedback that you can have remotely

:10:52. > :10:55.controlling the robot. Once this technology is mastered it

:10:56. > :10:58.can be integrated into simple things like gloves so for instance, I could

:10:59. > :11:04.be anywhere in the world, my husband back in New York can give me the

:11:05. > :11:08.sensation of petting our cat and that would be transferred through

:11:09. > :11:15.these actuators to me anywhere in the world. I want it right now.

:11:16. > :11:19.I can't give you that at the moment but in the meantime how about a hug

:11:20. > :11:23.from this chap? That's it for the short cut of kick from this week.

:11:24. > :11:27.The full-length version is on IP right now. Next week we're going to

:11:28. > :11:36.Los Angeles for the annual video games extravaganza. Is going to be

:11:37. > :11:37.tweaking every thing that we seem. Follow us on Facebook. Thanks for

:11:38. > :11:48.watching.
