To drop an investigation into links between his Election Campaign team and russia. Now on bbc news, its time for click. This week, preparing for the worst in vr. A bunch of new apples. And the bouncy, strokey, stretchy, bendy, slimy world of Soft Robotics. It is hard to believe that the world is safer than it used to be. It is, but the nature of the Terror Attacks in the west in the last few years the increasing use of vehicles, knives and guns to carry out prolonged attacks, have forced the authorities to think differently about how to deal with a terrorist incident. And of course, theyre not confined to the west. In some parts of the world, these atrocities are more common and often have more casualties. Its difficult to predict when and where a Terrorist Attack will occur. But while the authorities cant predict, they can prepare for the worst. This is a large scale counterterrorism training exercise. It was a combined effort, including londons metropolitan police, fire and ambulance and river services. However, training on this scale is expensive and requires large numbers of personnel and huge amounts of planning, so it cant happen that often. But there are new ways to train more people individually. Marc cieslak has been taking part in a new type of terror training. Since 2015, from all across europe, a group 01 14 partners, including law enforcement, Emergency Services, Transport Companies and universities, have been working together on a three year project to create Training Simulations for real world Terrorist Attacks, using Virtual Reality. Part of it has been designed here at Sheffield Hallam university. Rather than build new technologies from the ground up, the hardware and software that is at the core of this Training System is tech that is more commonly found in video games. And that technology is proving to be a flexible training tool. You can act out a lot more scenarios that would be too dangerous to do in any real life setting. Its a lot cheaper, its more cost effective, its easier to set up, and it offers a whole range of scenarios that you couldnt do in real life, because they would just be too dangerous or too complicated. Its a big project. Virtual simulations that can be used to train a wide variety of different people, from paramedics to the police, and even those employed by the transport networks. For this scenario were going to put a new bag down here. There we are. A suspect bag has been placed in an accurate virtual model of a real location a Subway Station in the spanish city of barcelona. My task as a trainee is to find it. Ok, so im on the platform. I can see people. I cant walk into them. Now i can see a package over there. I can interact with the bag. Ill press this button here. The bag opens. There is what im assuming is some kind of explosive with wires plugged into it. So in this situation im going to start evacuating all civilians in the immediate area. Im going to tell them to start to evacuate. Start evacuating but all doesnt go to plan. Now your people are evacuating towards the bomb, which you dont want. So you might want to go on the platforms to start evacuating people in the correct direction. So all of the passengers are all being driven by an ai, yeah . Yes. But the people behave in a pretty realistic fashion . Yes. Start evacuating thats all based on Scientific Data of what people do in real situations. So youve successfully started evacuating everybody who has been on all the platforms. Next, a different scenario. We cant show too much of this as the images are just too graphic. In the aftermath of an explosion, a Paramedic Trainee must triage the injured passengers, applying different coloured stickers to a passenger. The different colours indicate the urgency of the requirement for treatment. Its an unsettling and distressing experience. It is meant to be, though. Overwhelming sound and distressing images are designed to replicate real world situations. But this system isnt just the work of Counterterrorism Researchers and software engineers. To find out more, i travelled to the real location featured in the simulation. In recent years, terrorist atrocities have been carried out all over europe, highlighting the International Nature of the response to this terrorism. Here in barcelona, the Emergency Services themselves have played a key role in the design of the auggmed Virtual Reality simulation. Josejurado is a doctor and emergency First Responder here in barcelona. Hes been helping to fine tune the system to improve its utility to Emergency Services and paramedics. So this is the station that i saw in the vr model . Yes. What is the big thing that you get from the Virtual Reality, from the fact that it is so immersive, that you are thrown into a Virtual World . When i get to a real situation, i am used to it, i am trained for it. So it doesnt surprise me so much as it could. It is quite unusual being in the real station, having spent a little bit of time in the virtual version. What has been interesting Walking Around here is noticing i now know the layout, the geography of the station. I know where all of the exits are, i know where the escalators are, and which Direction Of Travel they go in. So even i was able to learn something very, very quickly in that Virtual Reality version of this Subway Station. But vr has its limitations. Robert guest is from Birmingham University and is part of the auggmed development team. You cant really get a physical hands on an object in Virtual Reality, but what we can trade is things like decision based training. We can look at emotional management and general Communication Skills between Different Team members. We see terrorists constantly changing their tactics. How do you guys respond to those changes of tactics . The benefit of this project as a whole is we can rapidly change what scenarios are actually being trained. So for new tactics being used, out in the public, in reality, for those situations very rapidly. The next stage of this Systems Development is a haptic vest, which provides Force Feedback to trainees simulating physical sensations. Its also fitted with heating elements, which make the trainee hotter. If you are in a stressful environment like this one, there is a good chance you will start to get hot and sweaty. As soon as you get uncomfortable, then that makes it a lot more difficult to do yourjob and creates an environment for them which is as close as it can be to the real one. This whole system isnt designed to replace real world training but to augment it, to allow people to betray dramatically if need be, constantly reinforcing their skills. Skills which recently have been sadly tested all too often. That was marc cieslak. Now, while the professional First Responder is always going to be better trained, it is ask the public who are almost always going to be first on the scene of an attack. Current advice from the British Police is to run from an incident, rather than surrender or try to negotiate with attackers. This online video also explains how and where to hide if you cant escape. Now, if you dial 999, but it is not safe to talk out loud, the operator will give you the option to dial 55, to show you havent called by accident and you really do need help. 55 looks like ss, which stands for silent solution. There is also an app called citizen aid, which uses advice from combat situations to help users administerfirst aid and make more informed decisions in different emergency situations. Hello and welcome to the week in tech. It was the week that uber refunded customers for journeys taken near last saturday nights london Terror Attacks, after pricing had automatically surged due to demand a function they disabled later that evening. The Comment Section on Britney Spears Instagram Account has been used by russian Speaking Hackers to test malware. And snapchat specs have gone on sale in the uk. If you think this is a sensible way to go out. Googles Streetview Cars have been tracking air pollution. After a year of the vehicles driving around the streets of oakland, california, data localised to individual roads has become available, with initial recordings of black carbon, nitric oxide and Nitrogen Dioxide being revealed. Anyone with kids can tell you what its like trying to get play doh out the carpet. But, sadly, i dont have a new gadget to tell you about that. Its actually the play clay thats gone high tech. Doh universe can conduct electricity and aims to help kids learn about circuits, sound, light and movement through play. And, finally, researchers at mit have developed sensors for the grippers of robotic arms that aimed to help bots grab things with the right amount of pressure. The Gelsight Sensors Aim to make negotiating smaller objects possible, as well as making General Household tasks easier to approach which would be handy, if one day robots are to become ordinary household companions. This annual running of the nerds can only mean one thing. We are in sanjose for apples Worldwide Developers conference, otherwise known as wwdc. Its an event the company doesnt typically used to make big product announcements, but, this year, perhaps feeling the heat a little, they broke with tradition and revealed a bunch of new stuff. Its been 15 years since we held the Developer Conference in sanjose and an awful lot has changed. The homepod is a direct competitor to assistance made by amazon and google. It will cost 349 and be available later this year in the us, uk and australia. Other countries will get it in 2018. It will be controlled by siri, but apple isnt really calling it a home assistant. They say it is a music device first and foremost. We werent allowed to film it in action, but i was given a private listen and, well, it does sound fantastic. One of the potential downside is that you need an apple Music Subscription in order to get the full integration. So if you prefer to use spotify or pandora, maybe not quite the device for you. In other news, apple says it can become the biggest Augmented Reality Platform overnight. This demo is from the new production house run by peterjackson, the man famed for creating the lord of the rings movies. And the ipad has been given a new lease of life. They announced a new 10. 5 inch ipad pro and the next version of apples Operating System will see the tablet get a bunch of extra features. Many people might see this as a kind of middle ground between getting a very expensive computer, but still being able to get their work done. Several thousand developers turn up to wwdc every year. Many more would come if they could get tickets. Among the masses, ifound the youngest attendee, a ten year old who had come all the way from melbourne, australia. I just enjoy the fact that i can turn, like, my ideas into reality by programming and making apps. So this is my most recent app, which i published six days ago. You can click anywhere to place a block. Your goal is to get the highest tower blocks. So you are obviously much younger than everybody here . Yes. So what do you want to do when you grow up . Are you going to carry on making apps . I want to be a turtle. You want to be a total . Im joking i mean, why not. I dont know. How can ijust turn myself into a turtle and grow a shell . And become green. Iamjoking. I would like to create apps i can revolutionise the world. And i also want to teach the world coding and get them into coding, so they can actually improve all the technology we have and make technology a whole lot better. A young man destined for great things, im sure. Think robots and maybe youll picture Something Like this. Or this. But what about robotic muscle and smart materials that could act as human skin, all clothes that rehabilitate you as you wear them . Well that is part of whats called Soft Robotics and this team at Bristol Robotics Lab are bioengineering technologies to do all of that and more. I went to take a peek at their labs. This is a bucket of alien saliva, right . Yeah, this is the same stuff that drips out of the alien mouth. So ridley scottjust used a whole bunch of that. Though, in this case, it is to simulate blood. This soft robot mimics how some bacteria move through our bodies. In the future, it is thought that nano robots will take a similar trip through our veins looking for infection and illness. Oh, thats awesome some of the projects they are working on here involves making Assistive Technology for elderly and disabled people, like this pneumatic artificial muscle. It can be made into any shape and built into clothing. As you apply air, it changes its shape so it could for instance help people with limited grip strength. Its forces only dependent on how much air pressure you apply. And here is some material that can sense when that pressure should be applied. This Diametric Elastomer can detect when its being stretched, so it can sense when you are trying to move and add extra power to maybe help you up the stairs. And it can not only detect movement, it can also change its shape when you apply a high enough for teach. You could use it for changeable clothing, clothing that can change its colour. You can use it as a sort of second skin to help with deep vein thrombosis, to assist with pumping blood. It can even be layered up to create stronger artificial muscles. It doesnt seem like it is doing a lot, but, actually, it is very thin, it weighs almost nothing the active part of which only weighs, lets say, four grams, and it can lift two kilos. In one respect none of this is complicated, none of this is extremely high tech, using like billions of transistors, and it is simple voltage and a piece of material. I think that is one of the big advantages of Soft Robotics, the simplicity, redundancy. In a complicated robotic system you have a lot of elements that can go wrong. With these sorts of things it is very simple and it is very adaptable. The intelligence is in the design and immediately used, rather than in the complexity. The robotics lab in bristol is 50,000 square feet of innovation filled with hundreds of different types of robots. But what nearly all have in common is they need power to run. Over in the bio energy lab, scientists are working on one freely available re source the world will never run out of urine. Each one of these cylinders is a microbial fuel cell device. It turns waste water into electricity using microbes. So the microbes eat the waste . They eat the waste. That is their favourite item on the menu. Right, ok ive been to that restaurant, yeah. In this unit, two litres of urine is fed into the fuel cell pack. The microbes eat what they need, creating electrons as a by product. And because they are attached to an electrodes surface, it is all collected to produce about 30 110 milliwatts of power. Now thats enough to slowly charge a smartphone, power smart displays, or power internal lights for their special portable toilets. This is only one unit of many. When we do it out of the lab, we install these units out of the lab, we have many more of them connected together as a stack. If you are going to glastonbury this year, you might see these screens near the urinals. If you choose to use the urinals, youll be part of an experiment which is literally putting the p into power. These are e ink displays, which dont require a lot of power. But a lucky few may be able to charge their phones for a bit, but only after donating. Most of the pee used here comes from staff donors at the lab. Its only good for the microbes foran hourorso, so a constant supply is needed. Although, i think ill hang on. Around the world, scientists are looking at different ways of improving our quality of life. Here, it is alternative sources of power. At Soft Robotics, its smart materials and possibly in the future bionic limbs. But in italys Scuola Superiore santanna, they are looking at sensation. Ana matronic went there to look at attempts to simulate touch. I am at the Biorobotics Lab where researchers are trying to merge human physiology with machine engineering. The team are working on a Bionic Fingertip that is capable of detecting texture. The human sense of touch is an incredibly complex one. I dont even need to look at these three pieces of plastic to sense the differences in the coarseness of the ridges. This of course presents a huge problem to people designing artificial limbs. How do you transfer that same sensitivity into a prosthetic hand . To create a machine capable of sensing and transmitting tactile data, first we need to understand how bodies decode sensory stimuli. Fingertips have the highest concentration of sensation almost anywhere in the human body. Thanks to 20,000 nerve fibres on each finger. And these tiny receptors. They react to sensory information as we move our fingers across different surfaces. Each receptor has a different role. Some respond to pain, some to temperature. Others react to pressure or vibration. This is the characteristic that allows our skin to interact with the environment and that will allow an object, when manipulated, not to break. The Bionic Fingertip registers the textures it touches as electrical spikes. On screen it may look simple, but that is exactly the language that our Nervous System speaks. As we touch objects, it sends Nerve Impulses to the brain. And the tiny, subtle variations in how the skin deforms as we touch changes those impulses and how we perceive texture. This capitalises on an actual principle and can be more effective as humans and animals in general can interact with the environment. The professor and his team have already had some success. Dennis sorensen was one of the first amputees to try out the Bionic Fingertip. The output from the finger was directly connected to the healthy nerves in his upperarm. I could tell the difference between where it was very rough and smooth. Yeah, that was amazing. And, since this first Clinical Trial a couple of years ago, the team had been trying to increase the number of textures the patients can feel. The experiments that we are showing now are demonstrating the capability to encode, for examples silk, from cotton, from elastic, from wool, from different kinds of materials. And in this way we could restore a more natural sense of touch to the person wearing the prosthesis. What is learned here can be transferred to other applications. For example, a surgical robot could use this technology to identify tumours, which would feel different in texture to healthy tissue. Another kind of application is for rescue. To allow robots to be present in the environment, not only through vision, but to have more senses available when exploring an environment. Think for example of the nuclear disasters, or in the case of underwater application. The robot can go and touch in the perceived environments, based also on the sensory feedback that you can have remotely controlling their arm. Once this technology is mastered, it can be integrated into simple things like gloves. For instance, i could be anywhere in the world. My husband back in new york can give me the sensation of petting our cat. And that would be transferred through these actuators to me anywhere in the world. I want one right now. Well i cant give you that at the moment, ana, but in the meantime, how about a hug from this chap . Thats it from the Bristol Robotics Lab. Next week, we are going to be in los angeles for the annual e3 video games extravaganza. It is going to be brilliant. We will tweet everything we see at bbc click. You can also follow us on facebook for loads of extra content throughout the week. Thanks for watching and we will see you in la. Hello there. Well start with a quick look at the latest satellite sequence, which shows a swirl of cloud out to the west of the uk. Thats the centre of an area of low pressure, and its weatherfronts have been drifting away across the uk, bringing some rain, but never really got to the south east corner. Its been a lovely afternoon here, with some sunshine and some warmth, as confirmed by one of our weather watchers in east sussex. Underneath that cloud, well, heres a picture from wales, and it shows rain on the windows. There has been some rain stretching from Northern England to wales to the south west. I think Northern England will tend to dry up and that patchy rain will drift its way through the midlands, very light and patchy by this stage. Behind it, some dry spells, but there will be a few showers in scotland and in Northern Ireland. But temperatures probably no lower than 1a or so degrees for glasgow and belfast. Some parts of the south east probably no lower than about 16 or 17 degrees, so quite a close night here. Into the morning then, scattered showers across scotland and Northern Ireland. And already at nine oclock, weve got 15 degrees on the eastern side of scotland, where there should be some dry and bright intervals. And its a mostly dry picture across Northern England, through wales and the south west, in the morning. Variable cloud and a little bit of sunshine. There might be a shower or two in the south west, but i suspect most places will be dry. A fair bit of cloud for the east midlands, east anglia and the south east. There may be a little bit of light rain and drizzle, but at nine oclock, weve already got 17 or 18 degrees. As you go through the day, it will stay pretty cloudy. East anglia and the south east, a little bit of light rain and drizzle on and off. Well see some spells of sunshine behind there, but scattered showers get into the western side of england and wales. The showers across scotland and Northern Ireland will be quite frequent. And it wont be quite as warm as it was today. 16 or 17 degrees in glasgow and belfast. This little weather feature might be a focal point for some wetter weather in western scotland. One or two showers elsewhere, but a lot of dry weather. And the winds slowly easing down. There will be some spells of sunshine to be had on monday, and well see temperatures getting up to the low 20s in the south eastern corner, but for many places, it will only be the middle teens. Then looking ahead towards the tuesday, and High Pressure continues to build in across the uk. Still got these weather fronts, just a glancing blow, really, towards the north west of the uk. So the closer you are to the north west, the more likely you are to see at least some cloud. Youre watching bbc news. Im jane hill at westminster, where the prime ministers top advisers nick timothy and Fiona Hill Have resigned. Nick timothy sad he regretted not including a pledge to cap total social care costs, and that the party hadnt talked to the people who decided to vote labour. They went following what the bbc understands were demands from some conservative mps that mrs may would face a Leadership Challenge if didnt go by this weekend. I dont see how theresa may can function properly without them. They we re function properly without them. They were almost right and left arm, and she has made a huge sacrifice in order to continue. Mrs may is preparing for talks with the democratic unionist party
