faces on the dormant bench said it all from too no luck they found themselves back wished for. by and remain at the top of the table thanks to the man who can seemingly rescue them from any situation. you're watching d.w. news up next our technology show shift stay tuned for that i'm michael okuda thanks for joining us. i'm secure in that my work that's hard and in the end this is a me you are not a lot of the year and more we will send you back. are you familiar with this. with the smugglers were lions of the what's your story ready.

for far too long. radiation sickness has many different effects seizures controlled pleading. burns and blisters. it can even lead to bone marrow failure even today anyone who ventured too close to fukushima is reactor core wouldn't survive long. 10 years after the triple core melt own radiation is still extremely hazardous today some 7000 people are working on decommissioning the power plant but due to high contamination they are only allowed on site a few days a month on march 11th 2011 a tsunami struck japan's coast and caused the nuclear plants to fail but how can we clean radiation zone becomes even access. with robots. but it's actually not that simple not even all robots can withstand the radiation they're exposed to in fukushima disaster zone but more and that's later energy provider tepco in tech giant to shiva teamed up to develop robots that could help clean up fukushima's

radioactive rooms the challenges they have to face are relentless some pass the test others not quite here are 3 of the most exciting robots from the last decade. one of the biggest questions in the fukushima cleanup remains. where to start. parts of the buildings were destroyed when the reactor exploded the blast caused walls and floors to collapse and reduced sensitive equipment to twisted hulks of metal the situation varies in each building but over consumption ated when radioactive material was vented from the reactor containment vessels. this is where so current and rosemarie come into play the robots joe was developed in 2015 to inspect the buildings but that's easier said than done some floors can only be accessed through extremely narrow and steep stairways no simple feat for robots but

that's exactly what rosemary and security were built to do. in addition rosemary was fitted with a gamma camera that can detect and display radioactivity. you can see that here in the colored images the recordings were to be shared on a wireless network and that's when engineers faced the next challenge. nuclear power plants are designed with a number of safety measures and built to withstand extreme conditions. wireless signals barely make it through the thick concrete walls of the reactors that's where scurrah comes in the robot functions as a signal transmitter and helps rosemary relay its recordings to the outside world. both robots were partially successful in their mission they enabled authorities to get their 1st overview of the reactor after the fall out. the scorpion was the great hope for fukushima and 2017 it was meant to inspect the

spots where radioactive lever 1st elite out of the reactor vessel joining the 2011 disaster the nucular fuel rods had heated up to 1200 degrees celsius causing them to melt through their metal casings the japanese government invested a lot of money in developing this little robots it was named for its appearance the cameras mounted on a retractable arm that hangs over the robots body like a scorpion stale it was tested and improved for months until it was tiny enough to squeeze into the containment chamber. the only way to get inside was a 14 centimeter wide hole in the concrete wall created just for the robots but before the scorpion could set out on its mission in units to the exploration suffered major setbacks one week prior to the robots designed the clear the way for the scorpion failed its comrades the cold and to the extreme radiation.

nevertheless the scorpion was slated to deploy unlikes occur and rosemary wireless data transfer wasn't an option because the robots had to crawl to deep instead it was left dragging a heavy cable along if successful it would locate the radioactive waste that had leaked out of the reactor vessel so it could be salvaged in the future. everything went smoothly at 1st. the scorpions recordings were transmitting with i would say hitch. and it was getting ahead well. but then. just 3 meters before states the nation the scorpion simply stopped what happened we still don't know for sure maybe it got stuck or maybe the radiation was too much to handle. in the end the researchers decided to cut the scorpion loose and abandon the mission sorry little guy.
10:22 am
after the scorpion had failed researchers had to come up with another solution to find the leaks material they gave up on units 2 for the time being and concentrated on reactor 3 instead but there are a whole new set of challenges lay ahead when the reactors exploded in 2011 for containment chambers were flooded to cool the reactors of course the perfect part would have to be small enough to maneuver through a tight hole in the wall strong enough to drag along a cable that could transfer images and survive as an emergency rescue line up and swim. quite a tall order but the japanese engineers found a compact solution little some fish after losing the scorpion they weren't taking any more chances they tested little some fish for months in lab pools fitted with a camera and a tiny propeller powerful enough to navigate it through the dark van it was time to send little sunfish out. the mission was nerve wracking. a pilot student through the water with a controller reminiscent of
10:23 am
a video game. on day one none of the material transmitted was any good. but then on the 2nd day of the mission the little robots bumped into a waxy mass on the floor of the containment chamber the radioactive core had congealed into a solid lump and dropped to the bottom of the floated structure success. is now secure a rosemary scorpion until some fish were just a few of the robots built to understand and repair the ruins of fukushima in the last 10 years their main objective was to explore thanks to them we have a rough idea where the radioactivity is highest and where the radioactive waste has settled in the coming years the challenge will be to. covered this waste here 2 robots will be dispensable robo diggers are already being tested for their missions in the hopefully not too distant future.

japan lies along the ring of fire making it a hotspot for natural disasters to save lives researchers are developing new rescue technology. made the snake bot its 36 joints make it incredibly flexible. this lets it we go across tough terrain slither through pipes and even climb a ladder should disaster strike the snake robot could be a lifesaver it's been developed by a team of researchers at kyoto university. they can i took it all 1st of all these robots are used in places humans cannot enter or where it's not sure whether it's safe to enter. the robots can help to measure of the concentration or c o 2 levels. of the vatican hope to evaluate whether rescue workers can be sent in.

to a tomato who got the call this or the new year how can we not consider places that may be in danger of collapsing but that occluded our robots can go in and gather information. so in broad terms these robots unable access to places where it's too dangerous for humans to enter. the united will hide these are applications where robots can play an active part concepts about whether surgical procedures for everyday situations snakes have often served as models for industrial design their flexible bodies are the perfect blueprint for agile robots. save in the heavy sticks are interesting creatures that can move without legs that's the 1st aspect about this mysterious. animal that makes my curiosity. to see not go to war mop aim isn't simply to imitate snakes. we want to create

a snake like inspired robots that's better to slinks. who. are sleek robots can climb of ladders and has a very uneven slick surface and the more there are no protruding cords the can slip into the wall but wouldn't cover the door which will fit into each other with the door caught small so many because i can change of too close on the cormo that is unless it bends and will still move smoothly because so you designed it and that is vital to any rescue missions japan is prone to natural disasters earthquakes are common in the country must be prepared for typhoons tsunamis and mechanical rupture ever since the kobe earthquake in 1905 let's you know it's been developing technologies to help to. to deal with the end of that that so regionally i worked on space exploration robots. but then one of my students died in the great hunch an

earthquake. that's when i decided to focus my research on the suster and response robots. go the snake that is operated using a controller and comes equipped with a camera and numerous sensors engineers considered many different scenarios when creating the robot for instance when searching for survivors after a natural disaster the bot might need to be able to climb up a pipe. outside or inside. ladder. or even slip their it's way through pike. courage to ask you to use who will at 1st i wanted to create robots that rescue people hope. but then i changed my mind. when disasters

strike an urban area it's incredibly hard to find victims buried under the rubble when you go out on the net. as to when the rescue workers will dig around here and there we don't have much success at all to know how to what's going to trial and error process that's wastes a lot of valuable time during which people want to donate not this month but the student. for me tashi matsunaga also designed this rescue robot the prize winning. its 4 legs and tank like trads let it go places humans can't a multi functional arm effortlessly opens doors and retrieves objects. these robots are still under development but soon they could be sent out on rescue missions and help save lives.
