DARPA's new "Pet-Proto" robotcan avoid obstacles and climb stairs

A few days ago, DARPAtv (the youtube channel for DARPA) uploaded a video showing off their latest robot named Pet-Proto. The robot was given the challenge of climbing stairs and avoiding a huge gap in a given path. With all the new technology that was out into this robot, it was able to climb the stairs with little effort. It also got past the gap by spreading it's arms and legs to grip the nearby wall to traverse right through. All these tasks were achievable because of Pet-Proto's specially designed legs. If your interest in this bot, then check out the video above!
