ICYMI: How #SouthKorea's DRC-HUBO #Robot won the #DARPA #Robotics Challenge

Professor Oh said that, for many tasks, especially climbing stairs, it’s important that the robot is able to see its own feet. Big robots like ATLAS have a hard time doing that, having to bend their bodies and making balancing more difficult. DRC-HUBO solves this problem in a very clever way. It climbs the stairs backwards ! By doing that, its knees don’t block the robot’s cameras from seeing its feet and the ground, and another advantage is that its shins won’t ever hit the steps when it bends its legs. But how does it see its own feet if it’s climbing the stairs backwards? By rotating its upper body, of course! You can see the process starting at 0:26. The robot is kneeling in front of the stairs when it suddenly turns its back to it. It then stands up and at 0:55 you can see it turning the torso 180 degrees. Now it can scan the stairs and start the climb. But note that,...
