Balancing Robot Can Take a Kicking

BotKicker writes "A Japanese team has created the first full-size humanoid robot that won't fall over if you push it. A video shows it staggering and regaining balance after blows from a researcher. Being able to withstand shoves and kicks is essential if robots are to truly be our buddies, they reckon. 'The robot's balancing ability depends on its joints. For one thing they are never kept rigid, even when standing still, meaning they yield slightly when the robot is pushed. Force sensors within each joint also work out the position and velocity of the robot's centre mass as it moves around. Control software rapidly figures out what forces the robot's feet need to exert on the ground to bring it back into balance, and tells the joints how to act.'"

Been done

I saw a show on the Discovery channel over a decade ago showing a one legged robot that could recover it's balance when kicked.

Loaded fine for me. Here's the coral cache version of the video [nyud.net] if you are still having problems.

I doubt the point is for the robot to be impossible to knock over, just for it to have a similar sense of balance to a human. The next step, if I may hazard a guess, would probably be testing to see if it can maintain it's balance while walking along uneven surfaces, stairs, sharp inclines, etc. Also important would be its ability to return to a standing position if a random Slashdotter gives it a full-force, running, midair knee-extension kick.

I wrote about the i-1 on my blog; there's some pictures there that might be interesting.

Whenever someone pushes me, I always push back. It's the law. (Newton's third, to be precise.)
