PETMAN has to be the most physically capable humanoid robot in terms of flexibility, range of motion and robustness. It has been developed by
Boston Dynamics, the same people who created BigDog, and is intended to tryout military equipment. Check out this video in order to see the robot, walk, move and get kicked.

Kicking a full humanoid robot that has similar capabilities to a human soldier does not seem to be the wisest thing to do. Let's just hope PETMAN won't take it personally and that he is simply Stayin' Alive.
