This is a real-life Transformer (OmniZero.9, the brainchild of Takeshi Maeda) that can morph from a humanoid robot to a humanoid robot that can carry a person, to a wheeled cart. Just watch how scary it is when it moves. If I didn't know better, I'd swear there was a little person in there. But there isn't! Just wires and servos and a metallic heart of death. Which, true story, only beats for the destruction of the human race. And speaking of which: One time I competed in a three-legged race solo.
Hit the jump for a video of the robot battling another, much smaller one.

Thanks to Michael, who once won a four-legged race because he was raised by wolves.
