MIT, Cornell and Delft University of Technology projects are attempting to build simple robots that walk like humans.

MIT's Toddler is a robot that mimics the gait and control of human walking. Through software it can teach itself to walk in less than 20 minutes, or about 600 steps.

Researchers at the Delft University of Technology in the Netherlands have built Denise, a robot that walks with two legs. It has knees, an upper body, and two counterswinging arms. Its ankles help with stability.

Cornell University researchers claim their biped walking robot is "at least 10 times more efficient than anybody else's." They say it uses about the same amount of enery as a human--as opposed to Honda's Asimo, which uses 10 times more energy than a walking human.

This basic walker has only a passive joint at the hip. The curvature of the feet allows it to keep its balance and walk down a small incline.

This little headless, two-legged robot was built with Tinkertoys and developed at Cornell in 1998. It can walk, wobble and stagger, but if it stops moving, it falls over.
