Pinky (chaperoned by graduate student Dan Paluska) is the prototype of the next walking robot from the MIT Leg Lab in Cambridge, MA. Established in 1980 by Marc Raibert, the Leg Lab was home to the first robots that mimicked human walking?swinging like an inverted pendulum from step to step. Famously, Raibert even built a robot that could flip itself in an aerial somersault and land on its feet. From the book Robo sapiens: Evolution of a New Species, page 182.
