This video is of a pretty strange contraption which moves foward using the two legs of a wishbone. It looks like there is a battery on the back of the contraption which is connected to a small motor. The motor turns a large wheel which has a belt that connects to a smaller wheel. The smaller wheel has a level much moves fowards and backwards as it turns causing the wishbone at the front to walk forward on it's two "legs". The back of the contraption is on two small wheels. I don't know if this is some kind of robot locomotion test machine or what.

Anyway check out the strange contraption of the walking wishbone for yourself.
