A team led by Steve Hassenplug built programmable chess piece robots using LEGO's Mindstorms system. They used $30,000 worth of LEGO pieces to construct this chessboard, which appears to be about fifteen feet across. The robots are programmed to get out of each other's way and leave the board when they've been captured. The video above shows them as flat objects. But Hassenplug also built animatronic pieces, and you can see them at the link.
