We’ve seen a few chess robots in the past, but nothing quite this complicated. In this build, the chess board will actually rotate to move within reach of the robot arm. The arm itself moves along an axis to move each piece. You can play against the robot itself, or you can play against a friend on the internet, and the robot will act out your moves.
In a more interesting scenario the players can be located remotely using a social networking service such as Twitter to send and receive moves and then observing the results on a Webcam. For automated play one of the human players can be replaced by chess playing software commonly referred to as a ‘chess engine’.”[LINK]
