DIY Chess Playing Robot Arm

After looking around and doing a bit of research, I found an article about an interesting DIY robotic arm that could actually play chess.  The system, developed by Norris Labs, uses a Lynxmotion AL5D robotic arm to grab pieces, but does not rely on the arm as a primary source of movement.  The arm is mounted to a cart, which positions the arm.  In addition to this, the chessboard can rotate up to 180°, so the arm never has to reach more than four squares into the chessboard.  The robot itself doesn’t understand chess, but players can remotely send their moves via a service such as Twitter, and view the game’s progress through a webcam.  A player can also play against automated chess-playing software.
