Robotic chess boards are nothing new. They have been around for decades but are getting smarter with Stockfish integration these days. The Milton Bradley Grandmaster is an electronic chess board that uses a robotic arm underneath to move the magnetic pieces. It was built in the early 1980s and has 12 levels of play.
While the Electronic Grandmaster doesn’t have the strongest engine, it has hint, replay, auto setup, and auto play functions. This chess robot was marketed as MB Phantom in England, MB Grandmaster in the US and Milton in Germany. The above video shows it in action.
