Why build a CNC mill when you can have a chess robot instead?

[Patrick McCabe] enjoys the challenge of playing chess against the computer but he wasn’t satisfied with the flat experience of on-screen gaming. No problem, he just built his own gantry-style chess robot that he can play against. Don’t be confused, he still doesn’t have to touch the pieces, but instead uses the dedicated control board seen on the left of the image above. The robotic arm that is mounted on a gantry takes care of moves for both players.

It’s a pretty normal CNC build, using four stepper motors to slide the moving bits along precision rod. An Arduino Mega drives the system, with a PC doing the heavy lifting using a program called My Robot Lab.

We certainly like it that [Patrick] spent a little bit of time making the cabinet and visible parts look nice. Chess is a civilized game and unfinished parts would be out-of-place. We didn’t see it in his writeup, but the one feature we’re really hoping he has implemented is the ability to have the robot automatically reset the board at the beginning of a game.

As you might have guess, you’ll find embedded video after the break.
