[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.

Wanting to get back to playing with actual pieces, [Thomas Pototschnig] built a chess table that interfaces with the Internet. The table uses an custom setup to project the board on the frosted surface of the table. Chess moves from your internet opponent are displayed as arrows on the board so you can move the pieces. Your moves are detected by a webcam below the surface as this table actually functions as a multitouch display. From the description, it sounds like the projector was made from a 128×64 graphic LCD display. A 64×64 pixel area is used, with an LED below and a lens above. This works remarkably well. See for yourself after the break.
Want some other options for your chess setup? You can play against a robot arm, or if you’ve got 144 square feet of extra space you can build a really big board for the occasional game.

Over 100,000 Lego pieces, 4 people a year to create, and a 12 foot by 12 foot chess board make this the largest most awesome Lego hack we’ve ever seen. Take that Lego Printer.
For a mere $30,000 you too can have such a setup. Not a lot of information is out yet, but we do know all the pieces are remote controlled via a PC with LabVIEW and a total of 38 NXT controllers are used. Oh, and of course you can see it live at the 2010 Brickworld. Check out a video of a replayed game after the jump.

[Dennis] is using a robotic arm as a chess opponent. Rather than using an under-board movement system, a Lynxmotion AL5A robotic arm plucks each piece and moves it to the next space. He tells us that he’s using a Python script that he created to process the moves and decide what’s next. That must mean he’s using a webcam to capture the location of the pieces on the board. About half way through you can see the robot run into one of the pawns. We’d like to know if he has problems with picking up the pieces as the game progresses and they get further away from the center of each square. From what we can see, looks like a great job!
