Gambit

A robotic chess board

Similar projects worth following

Gambit is a robotic chess board that utilizes magnetism for piece movement and movement detection. It employs an electromagnet on an H-Bot mechanism for piece movement and a reed switch matrix to accurately track piece positions. The core of Gambit is powered by an Arduino Nano ESP32, and it is primarily constructed using 3D printing.

The Arduino Nano ESP32 provides the potential for future Bluetooth and Wi-Fi connectivity, enabling connections to powerful chess engines and allowing for game recording capabilities through a companion app.

It looks like the pieces are on top of the plastic sheet and the movement mechanism is under the plastic sheet.  Correct?  Is there a way to sense which piece is on a square?  Or from the starting chess board setup, is it a requirement that Gambit moves all pieces?.

Interesting!  Please show pictures of how Gambit picks up pieces and puts them down.  A side view of the board would be great.

Thanks for interest in the project! It uses an electro magnet with each of the 3D printed pieces having a magnet placed inside, I can send a photo next time I am in the lab.
