Robot Chess but Each Piece is a Small Robot
2 min read
A maker built 3D-printed chess pieces called MiniBots that are tiny robots. Each MiniBot uses an ESP32-C3, two stepper motors, a magnetometer, and a 170 mAh battery. The open-source project localizes pieces by scanning board electromagnets. The prototype works but needs firmware fixes for the single-core MCU.
