From the project
Super cheap super tiny bots for....playing chess...
A swarm robotics platform built around autonomous chess. The system runs 34 small differential-drive robots across an 8x8 board, each independently localized and coordinated by a central Python application running on a Raspberry Pi.
The design is general-purpose — chess is the primary use case, but the platform works for any scenario requiring coordinated movement of many small autonomous robots in a bounded space.
