The primary facts of iGoBot

Design the base and the mechanics

Shortening of the Ikea "Lack" table legs:

The recognition on the Raspberry Pi in Python:

A first test for the "stones on board" recognition and translation into coordinates:

The stone dispenser

The electronics

The first arrangement of the electronic components

A first, very wild test of the wiring
