Set of electronic boards for Grabette/Gripette

This repository is part of the "Grabette" project. It gathers several small PCBs of Grabette/Gripette.

It is based on a battery-powered Raspberry PI 4 plus a HAT to which a serie of sensing elements is added. Camera, Stereo Camera, angle sensors, IMU (included on the HAT) and a button + a LED as user interface.

It also gathers data with the same Camera/Stereo Camera system and drive motors. The "under-HAT" electronic board is associated to a Raspberry PI zero 2W. It has a interface to the motors (now Feetech wiring). A Bulk-head board makes the mechanical interface with the arm that holds…
