From the project
Generic repo for robotic projects with the former MiAM Eurobot team !
This repo contains information and software for robotic-related projects done with the MiAM Eurobot team.
Our robot architecture are based off an embedded linux on an ARM platform, Raspberry Pi or Beaglebone Black, programmed in C++. We also use Arduinos as slaves for low-level tasks such as motor control or sensor handling - using serial communication through USB.
