I built a robot with the ArduRover firmware. It has a differential drive system with two brushless, sensorless drone motors and 3D printed gears. This video is an overview of the robot and what it can do. The robot was built entirely from parts I had lying around. The chassis is made of wood and painted to make it look a bit better. My intention was to use this robot as a base for adding sensors and other things and to experiment with some features in ArduPilot/ArduRover. Later I realized that I can't do much more because this flight controller only has 1 MB or flash. Maybe in the future I will change the flight controller, or make another rover.
