Last year at Raspi, i was trying to make the ooyoo numcum rover i was controlling drive automatically with Drone software, but it didn't work out, so i have been learning at the Yousei-Jyuku since April.
The Falcon-mini controller was replaced with a RadioLink because I couldn't install Rover 4.0 and it was unstable even with PWM motor control.
The motor driver was also changed from the low-cost L298 to the proven RoboCrew driver for the ArudiPilot. The RoboCrew wiring also included encoder wiring to allow for standalone motor testing.
