Professor Martin Mason describes his robot's hardware control system, which uses an RC controller chip and PWM receiver to drive two motors in opposite directions for turning. A long shaft connects the differential drive mechanism.

And there's also an RC controller chip on here which will let me plug an RC receiver, a standard pulse width modulated RC gearbox into here and then I can control the motors from that. So there's differential drive by driving one motor forward, the other one in reverse, I'll turn in one direction, reverse goes the other way. And then if they're on a long enough shaft,
