| | | Tim, Instead of using the differential for angle sensors, why not use it to allow a single motor to drive both wheels? Then a single angle sensor coupled with a motor could drive the steering mechanism. This setup would be very similar to a radio (...) (26 years ago, 13-Nov-98, to lugnet.robotics)

| | | | | (...) At one point, in the distant past, I saw plans for a gear box that used either 2 or 3 differentials, I do not remember which. 2 motors were used, 1 to drive both axles, one for steering. axle1 == motor1 + motor2 axle2 == motor1 - motor2 With (...)
