| This is not what we did with our models. In the method we, and others have used, you apply the motor power to the carriers of the differentials. There are two possible places to apply the drive force to each carrier (24 teeth or 16 teeth). You do (...) (25 years ago, 1-Feb-99, to lugnet.robotics)

The explanation of the adder/subtractor was to allow one to power each wheel while the differential compensated for the different motor tolerances, allowing the bot to travel in a straight line.
