Of course, for the back wheels you could join the two shafts in a differential and the difference of the two would appear in the rotation of the casing (don't forget some reverse gearing to make the sum zero for two motors going in the same (...) (25 years ago, 21-Sep-00, to lugnet.robotics)

I was only using 2 sensors, and after 500 or so steps(about 15 ft), there was only a 1 count differenece. The main factor in determining what (...) (25 years ago, 20-Sep-00, to lugnet.robotics)
