| Hi Mario, Mauro, (...) I tried to get away with a single rotation sensor on a differential drive (put it on one of the output), assuming that I one motor is not moving I could deduce total movement. Unfortunately the turning motor drifts slightly on (...) (24 years ago, 3-Aug-00, to lugnet.robotics)

| I explored the use of a single rotation sensor to make a robot drive straight here: (URL) can use a differential to take the difference of the two motors' output; if the motors are not moving at the same speed, you'll see some movement on the (...) (24 years ago, 3-Aug-00, to lugnet.robotics)
