The short answer is yes. The motors are not equal. You'll see designs using just one motor for the drive train for this reason. I'm in the process of toying with two rotation/angle sensors, one on each motor to see if I can programmatically synch (...) (25 years ago, 29-Dec-99, to lugnet.robotics)

In regards to the two motors included in the standard Mindstorms set, is it possible for one to turn faster than the other? I think I may be experiencing that... Any answers would be helpful. Thanks in advance. Bryan (25 years ago, 29-Dec-99, to lugnet.robotics)

They detect magnetic fields, so if you put a small magnet at the head of the passing train in a place such that (...) (25 years ago, 29-Dec-99, to lugnet.robotics)
