: Has anyone noticed that the drill motors have a different angular velocity when in forward than in reverse? If so, how have teams overcome this problem if they use the motors for the drive system?

We have always used a tank drive system with one joystick for each side. I don't think the drivers have even noticed that they need to slightly compensate. Even if they do, it should become a habit and never be a problem.

Using a mechanical system to compensate may very well be a worse idea than leaving it alone. Even if it means that you slightly increase the efficiency in one direction, you very well may lose that advantage when you consider the complexity of the mechanical system, as well as the extra friction that it introduces.

Using software to compensate is almost as bad. You lose some small range of motion that may come in very usefull later on in competition.
