Question on Motor Bias
With a finished robot, we're not so finished.

We seem to have a slight problem at extremely low speeds, with our drive train. We're using 4 CIMs, Banebots planetary transmissions, and KOP AndyMark wheels.

At low speeds, when moving the joystick forward, one wheel moves faster than the other. However, when moving the joystick backwards, the other wheels moves faster than the original one.

This implies that at higher speeds, the motors move in sync.

Could this be a possibility of motor bias? Or is it a trimming issue (which by the way, may take forever due to the ultra-sensitive touch) ?

Thanks for the help in advance!

Ah, and yes, our wheels were off the ground at the time.
