Re: New wheels / floor and encoders for position.
Why couldn't you use encoders with slipping wheels? The sensors will certainly tell you actually how fast the wheel is spinning. Maybe you can use that information with an expected PWM signal vs. speed curve for traction control?

For example, if you observe that the wheels suddenly start spinning from a low speed to a higher speed, assume that slippage is occurring and reduce the drive signal.

Cars are really starting to take advantage of traction control. Maybe FIRST robots can learn from them?
