A Traction Control System looks at the all of the wheel speeds and determines which are slipping, then slows only those wheels.
My team is definitely trying to do this [4WD, all independently driven] but we can't figure out one thing:
How do you determine if a wheel is slipping when all four wheels are powered?
Any answer would be appreciated.

An accelerometer perhaps? It's not bullet proof, but I'd imagine it could work pretty well. You can figure the theoretical limit of your acceleration. If you're slipping, you aren't accelerating that fast. So slow down until a decrease in wheel rpm produces a slight decrease in acceleration.
