How are you implementing traction control?

[Jared Russell]

Limiting the commanded acceleration of your drive wheels can prevent wheel slippage - but ONLY in the absence of unaccounted external forces. If you are running into the arena walls and other robots, this assumption is no longer valid.

In other words, this type of traction control would not help in a pushing match.

This is how we're doing it...

Your wheel speed is given by a magnetic rotation sensor (what controls your volume in your car). This is compared to to integrated accelerator value, over 20ms. Find the difference, correct the motor speed, use some ifs to determine if your driver is accelerating your decelerating. Then out put the correct speed of the robot to the wheel, plus a tiny fraction of acceleration energy, or none if you want to hold constant speed...
