How did you control your Robot? 1? 2? Wheel? How?

How did you control your robot?
What did you see that you liked?

670 used a negative feed back loop for its rear wheel diff system this year. This was controlled by a wheel and stick method. The stick to regulate power to the front wheel drive system, and the wheel to have semi-real time steering feedback.

Next year we are going to use the same control unit but the robot will be 6 wheel tank and the steering will be all software controlled. In the past we have used the "tank" method of driving but we found that it always drifted after a while. Team 254 solved that problem, they used the stick and wheel method only now when the wheel turns software sends exact opposite values to each side of the robot, this removes the problem of "human error" in driving.

Tell me how you did your steering or control unit.
