I know some of these were used for traction control. They would compare the rotation on their powered wheel encoders to the rotation in the unpowered wheel to see if they were actually moving as fast as they thought they were (if at all).
I know team 51 had some kind of location on their drivers station in 2010. I'm not sure why they used it, but it worked pretty well.
