Out of curiosity, has anyone ever attempted to modify an optical mouse to do movement tracking for an FRC robot?

Something like this: http://hackaday.com/2013/04/03/addin...omous-vehicle/

I would think that it should be very inexpensive parts wise and should track well on carpet.

Though it would get a bit more complex if you wanted the device to not be in physical contact with the field.
