I'm working on building a micromouse myself, and have found an excellent
source of small optical encoders for position sensing. Find an old, dead
mouse, and use the encoders from that. The mouse I have has two encoders,
mounted on a shaft with a small roller. I plan to mount the encoders on
the micromouse so that the roller rides on the top of one of the drive 
wheels. This should give me a very accurate measurement of the movement
that that wheel has made.

It shouldn't be too difficult to mount the encoders so that they can sense
the movement of a motor. If nothing else, mount them so that the roller
rides against one of the gears.
