This is an interesting idea, but I think you will have a problem common to
most dead-reckoning navigation solutions and that is that wheel slip, mouse
ball slip, and the differential slip between the two (i.e., if the robot
wheel slips, the mouse may not, and vice versa). It may not be a better
solution, but why not try some type of optical or magnetic encoder?

| (...) Of course! But for some applicvations, that isn't a big problem - and if it works it is cheaper and simpler than other methods at the same precision (I think) As a matter of fact, I am working on a way to use a pattern printed on the floor and (...)
