Preface for younger CD'ers: computer mice used to work by rolling on a ball that would allow it to sense movement by its rotation.

I haven't heard of a team using an optical mouse, but I do vaguely remember a swerve drive team that used a mouse-ball to track it's position in autonomous way back in 2008. I didn't catch which team it was, unfortunately.
