I believe it was Mario that described a way to use the FO device as a
rotation detection unit all by itself. Apparently as a side-effect of the
rotation the FO device can toggle the pulse counter as well. It can't detect
direction like the true rotational sensor, but it apparently can detect
rotation - counting clicks may then allow you to fix end-point stops.
Does anyone else verify what I just said or is my memory shot?

| Dennis, You are absolute correct. No brain cell problems on this issue. I can't remember the part about Mario, but it makes sense.. Jin Sato has used these on the front legs of his Mibo dog to determine motion. He knows the direction that he is (...) (25 years ago, 21-Dec-99, to lugnet.robotics)

| The fiber-optic device and a light sensor can be rigged to detect at least two distinct rotation positions of an axle. The fiber optic device is lit through an electrical connection, and an axle turns an internal light source, sequentially lighting (...) (25 years ago, 21-Dec-99, to lugnet.robotics)
