Apparently as a side-effect of the rotation the FO device can toggle the pulse counter as well. It can't detect direction like (...) (25 years ago, 21-Dec-99, to lugnet.robotics)

| | | | 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)

| | | | It was not me to discover it, but it's definitely doable. You can use the fiber-optic device as a rotation sensor and it works pretty well. As Dennis and Phil said, the only point is that you cannot detect the direction, but in many cases you (...) (25 years ago, 22-Dec-99, to lugnet.robotics)

This lets you see the results on both the RCX LCD and the fiber-optic strands. Turn the axle until (...) (25 years ago, 22-Dec-99, to lugnet.robotics)
