Yes, it measures distance by the unraveling of a string around a spool. I was going to suggest that you could wrap the string around whatever you are counting the rotations of and use the circumference of the "wheel" to figure out the number of rotations, but it would only work if the rotating object only has to rotate a small number of times like a winch and it cannot rotate very fast. I have never seen this on a robot, but it could work I suppose. Could you reveal what this would be used for?
