Easy. A light sensor.
Point the sensor at a disk that's shaded from white to black. I've used
that to detect the distance a robot is from a wall (wall following), using
just a black & a white dot (1x1) which are moved in front of the sensor. It
shows black, white, & gray.
It uses very little force, and doesn't lose counts (like a rotation sensor
could).
Is this for something we could see at BrickWorld? I hope so. :)

| Hi all, I am working on a "project" where I want to measure some reasonably small rotations, things on the order of +/- 10 degrees or less. Just to make it hard, the force acting on the thing being rotated is small, like, completely hypothetically, (...) (18 years ago, 20-Jan-07, to lugnet.robotics.nxt)
