Do this with more than one light sensor, and you can have much better spatial resolution (the ends of two fiber optic cables can (...) (18 years ago, 18-Dec-06, to lugnet.robotics.nxt)

I suspect I might be able to use it to follow lines drawn by a black marker. (...) No. Well, kind of. I used a (...) (18 years ago, 18-Dec-06, to lugnet.robotics.nxt)
