The force of the IR proximity detection is that the IR flashes, detecting
the difference in incoming light will almost certainly only detect proximity
(and not overhead windows or lamps). You could propably get comparable
results with any kind of light as long as you keep it flashing. If you
connect a focused beam penlight to a motor-output so you always knew whether
it was on or not you could probably get even better accuracy than with the
IR.

| Just a thought, I haven't tried it but a small focused beam penlight might perform better. I like the IR better because it's not obvious to the uninformed just what is going on. I'm going to try moving the light sensor about to scan for objects. (...) (26 years ago, 14-Jan-99, to lugnet.robotics)
