This question seems to come up a lot here so I thought I'd post to the list rather than reply individually. Here's what I'm doing for IR collision avoidance. First, the hardware: I'm using 3 Radio Shack IR LED's in parallel and 3 Radio Shack IR (...) (28 years ago, 24-Feb-97, to lugnet.robotics.handyboard)

(...) Good question! We had a lot of noise problems and learning curve stumbles along the way. Our first bad news was that we had a range of a few inches. We finally beat that one fooling with frequencies, caps, etc. and then found out our range was (...) (28 years ago, 27-Feb-97, to lugnet.robotics.handyboard)
