The problem with IR is that it tends to get everywhere, reflecting off of surfaces etc, so it's hard to triangulate. May I suggest a related but different approach. Make your beacons out of hybrid IR/sonar transmitters. The beacons will periodically (...) (22 years ago, 1-May-02, to lugnet.robotics.handyboard)
