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 (...) (23 years ago, 1-May-02, to lugnet.robotics.handyboard)

I am beginning to design a handyboard robot that, for starters, can navigate around a room. The idea is that it will travel to objects whose coordinates within the room are predetermined and interact with them. I plan to do this by triangulating the (...)

A few months ago I attempted to discover how VC was accessing the Lego cam. My theory is that VC only cares what driver is being used either due to contract with Lego or because VC may rely heavily on the Logitech QuickCam SDK. Here's what I've (...) (23 years ago, 29-Apr-02, to lugnet.robotics)
