Jonathon, Here are my "short" answers: 1) Reload your laptop fresh with Windows 98 to solve USB (and other) issues. 2) It is apparently possible to use the IrDA port to control 38~40KHz IR devices (RCX, Scout, TV, VCR, DVD). 3) The darkness issue (...) (23 years ago, 10-Jun-02, to lugnet.robotics)

I've been wondering if anybody has any ideas why they chose to go with IR as opposed to RF? The substantial limitations of IR make it highly impracticle for robotics. The only two reasons I can see would be cost or power limitations. I can't imagine (...) (23 years ago, 10-Jun-02, to lugnet.robotics)

I have thought about those methods as well, the only problem is when you don't work with the RCX's for just one robot. When you want to try a little bit with AI and interactions between different robots you can't have a master that requests, unless (...) (23 years ago, 9-Jun-02, to lugnet.robotics)

There's one way for solving the problem with multiple IR communications at the same time. The method used for old computer networks is called a "token" wich is passed from PC to PC giving each one a chance to "speak". This could also be used for (...) (23 years ago, 9-Jun-02, to lugnet.robotics)
