I am currently working on this very project. I have decided to use 2 RCX's
as I want to keep the project strictly Mindstorms. I realize that IR won't
allow the car to go very far from the controller, but I'll live with that.
Unfortunately I only have one RCX at this time. I have completed the
prototype of the controller first as I thought that would be easiest. The
controller uses two rotation sensors (forward/reverse & left/right) and a
touch sensor (for the turbo button). I should have a DAT file available
this week. The source code written in NQC uses the SendMessage() command to
tell the car what to do. Again, it's hard to test the program with only one
RCX :)

There is a signal pattern (which can be either FM or AM depending on the waveband of the radio) that represents a train of pulses that (...) (24 years ago, 29-Aug-00, to lugnet.robotics)
