Re: **FIRST EMAIL**/FRC Game Hint #2
One thing to keep in mind about PCM (pulse code modulated) IR transmitters (remotes), they will interfere with each other. If two or more PCM encoded IR signals are broadcast at the same time, they will interfere with each other. The decoder will not be able to use either signal.

I doubt FIRST would allow teams to use IR to contol the Robot becasue it would be too easy to jam each other. IR is invisible and would be impossible to prevent.

Whatever FIRST plans to do with them you can bet the IR beams will be separated. Probably beaming out from the center of the playfield in quadrature.

Another possiblilty, the signals (1 of 4) will be sent out at different times. Channel 1 for the first 15 second, channel 2 for the next, ... Maybe the Robots will have to follow and respond to these IR becons.
