There's no reason why the four commands couldn't be used in combination:
cmd1, cmd2, pause, cmd1, cmd2 ...

giving 16 possible combinations, or 64 etc.

Might be game pieces telling the robot what state they are in.

"Busy", "Ready", "You Scored", "Go Away", "Red Team goal", "Blue Team goal ", "Penalty for using", "Extra Points Now!".... endless possibilities.

I wonder how many games we could come up with that are not the one for FRC 2008.

Possibilities increase if the robots can also send commands.
Remember - it's all idle speculation - we just don't have enough info.

As for the interference - mount the receiver in a box and make it look down a tube, it'll become very sensitive to direction and less able to be interfered by another transmitter.

Problem: I get which cables do what, but we only have one cable for each output, and dig ins are pwms, aka 3 cables. How do you wire it to connect?

thanks for any help

Well I have a thought for the moment and I wonder the significance or potential impact to the actual usability of this device.

Most event venues that I have attended use tungsten/halogen lighting. With all that IR being thrown out on to the field from the lighting it will make using IR as a requirement for this year game quite the challenge to over come.

What is a halogen bulb?
Halogen is a type of incandescent lamp. It has a tungsten filament just like a regular incandescent that you may use in your home, however the bulb is filled with halogen gas. An incandescent lamp produces light by heating a tungsten filament.

How much heat or infrared radiation is emitted by halogen light bulbs?
Because incandescent and halogen bulbs create light through heat, about 90% of the energy they emit is in the form of heat also called infrared radiation.

Any other intriguing thoughts on this aspect?

IR remotes work in buildings and arenas with Halogen lighting. One aspect is the sensitivity angle. Think of what happens when you are too far to the left or right of your TV when you go to change channels... nothing happens until you get in front of it. Other thing to remember is the signal is modulated on a 38kHz(?) carrier. Lights won't put that frequency out. So, the receiver is looking forward and not up and is modulated so the lighting shouldn't be an issue.

For the cmd0,1,2,3 signal wires turn the pwm connector sideways and push it onto three side-by-side signal pins leaving the ground and power pins unconnected.
One signal pin will be the odd man out of a standard three wire cable, so you can either use two cables or you can spring for your own female connectors and a 4-pin connector housing.
