-players transmitting at the same time interfere with each other
-2 teams with the same signal for different things can mess with each other

If the sensor is on the field:
Robot has transmitter
-need to be fairly accurate with the transmitter
-2 robots transmitting at the same time = nothing happens (interfere)
player has transmitter
-isn't there an easier way than IR, like just 4 buttons?

If the sensor is at the player station:
field has transmitter
-why use IR for this?
robot has transmitter
-robot can transmit data through the radio, why use IR?

If there is an end game autonomous, is it possible that both the transmitter and receiver are on the robot? The robot then would change programs during autonomous as they encounter objects on the field that block their path toward the cold cathode.

Forgive me for not having read 40 pages of comments yet, but I just got the IR receiver today (drat snow days!)

Could it be that alliance robots will have the ability do communicate with each other?

While it is possible, I doubt thats what they will be used for. Each reciever can only interpret 4 IR signals and they are easily jammed. This makes for very limited and dodgy communications.

If they are on the robot (my belief) then most likely there will be 4 phases to the game and the field will emit the IR signals defining what phase it is in.

So here's a new thought...
FIRST sends us a sensor with a hunk of pretty rainbow ribbon cable. Does this mean we can go back to sane wiring practices like using ribbon cable to wire our sensors, rather than being restricted to using big hunky 24awg or larger stuff? After all, they've been giving us 30awg PWM splitters all these years.
