Ditto on having it ready but not counting on it. I think it's going to be a bunch of jumbled IR by the time it reaches the robots with so many remotes/bright stage lights pointed all over the place. Ours stops working if we just shine a flashlight somewhere near it, let along one of those tens of spotlights FRC puts on the field. Also, if two remotes are pointed somewhere near the reciever, this also makes it stop working.
Putting a tube on it to confine the beam again renders it almost useless, since you have to have your robot essentially pointing right at you for it to work, and the point of the remote anyhow is to (perhaps) guide the robot back to straight from a misalignment... so you might not get any signal in the first place.
*sigh* but that's ok... that adaptive cruise control's starting to work miiiighty good....
