The big problem with IR as a whole is anyone in the stands with a 38khz remote can mess with any robots that are facing toward the stands. I do agree that if emitters are on the field they will be fixed, but that limits it to probably 4 sensors unless there are walls on the field to stop stray IR.

well how many inputs can you have on the board??? 4!
and as for interference, you don't get a good signal to the recieves after about 20 feet max. and really how far are you going to be from the goal to want to know what it is saying, chances are you'll have to be up close
Material bounce may be a problem though.... lol...
And as long as the IR doesn't control the robot but just gives it signals, and FIRST takes into account outside interference, I'm still seeing fixed field emitters as the way to go!
