From TheArena, 3.2.5: "Each beacon emits at the same IR frequency, but sends pulse trains of different widths.... FIRST has supplied appropriate code that allows teams to program their robot's controller to make decisions based on a received signal and discriminate between the two Tee locations."

The beacons are not just a flashlight IR source, they send a modulated signal on a particular frequency. Robots using the code should be able to ignore most IR interference - though IMHO, testing with interference would be a good idea. I notice the humans were careful to stand far far away from the demonstration 'bot ; ) -Piece, Pteryx
