Is it permissable to have an IR beacon

[nathanww]

A thing to keep in mind is that this person is sitting behind a plexiglass shield, at an unpredictable angle relative to the robot, possibly with obstructions(other robots) in the line of sight. This means that recognition based on a shape or pattern like a barcode probably won't work, which leaves you with just using color as a beacon. Even with just a bright orange hat or something, the robot has to be able to pick up that signal and distinguish it from the background, which can be tricky in and of itself.

And here is what the GDC has to say about this sort of thing: http://forums.usfirst.org/showthread...3229#post23229

They haven't said anything about other colors.
