[BHOP]

my conclusion is that the field will communicate to the robot, a solid, strong single signal that will probably change based on the state of the game(think offense, defense,ffa). IR is too shady try to communicate back and forth, but if you have enough power and transmitters i think the field could cut through anything, and render all auto focusing stuff useless. This could even be another lair of safety! I wonder why IR.......
