1. Watching for white lines: Connected to Cricket 3 was one IR sensor, pointed at the floor. This IR sensor could distinguish between black and white surfaces, so Cricket 3 continually checked its value to determine whether or not the robot was crossing a white line (indicating that the robot was entering a room or within 12" of the candle).
2. Managing the control flow: At the highest level, Cricket 3 controlled the control flow as primary control was passed back and forth between Crickets 1 and 2.
