The 360 IR Beacon Transmits infrared signals that can be detected by the IRSeeker sensors so your robot can navigate to the IR Beacon position or estimate its position relative to the IR Beacon. The beacon has 6 IR emitters that transmit a coded signal and depending on the mode selected the signal will cover a full 360 degrees or 180 degrees. Mode settings allow you to select different signal frequencies and coverage. The IR Beacon transmits either a 600Hz or 1200 Hz signal allowing the IRSeeker sensor to distinguish between two different beacons. The beacon can be powered by either an internal 9V battery or by external 9V DC power source such as the 9V Battery Box.
