Infrared Battling Systems
Infrared battling systems bring tank battles to life. Using an infrared emitter as a cannon and sensors located on the tank allow people to fire on and cause damage to their opponent. The damage is simulated using an Integrated circuit that counts the hits received and then adjusts power to the electric motors in the tank to slow it down and stop it. The amount of damage a tank can sustain is determined by its weight class.
