Watch a cat madly chase the red dot emitted by a laser pen and you pretty much have the principal behind the infrared tracker remote control car. This is a clever piece of technology which simplifies the process of driving an r/c car. Point to where you want the car to travel and it will simply follow the red dot to the destination. The one limitation of the car is that it can only track the red spot up to a distance of five feet, so if you are looking to move the car great distances, slow and steady is the course for the day.
