Draw a black line on a white piece of paper and the Hyper Line Tracer robot will follow the path of the line!
A light sensor which consists of an LED and phototransistors distinguishes the black colour from the white background and controls the electric motors to follow it.
The Hyper Line Tracer also comes with two flashing LED "eyes" that tell you which side of the light sensor is activated.
The robot comes as a kit with very clear instructions. A few basic tools are needed such as screwdrivers and cutters but all circuitry is pre-soldered meaning that no soldering is required.
