The concept of working of a line follower robot is based on the phenomenon of light. We know that white color reflects almost all lights that fall on it, whereas black color absorbs most of the lights. In case of a line follower robot, we use IR (Infrared) transmitters and receivers also called photodiodes to send and receive lights. IR transmits infrared lights. When infrared lights fall on white surface, they are reflected back and caught by photodiodes which generates some voltage changes. When IR lights fall on a black surface, lights are absorbed by the black surface and no lights are reflected back, thus photodiode does not receive any lights.

Solar cars (or solar vehicles) are a special type of electric vehicle that only get their power from the sun. They use solar cells on the surface of the car to produce electricity and the electricity makes a motor turn, and that turns the wheels. They can drive all day and not make any pollution.
