INFRARED BALL CHASING ROBOT

The Infrared Ball Chasing Robot is a small robot with two active wheels that follows a ball emitting modulated infrared light. The robot has several infrared sensors (“eyes„) that give the information needed for the robot to determine not only the presence but also the direction of the ball. The concept is based on the light-follower robot design. It relies on difference between the levels of light signals received by at least two sensors to determine the direction (angle) of the target in relation to the robot orientation and generate different wheel speeds accordingly, so that the robot moves towards the light source.
