Optical Line Recognition Sensors for Line Follower

Abstract

Paper deals with optical line recognition sensors, which are useful for line follower robots. Line follower is the category of robotic contests. The basic idea is to locomote with robot and follows the black line on white surface. Robot design is very frequently based on two wheeled differentially driven undercarriage with third supporting support wheel. The locomotion of the robot is controlled via using of microcontroller on the base of information from line recognition sensors. Selection of these sensors has a big role in robot design for this category of robot contest.
