This Circuit of Line Follower ROBOT has been getting from VingPeaw Competition Award winner in 2543, the robot built with mikrokontroler AT89C2051, L293D, and four IR sensors. Simple circuit and platform, quick tracking and easy-understand program using C language.
The Line Follower ROBOT designed which use two motors control rear wheels and the single front wheel is free. It has 4-infrared sensors on the bottom for detect black tracking tape, when the sensors detected black color, output of comparator, LM324 is low logic and the other the output is high.
