What are you building?

Basically, a line follower robot is a self-operating robot that detects and follows a line drawn on the floor. The path to be taken is indicated by a white line on a black surface. The control system used must sense the line and maneuver the robot to stay on course while constantly correcting the wrong moves using feedback mechanism, thus forming a simple yet effective closed-loop system.

Benefits:

It consists of mainly four parts: two sensors, two comparators, one decision-making device and two motor drivers. The robot is built using microcontroller AT89C51 (used as the decision-making device), motor driver L293D, operational amplifier LM324 (comparator), phototransistor (sensor) and a few discrete components.

Parts list:

AT89C51 microcontroller, L293D motor driver & 2-DC motors, LM324 Op-Amp, Photo transistors, Robot chassis etc.
