Line_follower_robot
- robot is designed to be able to follow a black line on the ground without getting off the line too much.
- The robot has 3 sensors installed underneath the front part of the body, and two DC motors drive wheels moving forward
- A circuit inside takes an input signal from 3 sensors and controls the speed of wheels’ rotation. using the microcontroller as the brain of the robot.Microcontroller will active the motor if right and left sensor high active and the middle sensor is low active.
- The control is done in such a way that when a sensor senses a black line, the motor slows down or even stops
- Then the difference of rotation speed makes it possible to make turns. For instance, if the sensor somehow senses a black line, the wheel on that side slows down and the robot will make a right turn.
