Abstract:
Line follower robot is a robo-car that can follow a path. The path can be visible like a black line on the white surface (or vice-verse). It is designed to move automatically and follow the made plot line. The robot is using four light dependent resistance (LDR) sensors to identify the black line avoid the robot to steer away from its track .Robot is driven using dc servo motors to control the movement of the wheels. The atmega16 microcontroller will be used to perform PID algorithmsto control the speed of the servo motors steering the robot to travel along the line smoothly.
PID algorithms monitor and adjust the gain of robot used on the characteristic of the feedback, to improve robot performance .This concept can be applied for the an autonomous vehicle by applying the similar PID control method .PID control line following robot also can be modified into a guidance system for industrial robots that involving traveling in the building. Besidesthat, it also can apply in automated cars running on roads.
This project aims to implement the PID algorithm and control the movement of the robot by proper tuning of the control parameters and thus achieve better Performance.
