The robot uses infrared (IR) sensors to detect the line on the surface. The feedback from these sensors is processed by the PID control algorithm, which adjusts the motor speeds in real-time to keep the robot aligned with the line.

Proportional (P): Corrects the position based on immediate errors.

Integral (I): Eliminates residual offsets by accounting for past errors.

Derivative (D): Predicts future errors to prevent overshooting.

This project demonstrates the implementation of a high-speed of 0.8m/s and had accuracy of 98.27%, PID-controlled line-following robot, ideal for competitive robotics or learning control systems. The combination of real-time feedback and precise motor control results in efficient navigation along a path, adapting to obstacles and deviations.Single Layer-Printed Circuit Board (PCB) micromouse is designed. It is

fabricated and assembled at an in-house facility. The dimension of Fastest Line Follower is about  174 mm (L) x 128.27 mm (W) x 50 mm (H).
