LINE FOLLOWING ROBOT USING ARDUINO

Abstract

This project details the design, development, and evaluation of an autonomous line following robot using an Arduino Uno micro- controller. The robot navigates a predefined path marked by a line, employing infrared (IR) sensors for detection and a Proportional_x0002_Integral Derivative (PID) control algorithm for motor control. The hardware setup includes an Arduino Uno, IR sensors, DC motors, and an L298N motor driver mounted on a compact chassis. The software, developed using the Arduino IDE, processes sensor data to compute the error between the desired path and the robot's actual position, which is minimized using a PID control algorithm. Extensive experiments on various track configurations demonstrated the robot's high precision and stability in following lines. The PID controller's dynamic motor speed adjustments allowed the robot to efficiently navigate complex paths, outperforming traditional threshold-based methods. This research highlights the robot's potential applications in automated guided vehicles (AGVs), industrial automation, and educational tools.
