The project is designed to develop a robotic vehicle that follows a specific path. This project uses an Arduino development Board. A pair of photo sensors comprising IR transmitter and photo diode is interfaced to the Arduino to detect a specified path for its movement.
Line follower robot is a useful robot that is meant for use in ware houses, industries, and stores etc, wherein it follows a dedicated path. This proposed system of a line following robot fulfils the desired functionality and demonstrates the working of it. It uses a pair of photo sensors, comprising of one IR transmitter and a photo diode in each side. It guides the robot to follow a specified path by giving appropriate signal to the Arduino Board. Two DC motors are interfaced to the Arduino board through a motor-driver IC. Input signals are given to the arduino from the sensors, and then the controller takes the appropriate action according to the program written in it and drives motors as desired.
Furthermore, the project can be enhanced by adding more advanced sensors to it. This will add more features to the existing project. For example, we can use ultrasonic sensors for detecting any obstacles in front of the robot and to take appropriate action.
