Abstract

This paper presents a detailed description of a wall following an autonomous robot. It follows a wall on its both left and right. The robot used an Atmega 328P microcontroller as its brain. The wall follower receives input from Ultrasonic Distance sensors (HC-SR04). Mathematical computations are performed on this input, and a control signal is generated to control the robot's position. The pulse width modulation technique is used to control both motors with the help of a motor drive controller. The wall follower can be controlled from a remote location using WiFi technology.This document provides an overview of the Wall Following Robot and can be used as a quick reference for understanding.
