Obstacle avoiding robotic vehicle with arduino and ultrasonic sensor

Abstract

Obstacle detection and avoidance is one of the most challenging problems in the design of mobile robots. Without it, a robot movement would be very limited and flimsy. The obstacle detection and avoidance is like a built in intelligence that grants the robot the senses, which helps it to navigate in any unfamiliar environment without causing any physical damage to itself. In this project, an attempt is made to design an Obstacle Avoiding Robotic vehicle, which can sense the obstacles in its path, can evade them and can resume its running. This Robotic vehicle is microcontroller based and the obstacle detection and avoidance is done by using distance sensors or proximity sensors, which detects the nearest obstacle distance and sends commands to micro controller to maneuver the robot   around the obstacle without making any collisions. Arduino Uno board is selected as the microcontroller platform and Arduino software is used for programming purposes. The robot is designed in such a way that it can cover the maximum area of provided space. The hardware used in this project is widely available and inexpensive.
