Obstacle Avoidance Robotic Vehicle

Abstract

In today’s world the use of the robots in industries and in enormous technological applications has seen to be highly impactful. The use of the autonomous systems and their good performance in dangerous tasks is greatly helpful for human beings. Obstacle detection is considered as the primary requirement for an autonomous robot. The obstacle avoidance is an autonomous robot which is used for detecting the presence of an object or an obstacle and avoiding the collision that makes both the robot and the environment safe. To develop an obstacle avoidance robot, it requires desired sensors and motors according to the task. This paper is about  developing a robot system which detects the obstacle and avoids the collision. This system consists of an ultrasonic sensor, Arduino Uno microcontroller, and 4 DC motors that make the robot move in an unknown environment. The ultrasonic sensor which is mounted in front of the robot is used  to sense the obstacle's presence and send the detected  information to the microcontroller. Based on the information received by the controller, the robot will move forward, backward, right and left. An Arduino microcontroller is mainly used to control the vehicle and to achieve the desired detection and avoidance operation.
