An Autonomous Obstacle Avoidance Robot Using Ultrasonic Sensor

The use of robot and its enormous technological applications in today‟s era of industrial and intelligent systems has been seen to be highly impactful. The ability of these robots to move freely with minimal control is posing a real challenge. In this paper, the development of an autonomous obstacle avoidance robot using ultrasonic sensors is presented. In the design, the ultrasonic sensor serves as the eye of the robot to aid its autonomous movement. The robot is a wheeled type which can either be control using a dedicated control application (Android App) or autonomously. The control application was an added feature in case there is need to manually control the robot. The accuracy of the robot obstacle avoidance is highly encouraging scoring 87.5%, although, there are other challenges which are noted for further study.
