DEVELOPMENT OF AN ARDUINO-BASED OBSTACLE AVOIDANCE ROBOTIC SYSTEM FOR AN UNMANNED VEHICLE
The use of autonomous systems in the world to perform relevant and delicate task is fast growing. However, its
application in various fields cannot be over emphasized. This paper presents an obstacle detection and avoidance system
for an unmanned Lawnmower. The system consists of two (Infrared and Ultrasonic) sensors, an Arduino microcontroller
and a gear DC motor. The ultrasonic and infrared sensors are implemented to detect obstacles on the robot’s path by
sending signals to an interfaced microcontroller. The micro-controller redirects the robot to move in an alternate direction
by actuating the motorsin order to avoid the detected obstacle. The performance evaluation of the system indicates an
accuracy of 85% and 0.15 probability of failure respectively. In conclusion, an obstacle detection circuit was successfully
implemented using infrared and ultrasonic sensors modules which were placed at the front of the robot to throw both light
and sound waves at any obstacle and when a reflection is received, a low output is sent to the Arduino microcontroller
which interprets the output and makes the robot to stop
