Abstract-Mobile platforms, by means of Bluetooth technology, the use of autonomous systems in the world to perform important and delicate task is rapid growing. However, its application in various fields cannot be over emphasized. This paper presents an obstacle detection and avoidance system for an fixed 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 route by sending signals to an interfaced microcontroller. The micro-controller redirects the robot to move in an alternate direction by actuating the motors in order to escape the detected obstacle. The performance evaluation of the system indicates an accuracy of 85% and 0.15 chance 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 clarify the output and makes the robot to pause.
