Sensor-Based Obstacle Avoidance for Autonomous Mobile Robots: Experimental Study

Abstract

One of the highly essential issues in robotics is to let the mobile robot reach a predetermined location in the presence of obstacles. Many algorithms had been implemented for obstacle avoidance in an unknown environment. In this research, an algorithm has been presented for the mobile robot to perform this task. This algorithm is based on the use of sensors. The robot was programmed to use various sensors such as ultrasound and infrared sensors. The proposed algorithm was implemented in many environments, which contains several obstacles. The experiments show that the mobile robot has successfully avoided the obstacles located on its path to the predetermined target.
