Abstract

The use of robot vehicles for public transportation will reduce congestion levels and improve traffic flow. Obstacle avoidance is one of the most important aspects of robot vehicle. Without it, robot movement would be very restrictive and fragile. In this paper obstacle detection and avoidance robot vehicle which can detect obstacles in its path and maneuver around them without making any collision was designed. This robot vehicle can redirect it movement whenever an obstacle comes in its path so as to protect itself from any physical damages. The ultrasonic sensor was used to sense the object in front of the vehicle and send the signal to the micro controller unit. Depending on the input signal received, the micro-controller redirects the robot vehicle to move in an alternate direction by actuating the motors which are interfaced to it through a motor driver. The Arduino board was selected as the microcontroller platform and Arduino Software was used to carry out the programming. When the robot vehicle was placed in different environments, it was found that the robot vehicle was able to detect and avoid obstacle with an average accuracy of 83.62%.
