Abstract:

This paper describes an autonomous rover which is a self-piloted vehicle that does not require an operator to navigate and accomplish its tasks. Autonomous vehicles are a recently developed subset of robotics and can come in three general forms; air, ground and submarine. My GPS controlled autonomous rover is presented which employs a GPS Receiver Module to capture the GPS signal and determine the current location of the vehicle. The system is controlled using a microcontroller, a magnetometer and dc motors. The magnetometer determines the vehicle direction by continuously providing measurement of heading. The microcontroller drives the DC motors to move the vehicle to a manually entered destination coordinates. Obstacle detection and avoidance are achieved by incorporating the ultrasonic sensor to measure the distance between the vehicle and the obstacle, and avoidance is implemented by the microcontroller. The performance of the vehicle is enhanced with a capability to detect and avoid unexpected obstructions placed in its path. The designed GPS autonomous rover is able to navigate itself independently from one location to a second, user-prescribed location, using GPS-location data. The vehicle measures the bearing angle, and changes its heading towards the destination and repeats the process as it moves to the destination. GPS offers the benefit of retrieving location information that has no bearing upon previous results. This prevents calculation errors from accumulating throughout the path. For this reason, low cost, and ease of use.
