The objective of the research work to focus on a path planning aims to plan the route of an Unmanned Vehicle (UV) using Global Positioning System (GPS), and the most suitable path is selected avoiding the obstacles along the desired path. The coordinates of the starting point and destination are fed through programming. In addition, an obstacle avoidance algorithm is used and waypoints are given using the AVR Programming. Waypoint Navigation System for the Unmanned Ground Vehicle is use with GPS avoiding the obstacles in its path. The Waypoint Navigation System is the planning of the path of an object so that the path goes through some specified coordinates or benchmarks to the final destination thus avoiding any obstacles. The technology used to accomplish the aim includes Global Positioning System (GPS), Ultrasonic Sonic sensors and Micro-controller for programming. GPS will be the guiding medium from source to destination and two Ultrasonic Sensors will be used. These types of vehicles are used for many purposes and have been used by United States of America for Military and Defense purposes. In advanced cases, an Unmanned Aerial Vehicle may also be developed using these algorithms. [ABSTRACT FROM AUTHOR]
