Design and construction of low cost sensor and GPS based autonomous unmanned ground vehicle

Abstract

In recent years, unmanned vehicles have been quite popular for the researchers and those vehicles are still being developed by the researchers and engineers. Unmanned vehicle must do all operations without operator and must has all capabilities as controlled by the operator. In this study, tracking of waypoint by autonomous unmanned ground vehicle (UGV) has been studied. For this purpose, designed and constructed unmanned ground vehicle location is obtained by using a low cost GPS and a compass. A microcontroller is utilized as a control/decision maker. An RC vehicle chassis and motors were used as the platform. Thanks to the work program loaded on microcontroller, UGV travels the destination points by directing actuator motors. Besides, Kalman filter algorithm and a guidance system was applied to UGV. The applicability and feasibility of the integrated system has been tested and the results are given at the end of the study.
