Design and Implementation of Autonomous Wireless Vehicle

Autonomous vehicles gains increasing importance in various growing application areas. The navigation, guidance and control of an autonomous vehicle is a highly complex task. Making a vehicle intelligent and able to operate unmanned requires extensive theoretical as well as practical knowledge. This paper focuses on designing and implementation of GPS based autonomous guided vehicle navigation, guidance and control system. The designed system is able to reach the desired coordinates with minimum drift, high performance, and high stability. In particular, the inertial sensors were used to support the autopilot with the required navigation states required for estimating the error between the desired and actual trajectory. The idea of the algorithm that steering the vehicle till reaching the desired position is based on the modified PI-D classical controller that prevent differentiating the input signal in order not to obtain impulse chock to the actuators; the physical limitations and constraints that might be encountered while building an autonomous vehicle are taken into consideration. Experimental results for the designed PI-D algorithm are given to illustrate the effectiveness of the proposed technique. Keywords—Navigation; Control; Arduino;
