Abstract

This project is about the implementation of GPS on a mobile robot in outdoor environment. The GPS consist of a 32 channel receiver and a GPS evaluation board, interfaced with a microcontroller 16F877A via signal converter. This project is categorized to three main parts which include electric circuit, mechanical design and microcontroller programmmg. The main objective of this project is enabling the automatic mobile robot to establish its own location on earth and use GPS information to navigate and move to a defined point. For further implementation, the mobile robot with better controllability might be able to construct. The concept of this project is to use GPS to gather information such as bearing, distance and location and compare with a defined point. The program can determine whether the mobile robot should move forward, tum or even move backward by differentiating the distance and direction. The program used to process the data is C language. C compiler will execute the HEX file which needed to be downloaded into the PIC chip. The mechanical part will use differential drive to perform movement of the mobile robot.
