碩士 === 國立雲林科技大學 === 電機工程系碩士班 === 97 === The purpose of this thesis is to design a tracked robot that contains navigation and avoiding obstacle. The controller of the mobile robot is a HOLTEK mircochip. The structure of the track robot contains the main body of the robot, motor driving device,a GPS system and a digital compass. Users control the mobile robot using nRF905 module which is a wireless RF interface. Using the Pololu motor driver can control the DC servomotors of the mobile robot. We use the pulse width modulation (PWM) technolngy in the speed control of the track robot. In the postion aspect, the Global Positioning System (GPS) and a digital compass are used to calculate the longitude, the latitude, the direction and the position of the tracked robot. To avoid obstacles, a photo sensor is used .The superused interface is written by the Visual Basic 2005. Users can give the commands on the superused computer transmits the signal to the microcontroller of the track robot using nRF905 module is wireless RF interface. The microcontroller will control the track robot and it will transmits the track robot’s position to the control center and reach the goal of outdoor self-localiztion.
