碩士 === 國立成功大學 === 工程科學系碩博士班 === 93 === 　The goal of this thesis is to develop a small outdoor automatic mobile vehicle, using PIC16F877 as its control chip. The objective is to make the mobile vehicle more adaptable, more functional, more expandable and more improvable. 　he Human-Machine interface system is achieved by BCB (Borland C++ Builder).The vehicle can be communicated with a notebook via wireless communication module. A user can send orders to control the vehicle and receive the data from the vehicle by the system. 　The ultrasonic ranging device on the vehicle is used to recognize cylindrical objects by the model of the focal length-diameter relation. The model is established by known diameters of cylinders and their focal lengths calculated from the curve obtained by the second degree polynomial. Moreover, we can recognize the landmark classes of simple discontinuous, simple continuous, complex discontinuous and complex continuous types. And we hope we can use the recognized landmarks for navigation strategy in the future.
