| Summary: | 碩士 === 逢甲大學 === 航空工程所 === 93 === In this thesis, an obstacle avoiding and navigation for an automatic mobile vehicle, which includes the main control and vehicle segments, is developed and evaluated. For the main control PC part, the interface of application program is designed and programmed by using the Visual Basic software; whereas the vehicle part contains ultrasonic sensors, GPS receiver boards, and the microcontroller chip (AT89C51) which serves as the core of control systems.
The whole system, which utilizes the multi-communication/process technique, and the integrations of sensors, actuators, and controllers, works perfectly. It conveys GPS information to PC through the onboard RS-232 port and the revised route commands will be sent by using the wireless system. The results of experiment also indicate that the practical GPS application program which receives and displays the procedure/track of the vehicle is well-developed, and the success of combining different controllers, and the integration of different structures of the hardware and the software.
