碩士 === 國立暨南國際大學 === 電機工程學系 === 98 === In this thesis, we implement a wireless navigation self-propelled car which is guided by the wireless packets generated by reference nodes in a ZigBee networks. The car, equipped with a rotational directional antenna, can automatically trace the direction of the current reference node and move forward to it. Users can setup an arbitrarily route consisting of some selected reference nodes in the ZigBee networks, and the self-propelled car can move hop by hop to the destination. During development, we overcome the non-matching issue of driving motors and implement a compensation program such that the car can move straight or correctly change its direction. We also design a flexible communication protocol between the two processors in our system. The wireless navigation system is proved effective by prototyping and can be easily applied to robots.
