本研究目的為製作一移動平台，以做為服務型機器人的移動載具。本研究的創新處在於將傳統的指南車用來做為此平台的方位感測器。和機器人上常用的電子羅盤比較，使用指南車的優點為其不像羅盤易受週遭導磁性物品或馬達的電磁場所干擾。經由實驗測試，指南車模組可有效偵測平台在行進間之角度變化。我們並可利用此資訊使平台行沿一直線運動，或控制平台轉向的角度。

The objective of this research was to develop a mobile platform that can be employed as a vehicle of a service robot. To help the platform detect the change of its orientation, an innovative idea of using the traditional south-pointing chariot on the platform was realized. Compared to the electronic compasses commonly used on robot platforms, this south-pointing chariot has the advantage of not being affected by the change of the magnetic field due to the environment or the electromagnetic field from the circuits or motors. The experiments showed that the south-pointing chariot can be effectively used to detect the change of the orientation of the mobile platform while it is moving. The information provided by the south-pointing chariot can be used to control the platform to move along a straight line, or rotate to a desired angle.
