Abstract
In EXPO 2005 AICHI JAPAN, we performed an experiment using intelligent wheelchair robots that were developed in the NEDO Project for the Practical Application of Next-Generation Robots. These robots can travel to destinations autonomously in the demonstration course. In order to travel autonomously, robots need to know their own position and direction accurately. We developed an integrated positioning unit which enables accurate position and direction determination using GPS, RFID and directional compass. This report introduces an outline of the integrated positioning unit and presents the results of the demonstration experiment which was performed at the EXPO site.
