Technique to correct the localization error of the mobile robot positioning system using an RFID

Localization of objects is one of the most important fundamental technology to realize ubiquitous network technology. To realize localization of objects, we construct an absolute positioning system based on RFID and investigate how localization technique can be enhanced by an RFID system through experiments to measure the position and moving direction of a mobile robot. Moreover localization error is caused by long processing time which is spent on estimation of the position and direction. Error compensation is executed for improving the accuracy of measurement.
