Mobile robots employ many types of onboard sensors to provide a variety of services. Meanwhile, the concept of a structured environment using RFID etc. has also been introduced. In these systems, the robot aims to obtain information from sensors which are located in the environment. However, actual environments are complicated and often there exist various static and dynamic obstacles. Especially when using only RFID, it is essential for the system to update RFID information according to environmental changes. This paper presents a device to update RFID information for object position changes. It consists of two parts; a system to transmit RFID information to the PC using Bluetooth, and an RFID reader to obtain location information in an indoor environment when detecting a passive RFID tag. The effectiveness of the proposed device is shown through mobile robot navigation under two conditions; with object position changes and without.
