Obstacle Avoidance Scheme for RFID Based Mobile Robot in Libraries

Abstract

This paper proposes an obstacle avoidance scheme of a novel mobile robot system for automatic search of books in libraries based on the radio frequency identification (RFID). Nowadays, most of the libraries utilize the barcode identification technique, since it is of low cost. However, our experiments show that using RFID adequately can save more labor and improve the library management efficiency, since RFID has many advantages, i.e., large information storage and long identification distance, etc., whose application in library management information system has great development potential. Based the advantages of its long-distance identification ability combined with the close accurate positioning technologies, an intelligent mobile robot system for automatic search of books anywhere in libraries is design in our project, which can effectively improve the book search efficiency, saves the massive cost and improve the library informatization level. According to this mobile robot, we give a fuzzy multisensor fusion technique based obstacle avoidance method, which can make the intelligent robot searching the desired books automatically in libraries. Both the simulation and the actual experiments validate the obstacle-avoiding algorithm.
