Reliable and efficient RFID-based localization for mobile robot

This paper proposes a precise and low cost localization system for mobile robots by using Radio Frequency Identification (RFID) module and RFID tags. The localization system consists of the RFID reader, the RFID tags, a mobile robot and an off-board computer. The proposed system is developed to solve the problems of localization and guiding for mobile robots at home, service, industrial and defense applications by tracking RFID tags, analyzing received signal strength indication and taking other metric into consideration. The critical metric is the velocity of mobile robot, which has significant influence on localization system and is the novel feature for the localization system. Multiple regression model and fuzzy logic are compared to locate the mobile robot. The experiment results demonstrated that the fuzzy logic system can be used to build localization system to locate mobile robots more accurately than multiple regression model. This paper illustrates the design and performance analysis of low cost and high accuracy localization system.
