Positioning and Navigation of Meal Delivery Robot Using Magnetic Sensors and RFID

The main purpose of this paper is to study positioning and navigation of mobile robot with integrated magnetic sensor and RFID. With the use of RFID and the proposed progressive polling algorithm, process the data access and identification for each Tag in order to prevent conflicts between read of Tag and ID number to improve efficiency. Through actual experiment results, mobile robot will move stably along a magnetic stripe. When one´s position offset, it will be corrected immediately. At this moment, RFID can exclude conflict between reads of Tags using progressive polling algorithm to keep the robot arrive accurately at the next station. Therefore, it provides a stability of platform to move the route, flexibility of the real-time correction of system platform, a high accuracy of positioning and navigation, and a high efficiency of Tag´s recognition.
