자이로 센서를 이용한 RFID 기반 위치인식 기술

In-door service Robots do not work in fixed tasks as do industrial robots because it is together with humans in the same indoor space but has to work in much more flexible and diverse environments. One of the most fundamental pieces of information that is needed is the positional )localization) information of but these sensors cannot sense objets through obstacles (viz., the line-of-sight problem). Recently, ubiquitous localization offers helpful services anytime and any where by using real-time location information of objects based on ubiquitous network. There have been a few attempts to apply RFID in Ubiquitous localization. FRID does not suffer from the line-of-sight problem, and its object ID and be trivially retrieved. However, today’s FRID technology does not provide enough accuracy in distance measurement and especially the posture information. Therefore, in this paper, we suggest a new way of gyro-sensor, accurate posture information of mobile robot is acquired. We construct a Self-localization system based RFID co-working with gyro-sensor and investigate how localization technique can be enhanced by RFID through experiment to measure the location of a mobile robot.
