Abstract: A system and a method for recognizing a current position of a mobile robot with RFID(Radio Frequency IDentification) are provided to enable the autonomous mobile robot to recognize the current position correctly and quickly in a remote place by transceiving a UHF(Ultra High Frequency) band signal with RFID tags installed in a predetermined space and adjusting RFID transmission power. An RFID tag(100) stores ID/location information of a moving path, and retransmits a UHF band signal in a reflection wave form and generates DC power by receiving the UHF band signal from a mobile robot(200). The mobile robot moves along a predetermined path and performs an ordered operation by checking a current position based on the ID/position information received from the RFID tag. The mobile robot includes an RFID reader(210) transmitting the UHF band signal to the RFID tag, obtaining the position information including intensity, a reception time, and a reception direction of the signal by demodulating the signal received from the RFID tag, and transmits the UHF band signal after attenuation or amplification, a robot controller(220) measuring the distance and the direction from the RFID tag by calculating the current position, a transmission power generator(230), a robot memory(240), a robot driver(250), and antenna(260).
