This paper describes a novel strategy to Radio-Frequency Identification (RFID) tag detection\nfor humanââ?¬â??robot interaction (HRI) purposes. The anisotropic detection pattern of the RFID reader\nantenna is combined with a probabilistic algorithm to obtain a coarse angular position relative to the\nRFID reader that can be used, for example, for behavioral control based on proxemics areas around\nthe robot. The success rate achieved is suitable for HRI purposes. The paper presents experimental\nresults on a detection model for the reader.
