A study of intelligent drawer with RFID tag information reading system for Intelligent Space

People store many things in drawer cases. However, they sometimes forget the places of the stored things. As a solution of this problem, we propose a managing system which server stores and informs the place of the stored things by using the idea of "Intelligent Space". Home service robot is able to use this system for getting information of stored things and bring them to the user. The system consists of drawer case, RFID tag, tag antenna and tag reader. RFID tag is attached to the stored things. Tag antenna reads RFID tag data and gets information of the things. In this system, reliability of RFID tag reading is especially important. However, the stored things in the drawer case are vary and the positions and orientations of the attached RFID tags are different according to the posture and the shape of the stored things. It is necessary to be read RFID tags of various positions and orientations in this system. In this paper, we consider the method to read RFID tags of various positions and orientations. Especially, we consider reading the vertical RFID tags in regard to tag antennas. We made a prototype model of drawer case, and evaluated it through experiments.
