In real life, looking for a misplaced object like a key in the room can be usually like searching for a needle in a haystack. In this paper, we propose a novel solution to accurately locate the specified objects attached with RFID tags in indoor environments, by efficiently leveraging the RFID technology. By making a number of novel observations regarding the tag reading performance, we obtain several...
In this paper, we describe an autonomous navigation system for a mobile robot using randomly distributed passive RFID tags. Furthermore, in order to acquire the robot's location and orientation precisely, we developed the read-time model. According to the conventional approaches, more than two readers are required to estimate the orientation of the robot when using a passive RFID system. With our...
In this paper, we propose a novel method using read-time of IC tags to reduce the localization error of an RFID navigation system. In order to reduce localization error, many approaches have been introduced. However, they do not deal with the problems that arise when the antenna can read at most one tag at any given moment. Using this, our passive RFID system is able to estimate the robot's location...
This paper proposes an efficient method for localization and pose estimation for mobile robot navigation using passive radio-frequency identification (RFID). We assume that the robot is able to identify IC tags and measure the robot's pose based on the relation between the previous and current location according to the IC tags. However, there arises the problem of uncertainty of location due to the...
