| Summary: | Radio Frequency Identification (RFID) system allows automatic identification of
items with RFID tags using radio-waves. As the RFID tag has its unique identification number,
it is also possible to detect a specific region where the RFID tag lies in. Recently it is widely
been used in mobile robot navigation, localization, and mapping both in indoor and outdoor
environment. This paper represents a navigation strategy for autonomous mobile robot using
passive RFID system. Conventional approaches, such as landmark or dead-reckoning with
excessive number of sensors, have complexities in establishing the navigation and localization
process. The proposed method satisfies less complexity in navigation strategy as well as
estimation of not only the position but also the orientation of the autonomous robot. In this
research, polar coordinate system is adopted on the navigation surface where RFID tags are
places in a grid with constant displacements. This paper also presents the performance
comparisons among various grid architectures through simulation to establish a better solution
of the navigation system. In addition, some stationary obstacles are introduced in the
navigation environment to satisfy the viability of the navigation process of the autonomous
mobile robot. |
