Information distributed description based on Radio Frequency Identification

Artificial landmarks are the effective means for reducing the mapping difficulty autonomously in unknown environment. However, the artificial landmark used currently only gives the position information, can´t provide some semantic information of the environment such as name, function, context, and so on. Even though artificial landmarks are used in the environment, map building is still the prerequisite of work completion. This paper introduces a information distributed description mode based on RFID technology, which changes the traditional mode that the robot should build map first. Basing on the optimizing layout strategy, RFID labels are distributed at the key points of the environment. The semantic information, context information and navigation information are stored in the RFID labels. Although the robot knows nothing about the environment, the robot can get to the target position with the guide of RFID labels, realize the navigation withoult the environment map.
