Abstract

The invention belongs to the technical field relevant to mobile robot servo, and discloses a mobile robot RFID servo method based on positions. The method comprises the following steps of (1) randomlygenerating the preset quantity of particles in an existence position space of a target object; (2) continually collecting phase information of an RFID label on the target object by a RFID reader-writer arranged on a mobile robot, and further obtaining a practical measured value of a phase difference value; (3) processing sensor information so as to obtain the position information of a RFID antennae arranged on the mobile robot, and further obtaining a theoretical estimated value of the phase difference value; (4) performing calculation by a particle filter algorithm to obtain the position estimated value of the RFID label in the coordinate system of the current mobile robot; and (5) evaluating the stability of the position estimated value; and performing corresponding processing accordingto the evaluation result until the mobile robot and the target object reach the expected position relationship. The method has the advantages that the implementation is easy; and the applicability ishigh.

Description

technical field

[0001] The invention belongs to the technical field related to the servo of mobile robots, and more specifically relates to a position-based RFID servo method for mobile robots. Background technique

[0002] RFID (Radio Frequency Identification), also known as radio frequency identification, is one of the key technologies of the Internet of Things. Compared with barcodes and QR codes, it has the advantages of non-line-of-sight, long-distance, good anti-counterfeiting, and large amount of information. It is mainly used in supermarkets Identification and management of items in fields such as warehouses and warehouses. Combining RFID with mobile robots to form a mobile robot RFID servo system, this system can combine the advantages of a large working space of mobile robots with the unique ID identification characteristics of RFID, and realize the servo navigation control of mobile robots in a wide range of workspaces , which helps to improve the efficiency of i...
