Method and device for autonomous charging of mobile robot

Abstract

The invention provides a method and device for autonomous charging of a mobile robot; and the method comprises the steps: obtaining point cloud data of radar scanning of one side, facing a charging pile, of a mobile robot at a detection position, dividing the point cloud data into a plurality of point cloud subsets, wherein the charging pile comprises a specific shape structure; matching each point cloud subset in the plurality of point cloud subsets with a point cloud template corresponding to the specific shape structure, and determining position and direction information of the charging pile according to the matching result; and completing butt joint with the charging pile according to the position and direction information, and starting charging. According to the scheme of the invention, the method is wide in application range, is low in cost, is high in detection result precision, can achieve the safe butt joint, and is stable and reliable.

Taking the industrial field as an example, in recent years, mobile robot technology has played an increasingly important role in modern industry. Compared with traditional industrial production lines that rely on human transportation, production lines that rely on mobile robots for automated transportation have higher Accuracy and safety, and production efficiency will also be greatly improved. However, most of the existing charging technologies rely on laying magnetic tracks on the ground, arranging artificial signs such as QR codes in the charging environment, and installing infrared docking devices. The robot moves according to a set or semi-set path to dock with the charging pile. The way of laying the magnetic track and arranging the QR code requires daily maintenance, and when the factory environment changes, it needs to be rebuilt. The installation of an infrared docking device is costly and easy. error occured
