Robot automatic charging system and charging method thereof

Abstract

The invention discloses a robot automatic charging system and a charging method thereof. The system comprises a power monitoring unit, an infrared signal receiving unit, an infrared distance measuring unit, a wireless signal transceiver unit, a visual recognition unit, a robot control unit, and a motion system unit, wherein the robot control unit is connected with the power monitoring unit, the infrared signal receiving unit, the infrared distance measuring unit, the wireless signal transceiver unit, the visual recognition unit and the motion system unit. According to the invention, an infrared signal tracking method and an image identification method are combined together. By fusing originally single methods, problems occurring in tracking using only one method are solved. Thus, a robot can accurately and stably find a charging pile for charging without environmental interference.

Description

technical field [0001] The invention relates to a robot, in particular to a robot automatic charging system and a charging method thereof. Background technique [0002] At present, the development of robots is very rapid, and their functions are also increasing day by day. However, robots often encounter the problem of insufficient battery power when they are working. This is because the robot needs human hands to operate to help the robot continue its battery life. This makes the robot receive power when performing work. limit. In order to reduce the problem of manual battery life for robots, research on autonomous charging of robots has become a major direction for the development of robots. For the autonomous charging of robots, there are roughly three existing solutions at home and abroad: infrared signal tracking, radio frequency wireless tracking, and image recognition methods. [0003] For the autonomous charging of robots, there are roughly three existing solutions...

AI Technical Summary

Problems solved by technology

Infrared signal tracking is to find the location of the charging pile through the infrared signal sent out and then dock, but the docking location is often not accurate enough and prone to deviation; radio frequency wireless tracking is to judge the location of the charging pile based on the strength of the emitted radio frequency signal, but it can only Roughly find the location of the charging pile; and the image recognition method uses the camera to perform related image processing to find the charging pile, which is also easily affected by the environment

To sum up, the main problems of autonomous charging of robots at present are that the location of the charging pile is not accurate enough, the safety is low, and it is easy to be disturbed by the environment.
