Automatic charging system and automatic charging method for robot

Abstract

The invention provides an automatic charging system for a robot. The automatic charging system for the robot comprises an infrared transmitting tube, infrared receiving tubes, a DSP (digital signal processor) controller, an edge guiding module, an angle compensating module and a charging module; and the infrared receiving tubes are arranged in the front of the robot and at the rear of the robot. According to the automatic charging system and an automatic charging method for the robot in an embodiment, the single infrared transmitting tube is used for transmitting infrared signals, the edge characteristics of an infrared transmitting range are skillfully used, and butt joint guidance on the robot can be implemented by an angle compensation strategy. Because edge angle characteristics of different infrared transmitting tubes are different, when the automatic charging system is used for the first time, a tangent angle of the transmitting angle at a transmitting point requires to be measured manually. Even if an approach angle has deviation due to external interferences, a charging head is within a range of a charging socket through the angle compensation strategy. Deviation of an inserting angle can be compensated through a mechanical structure of a charging station. In addition, the invention also provides an automatic charging method for the robot.

Description

technical field [0001] The invention relates to the technical field of robot charging, in particular to a robot autonomous charging system and method. Background technique [0002] With the continuous improvement of automation technology, people's demand for automation and intelligence of living facilities is getting higher and higher. In recent years, various life service robots have sprung up in the market, such as cleaning robots, tour guide robots, and consulting robots. These robots have some common characteristics, such as small and fixed range of motion, and poor battery life. Therefore, the automatic charging technology came into being. When the robot's power is low, the robot is guided to the charging station by itself in a certain way, and then automatically starts working after charging. This eliminates the need for frequent manual charging. [0003] In the prior art, methods for indoor navigation mainly include laser navigation, ultrasonic detection, infrared ...

AI Technical Summary

Problems solved by technology

Therefore, the robot manufactured by existing technology has a low success rate in the process of automatic charging guidance, which requires multiple attempts and adjustments, and even the robot is very close to the charging station but has not been able to complete the guidance.

Some technologies use infrared ranging technology to test the distance according to the phase of the received echo. The receiving strength of this method is susceptible to external interference, and the equipment cost of the phase difference can be judged.
