[0003] Most of the existing autonomous charging technologies for mobile robots use contact-type wired charging, usually with the help of laser detectors, visual sensors or infrared detection to mechanically dock with the charging equipment. The wired method requires the metal contact point between the robot and the charging stand to be exposed Externally, there are problems such as reliability, maintainability, and electrical safety, and there is a problem that the robot pushes the charging stand during the docking process and cannot be docked accurately

Abstract
The invention relates to the technical field of intelligent control and discloses a wireless charging method and device for a mobile robot. The method comprises steps as follows: battery capacity of the mobile robot is monitored through a battery and power supply management module; when the battery capacity is lower than a preset threshold value of power capacity, a charging request is sent, and a secondary coil is arranged at the bottom of the mobile robot; the mobile robot is navigated to a charging base according to charging base position information preset in a map, and a primary coil is arranged on the charging base; the mobile robot is subjected to vision localization through the primary coil and the secondary coil, and docking deviation between the primary coil and the secondary coil is acquired; when the docking deviation is smaller than a preset deviation threshold value, the mobile robot is charged. Preliminary positioning can be realized through navigation, accurate positioning is performed through a vision camera, the robot is automatically and wirelessly charged without manual operation, and the charging efficiency is improved.
Description
technical field [0001] The invention relates to the technical field of intelligent control, in particular to a wireless charging method and device for a mobile robot. Background technique [0002] Robots are gradually entering the home and service industries, providing services directly to individuals, such as sweeping robots, welcoming meal delivery robots, customer service robots, security patrol robots, etc. When the robot is running low on power or the task is over, it will move to the configured charging device It can be recharged for long-term autonomous operation. [0003] Most of the existing autonomous charging technologies for mobile robots use contact-type wired charging, usually with the help of laser detectors, visual sensors or infrared detection to mechanically dock with the charging equipment. The wired method requires the metal contact point between the robot and the charging stand to be exposed Externally, there are problems such as reliability, maintainab...
