Mobile robot and charging system and charging control method thereof

Abstract

The invention provides a mobile robot and a charging system and charging method thereof. The mobile robot comprises a controller, and also comprises an electrical quantity monitoring device, a mobile drive device, a signal strength monitoring device, a radio receiving device, a wireless charging module and an electric energy storage module which are all connected with the controller. The charging control method comprises the steps that the controller sends a remnant electrical quantity acquisition instruction to the electrical quantity monitoring device when receiving a motion instruction from a user; when the electrical quantity is small, the controller sends a current position radio signal strength acquisition instruction to the signal strength monitoring device, the radio signal strength variation rate is calculated, and the moving parameters of the mobile drive device are set according to the obtained radio signal strength variation rate; and when the obtained radio signal strength variation rate meets the set variation threshold value, an operating instruction is sent to the radio charging module. By adoption of the wireless charging mode, precise positioning and charging port inserting are not needed, abrasion of charging equipment can be avoided, the service lives of a charger and the charging port of the mobile robot are prolonged.

Description

technical field [0001] The invention relates to the technical field of automatic control, in particular to a mobile robot, a charging system and a charging control method thereof. Background technique [0002] With the development of science and technology, mobile robots can gradually replace human beings to undertake simple and repetitive physical labor. A considerable part of these robots must have their own batteries to achieve mobility. When the battery is exhausted, the robot will not be able to work. Therefore, it is necessary to monitor the power of the robot from time to time. When the charging command is activated, the robot must start the mode of searching for the charging station in order to return to the charging station in time for charging. [0003] The existing mobile robot charging control system mostly establishes the connection between the charger and the mobile robot through different communication positioning methods, so that the mobile robot can underst...

AI Technical Summary

Problems solved by technology

[0004] In the process of realizing the positioning of the above-mentioned system, the mobile robot needs to continuously correct the position through the infrared sensor array. The reciprocating multiple positioning not only wastes time and consumes power, but also easily causes wear on the metal contacts when trying to insert the charger. Affect the service life of the charger
