Abstract

The invention discloses a charging method of a mobile robot. The charging method comprises the following steps of S1, detecting a charging seat by a laser radar or an infrared signal when the mobile robot is in a non charging-back state; S2, adding position information of the mobile robot when the charging seat is detected or position information of the charging seat into a map by the mobile robot; S3, seeking a position of the charging seat by the mobile robot according to the map; and S4, achieving aligned charging-back with the charging seat by the mobile robot according to an infrared charging-back signal. The position information of the mobile robot or the position information of the charging seat when the charging signal is detected is added into the map, the charging seat is sought according to the map information when charging-back is required by the mobile robot, the mobile robot can be rapidly navigated to a part near to the charging seat, alignment is performed by an infrared positioning mode, and the charging method has the advantages of rapid charging-back and high alignment accuracy. Moreover, the invention also discloses a charging system of the mobile robot.

Description

technical field [0001] The invention relates to mobile robot technology, in particular to a charging method and a charging system for a mobile robot. Background technique [0002] With the development of science and technology, mobile robots can be used in various occasions to replace manpower to complete various tasks. Work, efficiently complete various tasks in an effective space and time, and is currently widely used in logistics, detection, service and other fields. [0003] Existing mobile robots generally use rechargeable batteries to provide power, and the continuous power supply time that rechargeable batteries can provide is relatively short, and the general running time exceeds 2 or 3 hours, and it needs to be charged. How to design a reasonable recharging algorithm to make the mobile robot complete automatic recharging when the battery is insufficient has become one of the challenges that the mobile robot faces. [0004] At present, the automatic recharging sche...
