Mobile robot self-charging system

Abstract

The invention relates to a mobile robot self-charging system comprising a main control board, a robot controller, a power supply module, a power monitoring module, a drive control module, a sensor board, a laser sensor, and an infrared sensor. The power monitoring module acquires power information of the power supply module. The robot controller controls the laser sensor to acquire a pulse signal containing charging station position information according to the power information. The main control board establishes a first travel path trajectory according to the pulse signal. The sensor board collects an infrared signal acquired by the infrared sensor. The main control board corrects the first travel path trajectory according to the infrared signal to obtain a second travel path trajectory. The mobile robot self-charging system provided by the invention is an intelligent mobile robot self-charging system composed of a laser scanning modeling technology, an infrared positioning technology and a robot motion control technology. The defect of sole dependence on the laser or infrared technology is overcome. The reliability and accuracy of robot self-charging are improved.

Description

technical field [0001] The invention relates to robot motion control technology, in particular to an autonomous charging system for a mobile robot. Background technique [0002] In the existing technology, there are mainly two ways to realize the autonomous charging of intelligent mobile robots. One is to use the combination of infrared ranging technology and motion control technology to realize autonomous charging; the other is to use laser modeling technology combined with motion control technology Combined to achieve autonomous charging. However, the above two technologies have the following defects in practical application: (1) When using infrared ranging technology to realize autonomous charging, it mainly uses infrared reception combined with attitude adjustment strategy, which causes the robot to be far away from the charging station. Constantly adjusting the posture, it is impossible to determine the location of the charging station in a short period of time, and ch...

Problems solved by technology

However, the above two technologies have the following defects in practical application: (1) When using infrared ranging technology to realize autonomous charging, it mainly uses infrared reception combined with attitude adjustment strategy, which causes the robot to be far away from the charging station. Constantly adjusting the posture, it is impossible to determine the location of the charging station in a short period of time, and charging is too time-consuming; (2) When using laser modeling technology for autonomous charging, the robot can quickly lock the location of the charging station in a long-distance area, but in a short distance During precise alignment, due to the blind spot of the laser sensor's viewing angle, there may be position deviation during the alignment process
