Abstract

A cleaning robot, and more particularly a cleaning robot comprising a camera unit for photographing an external image containing the charging-stand image, converting it into electrical image information, and outputting externally; and a microprocessor for storing the image information inputted the camera unit, acquiring position information of the charging-stand from the external image on the basis of the image information of the charging-stand in detecting a return signal, and causing the cleaning robot to be returned to the charging-stand. The cleaning robot having an auto-return function to a charging-stand detects a direction and position of the charging-stand using image information of the charging-stand, and thereby correctly and rapidly returning to the charging-stand for the cleaning robot.

Description

technical field [0001] The present invention relates to a cleaning robot, and more particularly to a cleaning robot having a function of automatically returning to a charging-stand, wherein the cleaning robot can correctly and quickly return to the charging-stand of the cleaning robot using image information input from a camera, and a method of use thereof . Background technique [0002] A cleaning robot is a device that autonomously moves in a defined cleaning area such as a residence and an office, and sucks in dust or impurities. The cleaning robot includes components of a general purpose vacuum cleaner as well as other components. Here, other components include a traveling device for making the cleaning robot travel; many sensors for detecting collisions of the cleaning robot so that it runs without colliding with various obstacles; and a microprocessor for controlling the above-mentioned cleaning robot. member. As it moves autonomously within the cleaning area, the c...
