Problems solved by technology

[0005] However, since the conventional method is implemented by random travel, there are different times for returning to the charging stand according to the position of the cleaning robot
In the conventional method using random marching, if it takes a long time to detect artificial marks attached to the charging stand, when returning to the charging stand, the power supply voltage charged in the battery may all drop, thereby stopping the driving of the cleaning robot

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...
