Problems solved by technology

[0007] However, in the case of using light patterns, it is difficult for the cleaning robot to recognize the light patterns according to the material of the floor area.
For example, in cases where light is absorbed by the floor area or direct light is provided around said floor area, it can happen that the camera of the cleaning robot cannot take an image including the light pattern

Abstract

In order to achieve the objective of the present invention, a self-driving vacuum cleaner according to one embodiment of the present invention, comprises: a main body for traveling through a cleaningarea and sucking foreign substances from the floor in the cleaning area; a drive unit for moving the main body in the cleaning area; a pattern irradiation unit, disposed on a front surface of the mainbody, for irradiating light in a predetermined pattern toward the lower front side of the main body; a camera, disposed on the front surface of the main body, for photographing the front of the mainbody; and a controller for detecting a light pattern formed by the pattern irradiation unit using an image photographed by the camera, determining whether an obstacle exists in front of the main bodyon the basis of the brightness of the detected light pattern, and controlling the drive unit to pass or avoid the obstacle on the basis of the determination result.

Description

technical field [0001] The present invention relates to a cleaning machine and a control method thereof, and more specifically, to a cleaning machine capable of identifying obstacles and performing autonomous travel and a control method thereof. Background technique [0002] Generally, robots have been developed for industrial use and have taken on part of factory automation. Recently, as robots are used in various fields, medical robots, space robots, etc. have been developed, and household robots that can also be used in general households are being developed and manufactured. [0003] A representative example of the home robot is a cleaning robot, a home appliance capable of cleaning by autonomously traveling in a predetermined area and sucking in surrounding dust or foreign matter. Such cleaning robots typically have rechargeable batteries and obstacle sensors that can avoid obstacles during travel, allowing them to clean while driving autonomously. [0004] Recently, ...
