A vacuum cleaner for performing autonomous driving may include: a main body; a driving unit; a suctioning unit; a plurality of sensors for sensing obstacles present in each direction; and a control unit for controlling the driving unit to move the main body on the basis of a preset driving pattern. The control unit uses sensors provided at the front side of the main body and a first side of the both sides of the main body so as to detect whether entry into a corner area among cleaning areas is made while driving along the preset driving pattern, and controls the driving unit such that the first side of the main body comes into contact with a first wall forming the corner area at least one time when the main body enters the corner area.

Vacuum cleaner and control method therefor

A robot cleaner comprising: a cleaner body including a controller, the cleaner body having a dust container accommodation part formed therein; a wheel unit mounted in the cleaner body, the wheel unit of which driving is controlled by the controller; and a dust container detachably coupled to the dust container accommodation part, wherein a first opening and a second opening are disposed at the same height in an inner wall of the dust container accommodation part, wherein the dust container includes: an entrance and an exit, disposed side by side along the circumference of the dust container, the entrance and the exit, respectively communicating with the first opening and the second opening when the dust container is accommodated in the dust container accommodation part; and a flow separating part extending downwardly inclined along the inner circumference of the dust container.

Autonomous cleaner

In order to solve the problem of the present invention, a vacuum cleaner that performs autonomous driving according to an embodiment of the present invention is characterized by comprising: a main body; a driving unit for driving the main body; a camera for detecting 3-dimensional coordinate information; a memory for storing pattern information related to a recharging station; and a control unit which compares the 3-dimensional coordinate information detected by the camera and the pattern information stored in the memory and related to the recharging station, and which determines, on the basis of the comparison result, whether or not the recharging station is positioned in the vicinity of the main body.

Vacuum cleaner and method for controlling same

A robot cleaner may determine a climbable low height obstacle such as a threshold, a carpet, or the like in a cleaning area when the robot cleaner travels the cleaning area. The robot cleaner may be able to climb the obstacle after completing a travel of a region except for the corresponding obstacle.

Robot cleaner and method for controlling the same

A robot cleaner includes a controller configured to sense an obstacle with a sensing unit of the robot cleaner, and control a driving unit of the robot cleaner to move a main body of the robot cleaner forward into a first contact state in which a front end of a cleaning unit cleans a first region while in contact with the obstacle. After the first contact state, the controller controls the driving unit to move the main body according to a predetermined connecting operation into a second contact state in which the front end of the cleaning unit cleans a second region while in contact with the obstacle, the first region and the second region being arranged along an outline of the obstacle.

A mobile robot system and a related control method sets a virtual wall as a specific area so that a mobile robot cannot approach within a cleaning area to restrict a traveling of the mobile robot, registers the virtual wall on a map when the virtual wall for restrict the approach of the mobile robot is set by a terminal, calculates a location of the virtual wall for the cleaning area to avoid the virtual wall, and restricts the approach of the mobile robot by matching the virtual wall to the cleaning area, controlling the mobile robot as if an actual physical obstacle exists by setting the virtual wall on the map through the terminal and matching to an actual cleaning area, and achieving an easy cleaning setting and effectively controlling the mobile robot as it can be plurally set at a desired location irrespective of the number.

Mobile robot system and control method thereof

A robot cleaner comprising: a cleaner body including a controller, the cleaner body having a dust container accommodation part formed therein; a wheel unit mounted in the cleaner body, the wheel unit of which driving is controlled by the controller; and a dust container detachably coupled to the dust container accommodation part, wherein a first opening and a second opening are disposed at the same height in an inner wall of the dust container accommodation part, wherein the dust container includes: an entrance and an exit, disposed side by side along the circumference of the dust container, the entrance and the exit, respectively communicating with the first opening and the second opening when the dust container is accommodated in the dust container accommodation part; and a flow separating part extending downwardly inclined along the inner circumference of the dust container, the flow separating part separating the flow of air introduced into the entrance from the flow of air discharged toward the exit to be respectively guided to lower and upper portions thereof.

A mobile robot of the present disclosure emits a first patterned light downward and forward from a main body on a floor of an area to be cleaned and a second patterned light upward and forward from the main body, determines an obstacle based on an image of each emitted patterned light which is incident on the obstacle, and senses a tilt of the main body to compensate for the tilt. In this manner, an obstacle may be determined accurately, and after the tilt compensation, redetermination is made as to whether it is possible to pass through, so as to enable the mobile robot to pass through or bypass the obstacle. Accordingly, the mobile robot may reach a wider area to be cleaned, thereby extending the area that may be cleaned, and enabling fast determination and operation for effective traveling, such that the mobile robot may escape from an obstacle without being limited thereby.

Mobile robot and method for controlling and detecting inclination using pattern light

A robot cleaner comprising: a cleaner body including a wheel unit for autonomous traveling and a suction unit sucking air containing dust; a sensing unit disposed at one side of the cleaner body; a dust container accommodated in a dust container accommodation part formed at the other side of the cleaner body, the dust container collecting dust filtered from sucked air; and a dust container cover disposed to cover a top surface of the dust container, wherein an upper end of the sensing unit is formed at a position protruding upward from a top surface of the cleaner body and a top surface of the dust container cover.

A mobile robot of the present disclosure includes a first pattern emission unit configured to emit a first patterned light downward and forward from the main body on a floor of an area to be cleaned; and an image acquisition unit configured to acquire an image of first patterned light emitted by the first pattern emission unit and incident on an obstacle. A pattern is detected from the acquired image to determine an obstacle, and a cliff is detected based on at least one of a shape or a position of the pattern in the image. The mobile robot may identify a travel path that does not lead to the cliff.
