Disclosed is a cleaner. The cleaner includes a cleaner body, a suction nozzle configured to suck dust on a floor surface, and a suction hose configured to transfer the dust, transferred from the suction nozzle, to the cleaner body. The cleaner body includes a driving driver or motor moving the cleaner body, a depth sensor configured to obtain image information about an object near the cleaner body, and a processor configured to extract a foot sole region of a person, based on the obtained image information, obtain a moving point of the cleaner body, based on the extracted foot sole region, and control the driving driver to move the cleaner body to the obtained moving point.

Robot for automatically following a person

The present disclosure discloses a robot cleaner, including a cleaner body; and a sensing unit disposed in the cleaner body, wherein the sensing unit includes a rotating body configured to be horizontally rotatable around a rotation shaft passing through an inside of the cleaner body; a sensing unit mounted on one side of the rotating body to sense a feature or an obstacle in the vicinity of the cleaner body; and a tilting unit installed inside the rotating body to vertically tilt the sensing unit.

Robot cleaner

A moving robot includes a travelling unit to move a main body, an image acquisition unit to acquire an image around the main body, a sensor unit including at least one sensor to sense an obstacle during moving, a storage unit to store information on a location of the sensed obstacle and information on a location of the moving robot, to register, into a map, an obstacle area of the obstacle, and to store an image from the image acquisition unit in the obstacle area, an obstacle acquisition module to determine a final attribute of the obstacle using the attributes of the obstacle obtained based on machine learning, and a control unit to detect attributes of obstacles through the obstacle recognition module if detecting a confinement state by the obstacles and to control the traveling unit to move one of the obstacles.

Moving robot and control method thereof

A moving robot includes a main body, a driving unit moving the main body, a camera installed on one side of the main body and capturing an image related to a marker, a memory storing information related to a pattern of the marker, and a controller extracting information related to at least one longitudinal line segment included in an appearance of the marker from the captured image, detecting information related to a position and a posture of the main body on the basis of the extracted information related to at least one of the longitudinal line segment and the pattern, and controlling the driving unit on the basis of at least one of the detected position and posture of the main body.

Mobile robot and method of controlling same

A robot cleaner includes a main body, a traveling unit, a cleaning unit, a sensor unit, and a controller. The traveling unit allows the main body to travel. The cleaning unit suctions foreign substances around the main body during the traveling. The sensor unit is rotatable and senses an obstacle using light reflected or scattered by the obstacle. The controller controls the traveling unit so as to travel along a traveling path and controls the cleaning unit so as to perform cleaning. Here, the sensor unit includes a first mode and a second mode that are set to differ from each other in sensitivity with respect to the reflected or scattered light, and the controller changes the sensitivity of the sensor unit according to a traveling mode.

Robot cleaner and method of operating the same

The present description relates to a robot cleaner and to a method for controlling the same, which involve generating a map of an area to be cleaned in accordance with a travel mode command, and performing a cleaning operation by avoiding obstacles on the basis of the generated map upon receipt of a cleaning mode command. For this purpose, the robot cleaner of the present invention comprises: a travel unit which travels around the area to be cleaned upon receipt of the travel mode command; a detection unit which detects an object located in the area to be cleaned during travel performed in accordance with the travel mode command; and a control unit which generates a map of an area to be cleaned on the basis of the information on the location of an obstacle, if the detected object is the obstacle, and controls a cleaning operation on the basis of the generated map upon receipt of a cleaning mode command.

Robot cleaner and method for controlling the same

Disclosed are a robot cleaner and a method for controlling the same. The robot cleaner and method of the present invention involve dividing the whole area to be cleaned into sub-areas, and easily calculating a full path using travel paths in the sub-areas and connection points between sub-areas, and in the event the whole area to be cleaned is extended or an area which has not been cleaned is found, do not involve regenerating the whole map for cleaning, but rather easily updating the full path using the pre-stored travel path in the sub-areas and the connection points between sub-areas.
