  • Patent number: 11605244
    Abstract: 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.

  • Publication number: 20210138640
    Abstract: An embodiment provides a robot cleaner comprising: a driving module for moving a cleaner body within a first cleaning area; a camera module for outputting a first and a second image obtained by photographing a front-side environment when the cleaner body is moved; and a control module for, when the type of an obstacle located in the front-side environment is recognized on the basis of the first and second image, controlling the diving module to allow the cleaner body to move while performing an avoiding motion or a climbing motion on the basis of the type of the obstacle.

  • Publication number: 20210100416
    Abstract: The present disclosure relates to a robot cleaner having a filter for preventing the cleaner from being constrained by an obstacle. The robot cleaner has a constraint prevention filter arranged to face the front with respect to an agitator, and thus the robot cleaner may be prevented from being constrained as a result of an obstacle being stuck on a cleaning nozzle. In addition, the present disclosure relates to a depth sensor control system enabling the depth of an object to be accurately measured by controlling the amount of light received by a sensor. The depth sensor control system measures, at a light-receiving part, the intensity and frequency of an infrared (IR) ray reflected from an object, and controls the amount of light based on a histogram created using the measurement, and thus enables depth information of an object to be accurately measured without using separate additional equipment.

  • Patent number: 10852729
    Abstract: 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.
