Disclosed is a robot cleaner. The robot cleaner of the present disclosure comprise: a gas sensor which is disposed inside the robot cleaner and senses suctioned air; and a processor which identifies contaminants on the basis of a sensing value of the gas sensor, and controls the robot cleaner so that the robot cleaner travels while avoiding the identified contaminants.

A robot cleaner includes a display unit, a camera unit configured to capture an image of a cleaning region when cleaning starts, a dust sensor configured to output a sensed signal corresponding to an amount of dust sucked in the cleaning region, and a control unit configured to calculate the amount of dust based on the sensed signal, to start an augmented reality (AR) mode when cleaning ends, to generate an AR image corresponding to the amount of dust, and to control the display module to superimpose the AR image on the image.

A robot for clearing snow has a main body; a traction arrangement enabling motion of the robot on snow lying on a roof; a snow-removal device; and at least one depth sensor. A processing and control unit controls at least one motor to direct the robot to follow a snow-clearing path; receives a depth signal from the depth sensor(s); and, as a function of the depth signal, actively controls a snow-clearing depth by actuating the snow-removal device and, as the robot follows the snow-clearing path, adjusting a vertical snow-clearing distance so as to leave a layer of snow of a pre-determined depth on the roof after clearing and to prevent contact by the snow-removal device with a surface of the roof. During snow removal, no part of the snow-removal device contacts the roof surface other than at most the traction arrangement.

A control method for a self-moving device controls the self-moving device to move in a designated area to process a predetermined object in the designated area. The method includes steps of: obtaining, during the moving process of the self-moving device, an image of an area in a forward direction of the self-moving device; and determining, according to the image, whether the predetermined object in the area in the forward direction of the self-moving device includes a specific predetermined object, so as to control a moving direction of the self-moving device. The specific predetermined object and the predetermined object have at least one different feature parameter. A related self-moving device is also disclosed.

An autonomous work machine including a working unit, the autonomous work machine comprising: a detection unit configured to detect a rear work target object of the autonomous work machine; a determination unit configured to determine a state of the rear work target object based on a detection result of the detection unit; and a control unit configured to control a travel route of the autonomous work machine based on a determination result of the determination unit.

A method includes receiving sensor data collected by an autonomous mobile robot as the autonomous mobile robot moves about an environment, the sensor data being indicative of sensor events and locations associated with the sensor events. The method includes identifying a subset of the sensor events based on the locations. The method includes providing, to a user computing device, data indicative of a recommended behavior control zone in the environment, the recommended behavior control zone containing a subset of the locations associated with the subset of the sensor events. The method includes defining, in response to a user selection from the user computing device, a behavior control zone such that the autonomous mobile robot initiates a behavior in response to encountering the behavior control zone, the behavior control zone being based on the recommended behavior control zone.

A cleaning robot that performs cleaning while travelling a space to be cleaned, the cleaning robot including: a travelling unit that moves the cleaning robot; a cleaning unit that cleans the space to be cleaned; an image capturing unit that captures an image viewed from the cleaning robot; a voice input unit to which a user's voice instructions are input; and a controller obtaining the user's motion instructions through the image capturing unit and determining a restricted area in which entry of the cleaning robot is prohibited and/or a focused cleaning area to be intensely cleaned by the cleaning robot based on the user's motion instructions or the user's voice instructions when the user's voice instructions are input through the voice input unit. The restricted area and the focused cleaning area may be input to the cleaning robot through the user's voice and motion.
