The embodiment of the present disclosure provides a robot control method, a robot and a storage medium. In the embodiment of the present disclosure, the robot determines a position when the robot is released from being hijacked based on relocalization operation; determines a task execution area according to environmental information around the position when the robot is released from being hijacked; and afterwards executes a task within the task execution area. Thus, the robot may flexibly determine the task execution area according to the environment in which the robot is released from being hijacked, without returning to the position when the robot is hijacked, to continue to execute the task, then acting according to local conditions is realized and the user requirements may be met as much as possible.

A robot cleaner according to an embodiment of the present disclosure includes: a light receiving sensor configured to measure a brightness of a floor surface; an illumination part configured to irradiate the floor surface with light; a rotation device connected to the illumination part and configured to adjust a rotational angle of the illumination part; an capturing part configured to capture an image of the floor surface; a memory part that stores the image of the floor surface captured by the capturing part; a driving part including an electric motor and wheels; a vacuum suction part configured to perform a vacuum suction by being supplied with power from the electric motor; and a control part. The control part determines an operation in a capturing mode in the capturing mode and a cleaning mode when a value input from the light receiving sensor is determined to be equal to or lower than a predetermined value.

The present disclosure provides a control method capable of, by using a current value of a nozzle, determining whether a nozzle is separated from a vacuum cleaner and whether the nozzle is reconnected to the vacuum cleaner after separation. To this end, a vacuum cleaner may comprise a nozzle connectable to a suction unit for suctioning dusts. The nozzle may comprise a rotary cleaning unit for applying pressure to a cleaning target surface so as to separate a foreign substance therefrom, and a nozzle motor for driving the rotary cleaning unit. In order to drive the nozzle, a voltage having been controlled by a pulse width modulation (PWM) method is applied, and a measurement unit included in the vacuum cleaner may measure a current value of the nozzle, the current value depending on the applied voltage.

Provided is a robot cleaner including a main body including a suction portion disposed thereon, main wheels for moving the main body, a side brush assembly disposed on the main body and rotating with a rotation shaft perpendicular to a rotation shaft of the main wheels, wherein the side brush assembly includes a housing for forming an exterior of the side brush assembly, a first force transmitter disposed in the housing and rotating by receiving a driving force, a second force transmitter in contact with the first force transmitter to rotate together when the first force transmitter is rotated, and a side brush coupled to the second force transmitter to rotate at the same rotation angle as the second force transmitter.

Embodiments of the disclosure relate to a robot cleaner and a controlling method thereof, and more particularly, to a robot cleaner and a traveling algorithm of a robot cleaner having an improved structure. A robot cleaner of the disclosure includes a brush unit having a suction flow path, a body unit configured to have a driving device, and be coupled to the brush unit to be rotatable with respect to the brush unit and a redirection device configured to rotate the body unit relative to the brush unit, and the redirection device includes a rotation guide extending along an inner circumferential surface of the brush unit, a rotation driving source disposed in the body unit and generating power, and a power transmission member which moves along the rotation guide by the power transmitted from the rotation driving source and rotates the body unit with respect to the brush unit.

A cleaner, according to one embodiment of the present invention, comprises: a cleaner main body comprising a suction motor, a dustbin and a battery; a suction nozzle having formed thereon an opening part for suctioning in external air; and an extension tube for connecting the cleaner main body and the suction nozzle. The suction nozzle comprises: a housing forming the exterior and the opening part of the suction nozzle; a rotational cleaning unit accommodated in the housing and cleaning a surface being cleaned by means of a rotational operation; a motor inserted in one side of the rotational cleaning unit so as to rotate same; a suction nozzle battery for supplying power for driving the motor; and a wireless power receiving unit connected to the suction nozzle battery so as to provide same with power supplied by an external wireless power transmission unit.

A floor treatment appliance with a replaceable change component, a detection device for detecting an actual parameter that is influenced by wear of the change component, an evaluation device for determining a degree of wear of the change component based on the actual parameter and a communication device for communicating information concerning a required replacement of the change component to an external terminal that is communicatively linked to the floor treatment appliance. The change component is a floor treatment element that mechanically acts upon a floor surface to be treated, and the evaluation device calculates an average value of the actual parameter detected by the detection device referred to a defined time period of at least one hour, compares the average value with a defined reference value and determines the degree of wear of the change component in dependence on the result of the comparison.

The invention is in the field of a cleaning machine for a road or pavement or gutter. These machines are used to remove objects, such as small items, such as leaves, and dirt from a road or the like, using a broom system for cleaning the road or the like, and typically a storage for removed objects and dirt.

Disclosed are a cleaning module and a cleaner comprising same. The cleaning module, according to one aspect of the present specification, comprises: a housing communicating with a suction port of a main body of the cleaner, and comprising a suction space exposed to a bottom surface; a first hole disposed on one side surface, perpendicular to a cleaning direction, of the housing; and a first opening/closing device comprising a first shielding member for enabling communication with the suction space by selectively opening/closing the first hole.

Provided is a method for controlling a robot cleaner including a first operation of identifying that a manual cleaner and the robot cleaner are turned on, a second operation of identifying, by the robot cleaner, a location of the manual cleaner, a third operation of moving, by the robot cleaner, to a location within a first set distance from the manual cleaner, and a fourth operation of stopping the movement of the robot cleaner when the robot cleaner is located at the location within the first set distance from the manual cleaner while the manual cleaner is moving, and performing, by the robot cleaner, cleaning while moving when the robot cleaner is located at a location within a second set distance from the manual cleaner.
