There is provided a cleaning robot including a light source module and an image sensor. The light source module projects a horizontal line pattern toward a moving direction. The image sensor captures, toward the moving direction, an image of the horizontal line pattern. The light source module is arranged below the image sensor so as to eliminate the interference from second reflection.

A cleaning method and a cleaning robot are provided. The method includes: after the cleaning robot obtains a cleaning instruction for a target scene, acquiring a current power of the cleaning robot and a scene map for the target scene; if it is determined that the current power is insufficient to clean all areas to be cleaned in the target scene, determining a target cleaning area from all the areas to be cleaned in the target scene, based on a target dirtiness level for each of the areas to be cleaned; cleaning the target cleaning area based on the scene map, the target dirtiness level for the target cleaning area and the current power. A more intelligent cleaning robot and a more reasonable cleaning process are realized.

A control apparatus for an auto clean machine comprising a light source configured to emit light to illuminate at least one light region outside and in front of the auto clean machine. The control apparatus comprises: a first image sensing area, configured to sense a first brightness distribution of the light region, wherein a resolution for a first direction of the first image sensing area is higher than a resolution for a second direction of the first image sensing area; and a processor, configured to control movement of the auto clean machine according the first brightness distribution.

A robot cleaner and a method of controlling the robot cleaner are disclosed. The robot cleaner may include a body, a mop, an actuator, a battery, a tank, and a controller. The controller controls a supply of liquid from the water tank to the mop, and the supply of the liquid may be controlled in consideration of a state of the battery. Water injection may be controlled according to an expected use time of the battery, such that the mop can maintain an appropriate water content, and uniform mopping and cleaning can be performed.

A robotic cleaner may include a body, an optical receiver, the optical receiver being configured to detect an optical signal generated by an external device, and an optical pattern generator configured to emit light according to an optical pattern that extends at least partially around the body, wherein, when the optical pattern intersects an obstacle, at least a portion of the light incident on the obstacle is reflected towards the optical receiver, the optical receiver being configured to detect the reflected light.

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 and a control method thereof are disclosed. A robot cleaner, according to an embodiment of the present invention, comprises: a tilt sensor module; a distance sensor module; and a light amount sensor module. Each piece of sensed information is transmitted to a lifting information calculation module. The lifting information calculation module calculates information on whether the robot cleaner is lifted, by using each piece of the transmitted information. If it is calculated that the robot cleaner is lifted off a floor, a power module is stopped. In addition, if it is calculated that the robot cleaner is not lifted off the floor, the power module is driven. Accordingly, when a user lifts the robot cleaner, injuries to the user caused by operation of a drive module can be prevented.

A robot vacuum cleaner and a control method therefor are disclosed. A robot vacuum cleaner according to an embodiment of the present invention comprises an acceleration change sensor module and a distance sensor module. Each piece of detected information is transmitted to an obstacle-passing information calculation module. The obstacle-passing information calculation module uses each piece of transmitted information so as to calculate information about whether an obstacle is present on one side of the robot vacuum cleaner and information about whether the robot vacuum cleaner can pass the obstacle on the one side. When the inability of the robot vacuum cleaner to pass the obstacle on the one side is calculated, a power module is driven so that the robot vacuum cleaner avoids the obstacle. Therefore, the robot vacuum cleaner can be prevented from going on an obstacle such as a carpet. In addition, the robot vacuum cleaner can be prevented from passing an obstacle such as a door sill so as not to leave a cleaning area.

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.

Devices for moving on substantially vertical surfaces, tools for cleaning substantially vertical surfaces and systems for cleaning substantially vertical surfaces are disclosed.
