A breakpoint continuous mopping method and apparatus for a mopping robot, a medium, and an electronic device, are described. In the present disclosure, if the mopping robot working in a hybrid mode detects that a water tank for supplying water for mopping is short of water at a first breakpoint position, the mopping robot is switched to a mopping mode after the water tank is supplemented with water, and carries out supplementary mopping on an unmopped region including the first breakpoint position. Thus, it is guaranteed that the mopping robot can complete sweeping and mopping tasks.

An autonomous floor cleaning robot includes a transport drive and control system arranged for autonomous movement of the robot over a floor for performing cleaning operations. The robot chassis carries a first cleaning zone comprising cleaning elements arranged to suction loose particulates up from the cleaning surface and a second cleaning zone comprising cleaning elements arraigned to apply a cleaning fluid onto the surface and to thereafter collect the cleaning fluid up from the surface after it has been used to clean the surface. The robot chassis carries a supply of cleaning fluid and a waste container for storing waste materials collected up from the cleaning surface.

A moving robot is provided. The moving robot includes: a main body forming the exterior appearance; a moving means for moving the main body; a bumper configured to protrude on the outer perimeter of the main body; impact sensors placed at an angle on the main body to sense the movement of the bumper; and pressure parts formed in a bent shape at the end of the impact sensors.

A cleaner including a wet cloth brush to which a pad is installable so as to be below a bottom surface of the wet cloth brush, the wet cloth brush including a pad motor configured to rotate a pad installed to the wet cloth brush, a water supplier configured to spray water to a surface to be cleaned, a light source configured to irradiate light to the pad installed to the wet cloth brush, and a processor configured to, based on an intensity of the light reflected from the pad, control a rotation speed of the pad motor, and/or control an amount of water sprayed by the water supplier to the surface to be cleaned.

An escaping method of a cleaning robot includes: when the cleaning robot encounters an obstacle and turns around while performing cleaning along an edge of a first surface medium area, in response to a surface medium change signal from the surface medium sensor indicates that a second surface medium area is detected, searching an established room map to determine whether the second surface medium area exists in the room map; if the second surface medium area exists, determining whether a route bypassing the second surface medium area exists based on the room map and a boundary of the second surface medium area in the room map; if the route exists, controlling the cleaning robot to travel along the route to bypass the second surface medium area; and if the route does not exist, controlling the cleaning robot to return along a cleaned route to bypass the second surface medium area.

An electric robot includes a housing, an impeller, a suction motor, and a filtering structure. The housing is provided with a water inlet and a water outlet. The impeller is provided in the housing, and located between the water inlet and the water outlet. The suction motor is provided in the housing, and includes a motor main body and a motor shaft provided therein. The impeller is sleevedly provided on the motor shaft. The suction motor is configured to drive the impeller to rotate around an axis of the motor shaft through the motor shaft to generate suction. A rotational speed of the motor shaft is adjustable. The filtering structure is provided in the housing, and is located between the impeller and the water outlet.

A system and method of obstacle and cliff detection for an autonomous or a semi-autonomous cleaning device utilizing a calibration health monitor and occupancy grid filters. A calibration health monitor is used for monitoring and making minor adjustments to camera calibration over time. An occupancy grid filter is a 3D occupancy grid for probabilistically observing obstacles with 3d sensors that are susceptible to noise or other inaccuracies.

A robot cleaner may include a main body; a traveling assembly moving the main body; a cleaning tool assembly installed in the lower part of the main body, and contacting a floor to clean the floor; a water-feeding unit supplying water to the cleaning tool assembly; and a capacitance measurer contacting the cleaning tool assembly, and measuring capacitance of the cleaning tool assembly in order to calculate an amount of water of the cleaning tool assembly. Accordingly, by measuring an amount of water of a cleaning tool installed in a robot cleaner based on capacitance, it is possible to accurately measure an amount of water absorbed in a cleaning tool.

Disclosed is a robot cleaner including a body having a module location portion, a traveling module for moving the body, and a sliding module having a body location portion detachably coupled to the module location portion, the sliding module being configured to slide along a floor when the body is moved. A mop fixing unit for fixing a replaceable mop is provided between the module location portion and the body location portion.

A system for performing inventory management and cleaning within a commercial facility includes a mobile cleaning vehicle configured to clean a floor of the commercial facility. A computer is in communication with the cleaning vehicle, at least one imaging sensor, a transmitter, and a receiver. The computer is configured to capture inventory images from the at least one imaging sensor and detect inventory by comparing captured inventory images with stored inventory images. Inventory information is determined and a confidence level for the inventory information is determined. At least a portion of the inventory information having a confidence level above a threshold is communicated to the database. The cleaning vehicle may be a semi or fully autonomous cleaning vehicle having wheels and a floor cleaning system.
