An automatic floor-disinfection robot for floors of hospital rooms, including a moving device, a alarm and a disinfection device. The moving device is a disc-shaped robot, and includes a chassis moving mechanism, a support plate and a top plate arranged successively from bottom to top. The disinfection device includes a disinfection assembly and a baffle. The disinfection assembly includes a liquid supply mechanism, a liquid spray mechanism and a fan.

An autonomous mobile device and a control method are disclosed. The autonomous mobile device includes a main body and an imaging device, a detecting device, a light source assembly, and a controller disposed at the main body. The imaging device is configured to acquire image information in a predetermined direction of the main body. The predetermined direction includes an upward direction of the main body. The detecting device is configured to detect obstacle information in the upward direction of the main body. A light outputting direction of the light source assembly includes the upward direction of the main body. The controller is configured to, when the detecting device detects the obstacle within a predetermined distance range in the upward direction of the main body, control the light source assembly to turn on to provide illumination for the imaging device.

A vertical surface cleaning device comprising a main body, a cleaning arm, a cleaning head, and leg mechanisms with grippers. The cleaning head applies a cleaning fluid on a surface to carry out a cleaning operation. A waste collector is provided to collect a waste material arising from the cleaning operation. The grippers may remain in a grip or in a release state. The segments of the leg mechanisms are articulatable to configure a first group of the leg mechanisms to stably hold the main body at a first place with the grippers remaining in the grip state. A second group of the leg mechanisms move in a desired direction with their grippers in release state while the first group stably holds the main body. The first group of the leg mechanisms then moves in the same direction while the second group holds the main body at a second place.

Embodiments of the present disclosure disclose a mounting bracket and a self-propelled robot. The mounting bracket includes a housing, a rotating shaft and a magnetic positioning assembly. The housing is provided with an inner cavity. The rotating shaft is configured to rotate about an axis in the inner cavity. The magnetic positioning assembly includes a first magnetic element and a second magnetic element which are respectively arranged on the housing and the rotating shaft. The laser distance sensor is attached to the rotating shaft and configured to rotate about the axis. The mounting bracket is configured to prevent the rotating shaft from deviating from the axis by generating a force between the first magnetic element and the second magnetic element in a radial direction of the rotating shaft.

The present disclosure provides a method for expanding a working area based on a laser map, a chip and a robot, and the method for expanding the working area includes using map pixel point information obtained by laser scanning to position pending boundary lines, deciding a next expansion of a rectangular working area according to an increment of a diagonal length of the rectangular working area framed by the pending boundary lines in a current expansion process, stopping expanding the rectangular working area of the robot when the increment of the diagonal length before expanding and after expanding reaches an overlap condition.

The present disclosure relates to a blockage and a smart cleaning device. The blockage includes a plug body and a hierarchical sealing structure. The plug body is a shaft-shaped structure as a whole, and is provided with a through hole that penetrates the plug body. The hierarchical sealing structure is sleeved on an outer side of the plug body, and is provided with at least two annular plugs stacked in an axial direction of the plug body.

A cleaning robot, comprising: a robot body, a control unit provided in the robot body, and a fixing unit provided at the bottom of a front end of the robot body, the fixing unit comprising a sleeve and an ultrasonic sensor, the ultrasonic sensor being fixed in the sleeve and being electrically connected to the control unit, and the ultrasonic sensor being used for emitting an ultrasonic wave downwards and receiving an echo reflected by different ground forms.

The present disclosure provides a surface cleaning apparatus that includes task lighting. The task lighting can be provided on a hand-carried body or housing of the surface cleaning apparatus. Power to the task lighting can be controlled by a switch. The task lighting can be adjustable relative to the hand-carried body, and can be directed to illuminate a desired location.
