Abstract: Embodiments of the present disclosure provide an autonomous mobile robot and a walking method thereof. The autonomous mobile robot includes a machine body, a driving wheel assembly and an obstacle crossing assembly. The driving wheel assembly is rotatably arranged on the machine body through a first rotating shaft. The driving wheel assembly includes a driving wheel. When the driving wheel moves from a first position to a second position relative to the machine body, the obstacle crossing assembly applies a force to the driving wheel assembly to make a change amplitude of positive pressure between the driving wheel and a traveling surface less than or equal to a set threshold value.

Abstract: A mother-child robot cooperative work system and a work method thereof include a mother robot and a charging base0, in which the mother robot is provided with a control unit and a work unit. The system also includes child robot, communicatively coupled to the mother robot. The mother robot performs cleaning for a work area under the control of the control unit, and recognizes cleanable area and assisted cleaning area in a cleaning process. After cleaning work in the cleanable area is completed, the control unit in the mother robot controls the child robot to cooperatively complete the cleaning work in the assisted cleaning area. The mother robot is provided with a child robot pose sensing unit. The unit inputs child robot pose information to the control unit; and the control unit controls the child robot to act as indicated.

Abstract: Provided are dynamic region division and region passage identification methods and a cleaning robot. The dynamic region division method includes: acquiring environment information collected by a robot when working in a first region; determining whether the robot has completed a work task in the first region, when a presence of a passage entering a second region is determined based on the environment information; and complementing a boundary at the passage to block the passage, when the work task is not completed. According to the technical solution provided by the embodiment of the present application, the occurrence probability of repeated sweeping and miss sweeping is reduced, and the cleaning efficiency is high. In addition, the technical solution provided by the embodiment of the present application relies on the environment information collected during the work, rather than relying on historical map data, so that the environmental adaptability is high.

Abstract: Provided are a structured light module and an autonomous mobile device. A structured light module comprises a camera module and line laser emitters distributed on two sides of the camera module; the line laser emitters emit line laser outwards; and the camera module collects an environmental image detected by the line laser. By virtue of the advantage of high detection accuracy of the line laser, front environmental information may be detected more accurately. In addition, the line laser emitters are located on two sides of the camera module. This mode occupies a small size, may save more space, and is beneficial to expand an application scenario of a line laser sensor.

Abstract: Embodiments of the present disclosure provide a robot, a robot system, a dust box, and a control method. The robot includes a body, provided with a suction port and a dust box, which are fluid communicated. The dust box is provided with a plurality of dust outlets and a dust inlet communicated with the suction port. All of the plurality of dust outlets are closed when the body is in a first mode, and dust on a surface is collected into the dust box through the suction port. The plurality of dust outlets work cooperatively to discharge the dust stored in the dust box under an action of a suction airflow when the body is in a second mode. The amount of dust residue in the dust box may be effectively reduced according to the technical solution provided by the embodiments of the present disclosure.
