摘要： 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, which avoids a large connected area being dividing into a plurality of small areas in a process of dividing room areas, thus reducing working efficiency of the robot in indoor working areas. It is possible to save operation resources of the robot framing the working area, avoid using software resources to process framing and separating of corner areas of these isolated rooms, and there is no need to ensure that contour boundary positions of the working area framed on an indoor ground are all walls, thereby improving efficiency of the robot navigation along an edge.

摘要： A mobile device (80) recharging method and the mobile device (80) are provided. The recharging method includes: retrieving a stored target location of a charging base (10); navigating to the target location; if a target is not discovered during the navigation and/or at the target location, performing a regional search to search for the target. Because the regional search for the charging base (10) is added to the recharging process of the mobile device (80), even if there is a deviation or displacement in the location of the charging base (10), the mobile device (80) can still automatically search and find the charging base (10) at a high probability, thereby increasing the mobile device (80) recharging success rate.

摘要： 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. In the technical solutions provided by the present disclosure, when the autonomous mobile robot encounters an obstacle and the machine body is jacked up or walks to a pit, the driving wheel assembly is subjected to an acting force applied by the obstacle crossing assembly, besides its own gravity, and under the combined action of these forces, the change amplitude of the positive pressure between the driving wheel and the traveling surface is less than or equal to the set threshold value, so that increase of a friction force between the driving wheel and the traveling surface and improvement of an obstacle crossing capability of the autonomous mobile robot are further facilitated.

摘要： The present invention relates to a cleaning robot and a control method. The cleaning robot may include: a body; a moving mechanism, configured to support the body and driving the cleaning robot to move; a power module, configured to provide a driving force for the cleaning robot to move and work; a mopping module, configured to be mounted on the body and perform predetermined mopping work, where a mop is capable of being mounted on the mopping module; and a control module, configured to be electrically connected to and control the power module, to implement automatic moving and automatic working of the cleaning robot; and further includes a liquid supply device, where the control module can control, based on a current mopping condition, the liquid supply device to convey a liquid to the mopping module. The beneficial effects of the present invention are that the cleaning robot can complete mopping work more efficiently, to reduce burden of a user and improve the degree of automation and the user experience of the cleaning robot. The cleaning robot can intelligently and autonomously control, based on the current mopping condition, the liquid supply device to convey a liquid to a mop, thereby prolonging the service life of a ground material such as a floor in home of the user.

摘要： Disclosed by the present invention is a sweeping robot, wherein the sweeping robot comprises: a base plate and a contact-type detection electrode; the contact-type detection electrode is mounted at a front portion of the base plate. When the contact-type detection electrode makes contact with dirt that may be dispersed, the resistance, capacitance or impedance of the contact-type detection electrode changes. The technical solution of the present invention is helpful in improving the detection accuracy of a sweeping robot.
