The sweeping structure is located in a front of the automatic mopping and cleaning mechanism. The automatic mopping and cleaning mechanism includes an automatic cleaning structure for mopping rollers, a plurality of wet mopping rollers, a plurality of dry mopping rollers for mopping a floor and being cleaned respectively in turn, and a spray nozzle spraying water on one of the wet mopping rollers mopping the floor and further spring water on a region of the floor in a front of the one of the wet mopping rollers. The one of the wet mopping rollers mopping the floor is located in a front of one of the dry mopping rollers mopping the floor.

Abstract: A method for constructing a real-geographic-space scene in real time based on a panoramic-video technique is provided. By using a measuring robot and the attitude sensors, accurately determining the geographic coordinates and the attitudes of the cameras, where the cameras may be installed in a fixed or stringing manner, where in the fixing type a plurality of neighboring videos at the same moment undergo orthographic correction and splicing, and in the stringing type the cameras are installed to a guiding device and may locally, independently and quickly move and shoot, and the videos of the neighboring cameras are spliced in real time; and fusing the videos, the geographic coordinates and the environment sounds that satisfy the delay time, to form a scene video streaming.

Abstract: mechanical arm type measuring robot device and an application method, and relates to the technical field of intelligent coal mine mining. The mechanical arm type measuring robot device comprises an automatic leveling total station, a protection mechanism, a pitch adjusting mechanism, a yaw adjusting mechanism, a vertical rotating mechanism, a controller, a mounting base and a mobile terminal. Based on a preset pitch angle and a preset yaw angle, the measuring robot starts from an initial position, and performs extension and retraction actions in a plurality of degrees of freedom in the pitch adjusting mechanism and the yaw adjusting mechanism to move the total station to a preset working position.
