Abstract: Embodiments of the present disclosure relates to a warehousing system. The warehousing system includes a first ground marking arranged on a ground surface of a warehouse. The first ground marking includes machine-readable characteristics representing a warehouse location identification number (ID). The machine-readable characteristics include one or more horizontal lines parallelly arranged at equal intervals, wherein the total number of the one or more horizontal lines corresponding to a first information of the warehouse location ID, and one or more vertical lines parallelly arranged at equal intervals, wherein the total number of the vertical lines corresponding to a second information of the warehouse location ID that is different from the first information. The machine-readable characteristics are recognizable by one or more cameras of a self-driving system, and the self-driving system is operable to determine its position on a map of the warehouse based on the warehouse location ID.

Abstract: Disclosed are a method for locating a warehousing robot, a method for constructing a map, a robot and a storage medium. In a specific embodiment, a semantic map of a warehouse environment is constructed in advance, and the semantic map comprises a plurality of objects existing in the warehouse environment and semantic information of the objects. In the localization process, a warehousing robot uses its own image sensor to acquire an image or video data of a surrounding environment (11), identifies target objects in the image or video data and semantic information of the target objects (12) to obtain the relative position relationship between each target object and the warehousing robot (13), and then determines the location of the warehousing robot in the semantic map based on the relative position relationship and the semantic information of each target object (14). The method for constructing a map is based on visual semantic localization.

Abstract: An autonomous mobile robot checking system comprises a transmission line, an unmanned aerial vehicle and an autonomous mobile device. The unmanned aerial vehicle is used for sensing stacked goods to generate sensing information. The autonomous mobile device is used for receiving the sensing information through the transmission line, and supplying power to the unmanned aerial vehicle through the transmission line to enable the unmanned aerial vehicle to sense the stacked goods. The autonomous mobile device provides a checking result for the stacked goods based on the sensing information.
