Abstract: A method of constructing an indoor wall corner two-dimensional semantic map based on a robot platform includes controlling, by the master control computer, the robot platform to move indoors, collecting, by the lidar sensor, a distance between an indoor object and the robot platform and a direction angle between the indoor object and the robot platform in real time and transmitting the distance and the direction angle to the master control computer, and obtaining, by the master control computer, an environment grid map and a real-time pose of the robot platform by processing the distance between the indoor object and the robot platform and the direction angle between the indoor object and the robot platform based on Gmapping algorithm; constructing a semantic segmentation data set as a training set on the master control computer and obtaining a predicted non-wall corner semantic label.

Abstract: The present invention is a kind of bulk lifting transportation system applied in buildings, which relates to the elevator technology field and the construction field. It includes a lift shaft, and the lift shaft is provided with a driving mechanism, a reversing mechanism, and its transportation belt. The driving mechanism and the reversing mechanism are respectively arranged at the two ends of the lift shaft, and the conveyor belt bypasses the reversing mechanism and is connected with the driving mechanism; The conveyor belt is provided with loading devices for placing stuff at intervals. The number of loading devices is the same as the number of floors of the building, and the distance between adjacent loading devices is equal to the distance between adjacent pick-up openings; The process of connecting and separating greatly saves the time required for single lifting transportation and can significantly improve transportation efficiency.

Abstract: A plane storage and transportation unit of a stereoscopic warehouse with four-direction movable goods allocations, wherein: groups of tracks are disposed on the X and Y axes vertical to the rectangular coordinate system; a goods carrier or a device for moving it is run on tracks and moves by power systems; at each intersection of tracks, the track and advancing system of the goods carrier or the device for moving it enable an advancing direction of the goods carrier to be transformed between the tracks; or a unit power roller conveyor or power conveyor belt tightly provided with rotation direction transfers and moves goods. It is used on the basic plane component of storage and transportation of stereoscopic warehouse or parking garage; library collections, archives archiving, museum collections, and storage of goods; built-in cabinet with partition wall in smart home; museum collections, artworks, jewelry, clothing and other display systems.

Abstract: A module splicing structure comprises to-be-spliced modules (C), a connecting component (A), a reinforcing accessory (B), and functional accessories (D, E, G). The to-be-spliced modules (C) are provided with holes or troughs. The connecting component (A) is inserted into the holes or the troughs of two adjacent to-be-spliced modules (C). The shape of the whole or partial cross section of the connecting component (A) inserted into the to-be-spliced modules (C) is the same as the shape of the cross sections of the holes or the troughs of the to-be-spliced modules (C). Connected by the connecting component (A), multiple to-be-spliced modules (C) are spliced into a whole structure or a building. The structure is applied to the field of engineering construction, and can be assembled, disassembled and maintained conveniently and quickly.
