A few days ago, researchers from the United States demonstrated a prototype of a spider-like robot that was equipped with 3D printing technology that could work together to build complex structures and surfaces. This significant system, called SiSpis, was developed by a team of Siemens Corporate Technology in the Princeton University campus. This is the latest development of the company in the development of autonomous mobile manufacturing technology. Siemens believes that this technology will ultimately play a major role in the manufacture of all objects, from airplanes to ships. “We are considering the use of multiple autonomous robots to create some large structures, such as the body, hull and aircraft fuselage,†said Livio Dalloro, head of the SiSpis system development team. It is understood that the design and construction of the system is almost entirely done by Siemens itself. The software is based on the modified version of Siemens NX PLM software. Each spider robot is equipped with an extruder, which is equipped with traditional 3D. The extruder on the printer is similar. The printing material they use is PLA. In addition, each robot has a built-in camera and laser scanner that allows it to interpret the current environment. Under the premise that its 3D printing arm range is known, it will delineate its current working area, and other robots will use the same technology to cover the adjacent area. Thanks to algorithms developed by scientists for multi-robot task planning, two or more spider robots can perform collaborative 3D printing or surface processing for the same object or region. By dividing each area into a number of square boxes, machine people can work together and even complete complex geometries in this way. Interestingly, because these spider robots can sense the surrounding environment and know their location, when a certain machine's battery power drops to the warning line, it can return to the charging station autonomously to charge.
A bookcase, or bookshelf, is a piece of furniture with horizontal shelves, often in a cabinet, used to store books or other printed materials. Bookcases are used in private homes, public and university libraries, offices and bookstores. Bookcases range from small, low models the height of a table to high models reaching up to ceiling height. Shelves may be fixed or adjustable to different positions in the case. In rooms entirely devoted to the storage of books, such as libraries, they may be permanently fixed to the walls and/or floor.
A bookcase may be fitted with glass doors that can be closed to protect the books from dust or moisture. Bookcase doors are almost always glazed with glass, so as to allow the spines of the books to be read. Especially valuable rare books may be kept in locked cases with wooden or glazed doors. A small bookshelf may also stand on some other piece of furniture such as a desk or chest. Larger books are more likely to be kept in horizontal piles and very large books flat on wide shelves or on coffee tables.
