Not building, but printing a house in the realities of 2017 is already easy. However, people are not yet ready to entrust robots with the construction of even temporary structures, not to mention capital ones. Machines are diligent, but stupid and do not know how to control dozens of factors on which the reliability of a structure depends. The Cogiro system should be the first to do it.
It was originally designed as a warehouse controller that moves in three planes and measures, examines the location of pallets and load cells for optimal placement. The Cogiro looks like a large frame 15 × 11 × 6 m, inside which the working head moves along a system of pulleys and cables. In principle, anything can be mounted on it - in the next experiment it became the nozzle of a construction 3D printer.
Using a plastic melt similar to cement slurry, the robot can pour the foundation, fill the building frame, print any necessary structures inside it. It moves very accurately, despite the fact that it has to work on a large area, but the main pride of Catalan engineers is the self-control of Cogiro. Using temperature sensors, the robot determines the degree of dryness of the already printed layers and avoids placing new ones on a still damp base.
He himself studies and realizes a drawing from a CAD file, he builds walls himself, and he himself controls the quality of work. Cogiro already serves as an entire construction team, and when trained to work with cheap and common cement and concrete instead of plastic, he can create real buildings. From flimsy canopies to high-strength hangars for space technology and workshops for nuclear power plants.
