VIDEO: Three Robots Built This 3D-Printed Hut
Researchers at the Institute for Advanced Architecture of Catalonia in Spain, have created an ingenious three-step process, called Minibuilders, for 3D-printing a simple home that looks less like the product of construction, and more like something that grew straight out of nature. In a six-month-long project led by robotics researcher and inventor Sasa Jokic, the IAAC employed three robots. The "Foundation" robot, the first and largest robot, uses a line sensor to follow a preset pattern on the ground to trace out, and build up, the home’s foundation.
