(Phys.org) — Researchers from the Institute for Advanced Architecture of Catalonia have built a programmable robot arm with a nozzle for a hand that allows for building structures out of sand mixed with water and binding agents, using a 3D printing technique. The result, called the Stone Spray Robot, was built by architects Inder Shergill, Anna Kulik and Petr Novikov, and is a part of the Stone Spray Project, whose purpose is to illustrate the concept of making habitual structures from earth friendly materials.
