Robot 3D prints a building
Researchers at the Massachusetts Institute of Technology, USA, have designed and built a system that can 3D print an entire building. The system includes a tracked vehicle with a large, industrial robotic arm, which has a smaller, precision-motion robotic arm at its end. The controllable arm is able to pour concrete and spray insulation material and additional digital fabrication end effectors.
Proving concept, the robot recently constructed a 12-foot-high dome in less than 14 hours. The researchers say that it will be able to operate independently, and be able to use an array of materials to construct complex structures.
