Engineers are developing the worlds first robots capable of building a complete house.

One method, inspired by the inkjet printer, involves computer-controlled robotic nozzles which pipe quick-drying liquid gypsum and concrete to form walls, floors and roofs, building the shell of the house in 24 hours.

“This is a harbinger of how we will eventually build large objects (like buildings) from modules constructed by nanoassemblers,” comments Ray Kurzweil.
