Building Online says that USC's Research Computing Facility plans to build an entire house by a fully automated robotic device by the Fall of 2005. The device is like a cross between a giant gantry shipping port crane and a cake decorating squeeze bag. The nozzel can ooze out walls of concrete complete with plumbing and electrical and trowel them smooth all controlled by a computer program. On their Contour Crafting website you can find animations and news vidoe clips of their device in action. They even plan to build structures on other planets! We've reported on the Robot Home Builders before.
