The article is here.Engineer Behrokh Khoshnevis, at the University of Southern California, has been perfecting his "contour crafter" for more than a year. "The goal is to be able to completely construct a one-story, 2000-square foot home on site, in one day and without using human hands," he says.
Now Degussa AG, of Dýsseldorf, Germany, the world's largest manufacturer and supplier of building materials, is to collaborate on the project to help Khoshnevis find the best kind of building material.
I am fascinated and skeptical at the same time about a robot building a home. That sounds like the start of something. I can see in the future how insulation could be squirted in with different nozzles. One day to build a shell for a home is mind boggling. I would like to see some the examples of the architecture that would be possible, as the article says, with this technology.
