This technology, called Contour Crafting, can build a 232 square meter (2,500-square-foot) home in 20 hours. As you can see in the video, on a cleared and leveled site, workers would have to lay down two rails a few feet further apart than the eventual building’s width and a computer-controlled contour crafter takes over from there.
“A gantry-type crane with a hanging nozzle and a components-placing arm would travel along the rails,” Brad Lemley from Discover Magazine said. “The nozzle would spit out concrete in layers to create hollow walls, and then fill in the walls with additional concrete… humans would hang doors and insert windows.”
The technology would be ideal for slums and areas destroyed by natural disasters, as the robot’s construction is cheaper, stronger, faster, safer and more eco-friendly than manual construction. And if this wasn’t enough, check this out: it can also tile the floors, install plumbing, install electrical wiring and even paint or apply wallpaper.
