A spider-shaped construction robot named Charlotte is being developed in Sydney to 3D print a full-size house in roughly a day. Developers say the machine can autonomously form structural walls for about a 2,150-square-foot home using locally sourced materials.
Instead of cement and bricks delivered by truck, Charlotte compacts sand, soil, and clean waste into layered walls on-site. Researchers argue that this single-machine approach removes long supply chains and many high-carbon steps.
Charlotte, the construction robot – Charlotte is a mobile, legged system that pairs robotics with additive manufacturing, building objects layer by layer with a printer.
