Spider-like robot can 3D print homes in a day to fight housing crunch

Australia has developed an advanced spider-like robot named Charlotte, designed to address the housing crisis by 3D printing low-cost, low-carbon homes rapidly. Created through a collaboration between Crest Robotics and Earthbuilt Technology, Charlotte can autonomously print a 200-square-metre house within 24 hours by transforming readily available materials such as sand, earth, and crushed brick into structural walls. The robot employs a sustainable Earthbagging-like technique, compacting these materials in fabric layers to build durable structures efficiently, offering a scalable solution to the slow and costly traditional construction methods. Beyond Earth, Charlotte is engineered for lunar construction, supporting NASA and other space agencies' ambitions to establish permanent bases on the Moon. Its lightweight, foldable hexapod design makes it highly portable for space travel, unlike bulky traditional 3D printers, and allows it to extrude and compact lunar soil to build habitats such as domed shelters. This innovation positions Charlotte within a competitive global effort alongside companies like ICON and AI SpaceFactory
