Overview
- Crest Robotics and Earthbuilt Technology showcased the Charlotte prototype at the 76th International Astronautical Congress in Sydney.
- Developers claim the mobile robot could 3D‑print a 200‑square‑meter home in under 24 hours using on‑site materials such as sand, earth, or rubble.
- The machine uses a proprietary extrusion and binder process, features a lightweight foldable design, and is pitched as transportable for remote or lunar sites.
- The project has backing from New South Wales’ Space+ program implemented by the SmartSat consortium, with teams seeking additional partners and funding.
- Charlotte remains an early demonstrator with unvalidated performance, and developers cite outstanding hurdles including materials testing, autonomy, energy supply, building codes, and lunar environment challenges.
