The machine is being developed by Australian startup Crest Robotics in collaboration with Earthbuilt Technology, which has developed an eco-friendly material made from a mixture of sand, glass, and brick fragments. Buildings made from this material are strong, moisture- and fire-resistant, and the use of local components will help reduce the carbon footprint.

Instead of performing a multitude of separate operations, the robot uses an extrusion system to “print” building elements from this material layer by layer. Its design resembles spider legs, allowing the device to move independently and even climb as the structure grows. This makes the construction process continuous and allows a single machine to complete the entire process from start to finish.

The project is still being refined, but a scaled-down prototype has already been shown at exhibitions. In the future, Charlotte is planned to be used not only for rapid house construction, but also for building research bases on the Moon
