Hadrian X bricklaying robot builds first homes in demo program

According to an analysis from Zillow, the U.S. is short 4.5 million homes. This has resulted in skyrocketing housing prices and an increase in unhoused populations. FBR Ltd., or Fastbrick Robotics, has designed, developed, built, and operated dynamically stabilized construction robots to close this gap.

In 2024, the Perth, Australia-based company completed the first five homes in a demonstration program with CRH Ventures using its Hadrian X system. This marked its first builds in the U.S., showing the system’s versatility and adaptability across various home styles and sizes.

The Hadrian X system is a mobile robotic blocklaying machine. It can work outdoors in uncontrolled environments to build block structures from a 3D CAD model. It can build the wall of a house on site in just a day.

The system does this using unique optimization software that converts wall sketches into block positions. At the same time, it minimizes handling and waste of block products to improve efficiency.

Hadrian X uses FBR’s Dynamic Stabilization Technology (DST) to precisely place blocks. DST corrects for dynamic interference and vibration in the boom and layhead in real time.

The system also includes the Fastbrick Wall System, a combination of Hadrian-optimized blocks and adhesive, together with a cladding material like acrylic render. Hadrian X uses modularly designed blocks with aligned cores, enabling easy installation of cabling and services through the cavities.

The system doesn’t just quickly build homes; it also creates safer working environments, said FBR. It also places blocks with greater accuracy, helps move toward zero-waste construction, and is less expensive than traditional building methods.
