Monumental

Corporate marketconstructionCurated record

Three-robot collaborative system operating via the Atrium AI software platform: two autonomous supply carts transport bricks and mortar to the main bricklaying robot, which uses computer vision and a crane-like arm to place red clay bricks at approximately 500 bricks per 8-hour shift. SLAM-based navigation for rough outdoor terrain; fully electric; compact enough to fit through standard door openings and navigate tight construction sites. Software-defined wall geometry from architectural plans; supports complex brick patterns and multi-colour configurations.
