    “Atrium is the operating system behind everything we do. Our proprietary software takes architectural drawings and turns them into robot-executable plans, coordinates a fleet of robots on each site, localizes robots with millimeter accuracy, tracks every brick, and QAs the wall as it gets built”

    “Pisa is the main robot in our fleet and our automated mason. It builds brick walls autonomously by combining bricklaying and mortar application in a single coordinated process. Pisa is equipped with two cranes: Gripper, which picks up and places bricks with millimeter precision, and Hopper, which applies mortar evenly between each course.”
