Patent attributes
A robotic system having a movable gantry robot (10) for conducting construction operations. The gantry may have an expandable bridge (20) and articulated gantry support legs (34) as well as a support track system (60) holding a gantry robot (800) which may hold one or more implements and peripheral devices (806). The device can be moved by propulsion mechanisms, a controller, and one or more geo-positioned control devices to provide position information for the robotic gantry as it moves back and forth along a plurality of work sites (700). The robotic gantry is connected to a power supply system (236). The controller is automated, self-navigating, and activates, deactivates, and/or changes the operation of the propulsion mechanisms, and deploys, retracts, activates, deactivates, and/or changes the operation of one or more of the construction implements. The height of the frame may be adjusted by extending and rotating risers and booms to accommodate different building heights or sub-level heights at a worksite. A conveyor system is optimized for removing dirt from or delivering material to the robotic arm. This invention can be applied to automating construction jobs including surveying, land preparation, excavation, foundation, masonry, framing, and additive fabrication.
