The patent describes a lightweight robotic gantry system using cables for stiffness and rigidity to enable precise movement of a fluid delivery nozzle in 3D space for contour crafting construction. It addresses limitations of heavy traditional gantries by employing light structural members reinforced with tensioned cables.

Claims

A robotic gantry system comprising two columns riding on rails, a bridge connecting the columns, and cables providing resistance against bending and rotation, configured for moving a fluid delivery nozzle in X, Y, and Z directions for automated construction.

Technical analysis

The system uses a cable-tensioned lightweight frame (columns, bridge) to achieve high stiffness with minimal mass, enabling large-scale 3D printing-like construction via contour crafting. Key innovations include cable routing for multi-axis stability and integration with material transport hoses.

Commercial impact

Enables scalable, automated construction of buildings with reduced labor, material waste, and time; relevant to 3D printing in construction industry and large-scale robotics deployment.
