Abstract: A metrology three-dimensional (3D) scanning system includes a metrology 3D scanning application (app) comprising computing instructions that, when executed by one or more processors, causing the one or more processors to: record human-robot interaction (HRI) data as a human operator operates the HRI device; generate a preliminary scan path based on the HRI data for operating a robotic element within an operating environment; move the robotic element along at least a portion of the preliminary scan path and record preliminary scan data comprising at least a subset of dimension data defining at least a target object; generate a metrology scanning path plan and a motion plan for the robotic element based on the preliminary scan data; and execute instructions to move the robotic element within the operating environment according to the metrology scanning path plan and the motion plan for scanning the target object.

Abstract: A composite core with non-traditional geometries includes multiple elongate tubes arranged in a two-dimensional array. Each tube is made of a composite material. Each tube includes multiple curved sides. Each curved side inwardly curves toward a longitudinal axis passing through a geometric center of the tube to form a valley on an outer surface of the tube. An end of a first curved side connects to an end of a second curved side to form a crest on the outer surface of the tube. At least one crest formed on an outer surface of a first tube in the two-dimensional array contacts at least one valley formed on an outer surface of an adjacent second tube in the two-dimensional array.

Abstract: In the present disclosure, a method may include forming a three-dimensional composite fiber pre-form by three-dimensionally weaving a plurality of composite fibers. The composite fiber pre-form includes a plurality of open cells formed adjacent to and interlocked with each other, and a composite fiber forms at least a portion of a first side of a first open cell and at least a portion of a second side of a second open cell. The first open cell and the second open cell are adjacent to and interlocked with each other.
