Planning the reconfiguration of grounded truss structures with truss climbing robots that carry truss elements Citation

In this paper we describe an optimal reconfiguration planning algorithm that morphs a grounded truss structure of known geometry into a new geometry. The plan consists of a sequence of paths to move truss elements to their new locations that generate the new truss geometry. The trusses are grounded and remain connected at all time. Intuitively, the algorithm grows gradually the new truss struct...

Hybrid carbon fiber composite lattice truss structures

Lattice truss structures from expanded metal sheet

Metallic lattice truss structures are usually made by perforating a metal sheet with a periodic diamond pattern followed by folding at node rows to create a plate of 3D interconnected trusses. For low relative density lattices, the initial sheet material is inefficiently utilized, and the node area is small raising concerns about node bond robustness under shear or tensile loading. Here, we exp...
