SUMMARY:Computational Design of a Kit of Parts for Bending Active Structur
 es
DESCRIPTION:Quentin Becker, Uday Kusupati, Seiichi Suzuki, and Mark Pauly 
 (EPFL)\n\nBending-active structures are composed of elastic elements that 
 deform to achieve a desired target shape. To support effective design, inv
 erse algorithms have been proposed that optimize the geometry of each elem
 ent specifically for each design. This makes it difficult to reuse element
 s across designs or gain efficiency in fabrication through mass production
 .\n\nWe address this issue and propose a computational framework to ration
 alize bending-active structures into a sparse kit of parts. Our method sol
 ves for the optimal part geometry such that multiple input designs can be 
 faithfully realized with the same kit of parts. Assigning parts to differe
 nt assemblies leads to a combinatorial explosion that makes exhaustive sea
 rch intractable. Instead, we propose a relaxed continuous optimization inc
 orporating a physics-based simulation in its inner loop to model the elast
 ic deformation of the bending-active structure accurately. Our algorithm a
 llows analyzing different design trade-offs of a kit of parts to tune the 
 balance between fabrication complexity and fidelity to the original design
 s. We demonstrate our method on three different classes of bending-active 
 structures, showcasing the effectiveness of our approach for part reuse an
 d sustainable practices in fabrication-driven design.\n\nRegistration Cate
