“…Origami actuators have shown significant utility in the microrobotics community, due to their precise motion control and amenability to 2D fabrication techniques ( 16 , 17 ). Origami patterns are modular ( 18 ), enabling units to be developed independently and combined to create more complicated functional structures. In addition, localization of deformation to the fold lines mechanically protects the facets, providing regions that can host electronic hardware.…”

SignificanceAutonomy separates robots from machines. Incorporating autonomy into soft robots is an outstanding challenge due to the mismatch between rigid electronics and the compliant bodies. In this work, we demonstrate origami as a platform for compliant mechanical logic, containing mechanical bits, logic gates, and signal transmission mechanisms that can supplement conventional electronic controls. Furthermore, these processes can be responsive to and programmed by the environment via the integration of adaptive materials. Thus, origami provides a framework in which sensing, computation, and reflexes can be seamlessly integrated into the compliant bodies of soft robotics.

“…The ability of linkage-based origami to tessellate in two dimensions is an important characteristic that will influence its suitability for engineering applications such as large deployables. Such a tessellation is possible using developable vertices 27 , 38 , 39 , but complicated geometry is required to prevent self-intersection in the folded state for thick models. Tessellation is also possible using the thick, Eggbox tessellation shown in Fig.…”

Origami concepts show promise for creating complex deployable systems. However, translating origami to thick (non-paper) materials introduces challenges, including that thick panels do not flex to facilitate folding and the chances for self-intersection of components increase. This work introduces methods for creating permutations of linkage-based, origami-inspired mechanisms that retain desired kinematics but avoid self-intersection and enable their connection into deployable networks. Methods for reconfiguring overconstrained linkages and implementing them as modified origami-inspired mechanisms are proved and demonstrated for multiple linkage examples. Equations are derived describing the folding behavior of these implementations. An approach for designing networks of linkage-based origami vertices is demonstrated and applications for tessellations are described. The results offer the opportunity to exploit origami principles to create deployable systems not previously feasible.

“…The search for material minimalization visible in Nature becomes an essential structural and architectural optimisation aspect in the XXI century (Dixit, Stefańska and Musiuk, 2020). Structural transformations based on natural patterns such as folding systems (Patil and Vaijapurkar, 2007;Mousanezhad, Kamrava and Vaziri, 2017;Kresling, 2012) remain an amusing aspect of designing both in architectural aesthetic and structural logic. The case study results indicate that structural efficiency becomes more efficient while organising the structural curvature at first.…”

Digital fabrication leads architects and structural engineers to modify the design optimisation methodology. The designers, as never before, are facing new technologies developed in the search for new materials based, among others, on wood components and the improvement of manufacturing methods at the same time. In this process, the material and manufacturing technology adjustment to desired aesthetic outcomes is possible not only by the material used but also by the self-organisation of the structure's optimisation. New fabrication techniques linked with topology optimising software change traditional load-bearing systems designing using timber and wood-based materials. Multi-objective optimisation research indicates that timber might be a comprehensive material based on various applications from low-tech to cutting-edge contemporary fabrication technologies. The article presents new tools and methods for the optimisation of structural elements. A case study based on interdisciplinary architectural and structural optimisation suggests the possible effective research-based design. Comparing contemporary buildings with wood load-bearing structures explains timber usage's diversity and characteristics in modern design.
