“…[171] Some of these principles can be mimicked with rigid motors and joints,but the introduction of soft materials offers designs with greater similarity to the flying animals. [172] By incorporating ap assive flexible membrane and active muscle-like components,s uch as shape-memory alloys or motor-driven elastic tendons,b at-mimicking robots have demonstrated sophisticated morphing schemes based on both passive and active mechanisms. [168,173] Whereas bats store the elastic energy in muscles on their wings,insects have completely passive wings made of thin membranes,a nd the elastic energy is stored and released through muscles attached at the wing base,t ot he thorax, or both.…”

Soft materials possess several distinctive characteristics, such as controllable deformation, infinite degrees of freedom, and self‐assembly, which make them promising candidates for building soft machines, robots, and haptic interfaces. In this Review, we give an overview of recent advances in these areas, with an emphasis on two specific topics: bio‐inspired design and additive manufacturing. Biology is an abundant source of inspiration for functional materials and systems that mimic the function or mechanism of biological tissues, agents, and behaviors. Additive manufacturing has enabled the fabrication of materials and structures prevalent in biology, thereby leading to more‐capable soft robots and machines. We believe that bio‐inspired design and additive manufacturing have been, and will continue to be, important tools for the design of soft robots.

“…Vögel ändern ihre Flügelform über die aktive Bewegung der Gelenke, Fledermäuse spannen wirksam die Flügelfläche durch die Steuerung der im Flügel eingebetteten Muskelfasern, und Insekten haben Membranflügel mit intrinsischer Flexibilität, die sich der aerodynamischen Strömung passiv anpassen . Einige dieser Prinzipien können zwar mit starren Motoren und Gelenken nachgeahmt werden, jedoch liefert die Einführung weicher Materialien Designs mit größerer Ähnlichkeit zu fliegenden Tieren . Durch Integration passiver flexibler Membrankomponenten und aktiver muskelähnlicher Komponenten, wie Formgedächtnislegierungen oder von einem Motor angetriebene elastische Spannglieder, verfügen Fledermäuse imitierende Roboter über ein ausgeklügeltes Verformungssystem, das sowohl auf passiven als auch auf aktiven Mechanismen beruht .…”

Weiche Materialien weisen einige Besonderheiten auf, wie steuerbare Verformung, unendlichen Freiheitsgrad und Selbstorganisation, die sie zu vielversprechenden Kandidaten für die Entwicklung von weichen Maschinen, Robotern und haptischen Schnittstellen machen. In diesem Aufsatz geben wir einen Überblick über die aktuellen Fortschritte auf diesen Gebieten, wobei der Schwerpunkt auf zwei speziellen Themenfeldern liegt: bioinspiriertem Design und additiver Fertigung. Die Biologie ist eine ergiebige Quelle der Inspiration, die bei vielen funktionellen Materialien und Systemen genutzt wird, um die Funktion oder den Mechanismus biologischer Gewebe, biologischer Wirkstoffe und des biologischen Verhaltens nachzuahmen. Die additive Fertigung ermöglichte die Herstellung von Materialien und Strukturen, die in der Biologie weit verbreitet sind. Wir sind der Überzeugung, dass bioinspiriertes Design und additive Fertigung wichtige Instrumente für die Entwicklung von weichen Robotern sind und bleiben werden.

“…Many existing aerial vehicles do employ some kind of morphing wing [82,83], and others feature deployable wings [3,84]. However, wing deployment systems are often merely for storage, without the ability to refold, and most morphing concepts only vary the wing geometry slightly.…”

Abstract.Current Micro Aerial Vehicles (MAVs) are greatly limited by being able to operate in air only. Designing multimodal MAVs that can y eectively, dive into the water and retake ight would enable applications of distributed water quality monitoring, search and rescue operations and underwater exploration. While some can land on water, no technologies are available that allow them to both dive and y, due to dramatic design trade-os that have to be solved for movement in both air and water and due to the absence of high-power propulsion systems that would allow a transition from underwater to air. In nature, several animals have evolved design solutions that enable them to successfully transition between water and air, and move in both media. Examples include ying fsh, ying squid, diving birds and diving insects. In this paper, we review the biological literature on these multimodal animals and abstract their underlying design principles in the perspective of building a robotic equivalent, the Aquatic Micro Air Vehicle (AquaMAV). Building on the inspire-abstract-implement bioinspired design paradigm, we identify key adaptations from nature and designs from robotics. Based on this evaluation we propose key design principles for the design of successful aerial-aquatic robots, i.e. using a plunge diving strategy for water entry, folding wings for diving eciency, water jet propulsion for water take-o and hydrophobic surfaces for water shedding and dry ight. Further, we demonstrate the feasibility of the water jet propulsion by building a proof of concept water jet propulsion mechanism with a mass of 2.6grams that can propel itself up to 4.8m high, corresponding to 72times its size. This propulsion mechanism can be used for AquaMAV but also for other robotic applications where high power density is of use, such as for jumping and swimming robots.
