Secondary veins are designed using the WCV algorithm. (g, h) Flapping drone equipped with coupling wings. The two wings are locked in flight position and behave as one while flapping. When the forewing pivots to the flight position, its coupling (yellow) on the trailing edge hooks the hindwing's coupling (green), and they deploy together. Forewing and hindwings overlap and can be stored compactly. (f) Schematic of the coupling wing model. (e) Microscopic image of the cross-section of the connected coupling structures. (c, d) Coupling structures on a forewing and hindwing, and schematics of their cross sections. The coupling structures are disconnected, and the forewings are overlapped on the hindwings for compact storing after landing on a tree. The trailing edge of the forewing and the leading edge of the hindwing have coupling structures with hook-shaped cross sections, which connect the two wings during flight. Cicadas use two pairs of wings (forewings and hindwings) for flight. (a, b) Wings of a cicada (Diceroprocta apache (Davis, 1921)). In coupling-type wings, the forewing and hindwing are connected to form a single large wing during flight these wings can be stored compactly by disconnecting and stacking them like cicada wings.ĭesign of coupling wing. The proposed crease pattern design software developed based on a beetle hindwing enables the 3D printing of foldable wings of any shape. Furthermore, we implemented two representative functions found in actual insect wings: folding and coupling. The artificial venation generation algorithm based on the centroidal Voronoi diagram, which can be observed in the wings of dragonflies, was used to design the complex mechanical properties of artificial wings. This study presents a simple integral forming method for an insect-wing-type composite structure by 3D printing wing frames directly onto thin films. Consequently, the essence of their excellent environmental adaptability and locomotive ability should be clarified a simple and versatile method to artificially reproduce the complex structure and various functions of these innumerable types of wings is necessary. Insects have acquired various types of wings over their course of evolution and have become the most successful terrestrial animals.
