折纸可以实现紧凑且轻量的结构。然而，传统设计中的折纸结构的面本质上是不可变形的刚性板。因此，在这些结构中实现能量存储和强大的自锁可能具有挑战性。我们注意到，瓢虫复杂折叠的翅膀可以在飞行过程中快速展开并有效维持空气动力；这些能力源于这种昆虫翅膀上特殊静脉的几何形状和变形。我们报告了受瓢虫翅脉启发的顺应折纸。柔顺面的变形和几何形状可以在单个折纸关节中实现大量能量存储和自锁。在我们的合规折纸的基础上，我们开发了一种用于多模式机器人的可部署滑翔机模块。滑翔机模块紧凑可折叠，可快速展开，并能有效承受空气动力。我们还应用顺应性折纸来增强跳跃机器人跳跃机构的能量存储能力。
Origami can enable structures that are compact and lightweight. The facets of an origami structure in traditional designs, however, are essentially nondeformable rigid plates. Therefore, implementing energy storage and robust self-locking in these structures can be challenging. We note that the intricately folded wings of a ladybird beetle can be deployed rapidly and effectively sustain aerodynamic forces during flight; these abilities originate from the geometry and deformation of a specialized vein in the wing of this insect. We report compliant origami inspired by the wing vein in ladybird beetles. The deformation and geometry of the compliant facet enables both large energy storage and self-locking in a single origami joint. On the basis of our compliant origami, we developed a deployable glider module for a multimodal robot. The glider module is compactly foldable, is rapidly deployable, and can effectively sustain aerodynamic forces. We also apply our compliant origami to enhance the energy storage capacity of the jumping mechanism in a jumping robot.
