Bistable soft jumper capable of fast response and high take-off velocity

In contrast to jumping robots made from rigid materials, soft jumpers composed of compliant and elastically deformable materials exhibit superior impact resistance and mechanically robust functionality. However, recent efforts to create stimuli-responsive jumpers from soft materials are limited in their response speed, take-off velocity, and travel distance. Here, we report a magnetic-driven, ultrafast bistable soft jumper that exhibits the highest jumping capability (jumping over 108 body heights with a take-off velocity of over 2 m/s) and the fastest response time (less than 15 ms) compared to previous soft jumping robots. The snap-through transitions between bistable states form a repeatable loop that harnesses the ultrafast release of stored elastic energy. Based on the dynamic analysis, the multimodal locomotion of the bistable soft jumper can be realized: the interwell mode of jumping and the intrawell mode of hopping. These modes are controlled by adjusting the duration and stren..., , , # Data from: Bistable soft jumper capable of fast response and high take-off velocity

与刚性材料制备的跳跃机器人相比，由柔顺弹性变形材料构成的软体跳跃装置，展现出更优异的抗冲击性能与机械稳健的功能特性。然而，当前基于软体材料开发刺激响应型（stimuli-responsive）跳跃装置的研究，在响应速度、起跳速度与跳跃距离方面仍存在局限。

本研究报道了一款磁驱动超快速双稳态（bistable）软体跳跃装置：相较于现有软体跳跃机器人，其跳跃性能（可跃过108倍自身高度，起跳速度超过2 m/s）与响应速度（小于15 ms）均达到最优水平。双稳态间的突跳转变形成可重复的能量循环，实现了存储弹性势能的超快速释放。基于动力学分析，该双稳态软体跳跃装置可实现多模态运动：势阱间跳跃模式与势阱内弹跳模式，可通过调整作用时长与强度……
