▲摘要:
在此,我们展示了犀金龟可以毫不费力地展开它们的后翅,而不需要肌肉活动。我们展示了打开鞘翅会将像弹簧一样的后翅部分从身体上释放出来,从而为随后的拍打动作提供所需的空间,从而使后翅进入飞行位置。
飞行结束后,犀金龟可以利用鞘翅推动后翅回到静止位置,进一步支持了被动展开的假设。我们用一个能被动展开翅膀进行稳定可控飞行、并在着陆时整齐地收回翅膀的扑翼微型机器人验证了这一假设,展示了一种简单而有效的设计类昆虫飞行微型机器的方法。
▲ Abstract:
Here we demonstrate that rhinoceros beetles can effortlessly deploy their hindwings without necessitating muscular activity. We show that opening the elytra triggers a spring-like partial release of the hindwings from the body, allowing the clearance needed for the subsequent flapping motion that brings the hindwings into the flight position. After flight, the beetle can use the elytra to push the hindwings back into the resting position, further strengthening the hypothesis of passive deployment. We validated the hypothesis using a flapping microrobot that passively deployed its wings for stable, controlled flight and retracted them neatly upon landing, demonstrating a simple, yet effective, approach to the design of insect-like flying micromachines. |
