甲蟲(chóng)和撲翼微型機(jī)器人翅膀的被動(dòng)展開(kāi)和收攏 ▲ 作者:Hoang-Vu Phan, Hoon Cheol Park & Dario Floreano ▲ 鏈接:https://www.nature.com/articles/s41586-024-07755-9 ▲摘要: 在此,我們展示了犀金龜可以毫不費(fèi)力地展開(kāi)它們的后翅,而不需要肌肉活動(dòng)。我們展示了打開(kāi)鞘翅會(huì)將像彈簧一樣的后翅部分從身體上釋放出來(lái),從而為隨后的拍打動(dòng)作提供所需的空間,從而使后翅進(jìn)入飛行位置。 飛行結(jié)束后,犀金龜可以利用鞘翅推動(dòng)后翅回到靜止位置,進(jìn)一步支持了被動(dòng)展開(kāi)的假設(shè)。我們用一個(gè)能被動(dòng)展開(kāi)翅膀進(jìn)行穩(wěn)定可控飛行、并在著陸時(shí)整齊地收回翅膀的撲翼微型機(jī)器人驗(yàn)證了這一假設(shè),展示了一種簡(jiǎn)單而有效的設(shè)計(jì)類昆蟲(chóng)飛行微型機(jī)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. |
