Remora suckerfish can attach to a wide diversity of marine hosts, however, their detachment mechanism remains poorly understood. Through analyzing high-speed videos, we found that the detachment of the live remora ( Echeneis naucrates ) is a rapid behavior that can happen within 240 ms. We separate this remarkable behavior into three stages: 1) lamellae folding down and soft lip curling, 2) disc raising and 3) complete detachment. To quantitatively investigate the detachment behavior, we fabricated a multi-material biomimetic disc and utilized it to study each stage of the detachment process. In stage one, we found that folding down lamellae is essential for decreasing the detachment resistance (vertical interfacial force and friction force) of the suction disc. Also, curling up the soft lip to breaking the adhesive seal reduced the vertical pull-off force up to 94 times. During disc raising in stage 2, we found that the partially flexible base (Young’s modulus: ∼3 MPa) of ...

remora 吸盘的分离：运动学和仿生机器人模型。

Remora 吸盘鱼可以附着在各种各样的海洋宿主上，但是，它们的分离机制仍然知之甚少。通过对高速视频的分析，我们发现活鱼（Echeneis naucrates）的脱离是一种可以在240毫秒内发生的快速行为。我们将这种非凡的行为分为三个阶段：1) 薄片向下折叠和柔软的唇部卷曲，2) 椎间盘抬高和 3) 完全脱离。为了定量研究脱离行为，我们制造了一个多材料仿生盘，并利用它来研究脱离过程的每个阶段。在第一阶段，我们发现折叠薄片对于降低吸盘的分离阻力（垂直界面力和摩擦力）至关重要。还，卷起软唇以破坏粘性密封，垂直拉脱力减少了 94 倍。在第 2 阶段的椎间盘提升过程中，我们发现 ...
