第一个能在水上跳跃的机器人诞生

韩国首尔大学的一个研究团队通过研究水黾创造出了能在水面上跳到空中的机器人。研究论文发表在《科学》期刊上。

当研究小组用高速摄像机观察水黾在水面跳跃时,他们注意到,水黾的长腿是逐渐加速的,这样水的表面不会过快地后退并失去与其腿的接触。

应用一种漂浮在液体上的灵动圆筒理论模型,作者们发现,水黾腿的最大用力总是低于水面张力所能承受的最大力。

为了在他们的机器人中重新创建这一受控的加速,研究人员使用了一种扭矩反转弹射(TRC)机制,它能产生一个最初的小型扭矩且扭矩会逐渐增加-但它绝不会超过水的表面张力。

高速摄影机同时揭示,水黾会将其腿扫向内测,目的是为了将其腿压向水面的时间最大化,并因此使得总体用力最大化;这种新的概念也被应用于机器人以帮助它们实现腾跳。

在具备足够轻的重量、修长肢体及恰当的物理机制时,这些机器人有效地模仿了它们在自然界的为人们提供灵感的水黾。
