"Our research group studies a lot of biologically inspired fluid mechanics problems, such as how snails use slime for locomotion, or how water striders walk on water, " Nasto says.

我们小组从生物界获取灵感，研究了大量相关流体力学问题，比如蜗牛如何运用黏液进行移动、水黾如何在水上行走。

Using porous, super water-repellant nickel foam to fabricate the three supporting and two jumping legs, the group made a robot that could leap more than 5.5 inches, despite weighing as much as 1, 100 water striders.
