中文摘要：

基于水黾腿部疏水原理，提出一种水上微小机器人腿部用钢丝制备方法，同时利用Young—Laplace方程对其漂浮机理进一步进行详尽的力学分析，即水黾腿部材料与水的接触角越大，能够获得水面提供的支撑力也越大。

英文摘要：

The bio -mimetic water strider robot appeals a growing number of scholars＇ interest re- cently. The preparation of legs is a hot area of research. A method preparation of legs based on the principle that water stride could wake on water surface is introduced, in this paper, based on the Young- Laplace equation,the reason why the water stride can wake on water is further studied, which the larger the contact angle of the leg surface is, the larger the support force is.
