我们报告最近的努力，在设计和建造的水上行走机器的灵感来自昆虫和蜘蛛。自然水步行者的大小，比例和动态的基本物理约束枚举和类似的机械装置的设计标准。我们报告的设备能够划船沿着表面，跳跃的表面和攀爬的自由表面变形的。最关键的设计约束是器械重量轻且不润湿。微尺度制造技术和新的人造材料，如疏水涂层和热致动导线的实施。使用高速电影摄影和流动可视化，我们比较我们的设备的功能和动态与他们的自然同行。
We report recent efforts in the design and construction of water-walking machines inspired by insects and spiders. The fundamental physical constraints on the size, proportion and dynamics of natural water-walkers are enumerated and used as design criteria for analogous mechanical devices. We report devices capable of rowing along the surface, leaping off the surface and climbing menisci by deforming the free surface. The most critical design constraint is that the devices be lightweight and non-wetting. Microscale manufacturing techniques and new man-made materials such as hydrophobic coatings and thermally actuated wires are implemented. Using highspeed cinematography and flow visualization, we compare the functionality and dynamics of our devices with those of their natural counterparts.
