论文摘要
大自然在空气流体界面上发展了各种推进策略。受蜜蜂（Apis Mellifera）启动的生存机制的启发，我们在这里提出了冲浪者：一种厘米尺度的振动机器人装置，该机器人使用类似的流体动力机制在流体表面上自动prop，作为震惊的蜜蜂。这种低成本且容易组装的设备能够通过由波浪生成的，不平衡的动量通量产生的力来进行直线运动，从而达到每秒几厘米的速度上的速度。由于毛细管波场的冲浪尺寸和幅度的尺寸，我们发现推进力的大小与蜜蜂的大小相似。除了对冲浪者推进的流体力学的详细描述外，还讨论了其他冲浪机动的模式。更广泛地说，我们建议可以使用冲浪程序来探索流体接口处的活动和驱动颗粒的基本方面，以及机器人和流体力学教学法。
Nature has evolved a vast array of strategies for propulsion at the air-fluid interface. Inspired by a survival mechanism initiated by the honeybee (Apis mellifera) trapped on the surface of water, we here present the SurferBot: a centimeter-scale vibrating robotic device that self-propels on a fluid surface using analogous hydrodynamic mechanisms as the stricken honeybee. This low-cost and easily assembled device is capable of rectilinear motion thanks to forces arising from a wave-generated, unbalanced momentum flux, achieving speeds on the order of centimeters per second. Owing to the dimensions of the SurferBot and amplitude of the capillary wave field, we find that the magnitude of the propulsive force is similar to that of the honeybee. In addition to a detailed description of the fluid mechanics underpinning the SurferBot propulsion, other modes of SurferBot locomotion are discussed. More broadly, we propose that the SurferBot can be used to explore fundamental aspects of active and driven particles at fluid interfaces, as well as in robotics and fluid mechanics pedagogy.
