SurferBot: a wave-propelled aquatic vibrobot.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 theSurferBot: a centimeter-scale vibrating robotic device that self-propels on a fluid surface using analogous hydrodynamic mechanisms as the stricken honeybee.  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.
