The SurferBot is a vibrating robot that resides at an air-water interface and relies on self-generated waves to propel steadily along the surface. In this video, we highlight its simple design and construction, elucidate the physical mechanisms underlying its propulsion, and document its versatility for operation in a variety of configurations. Such interfacial microrobots have been proposed for use in applications related to environmental monitoring, surveillance, and pedagogy.
