A hybrid aerial-aquatic microrobot

Hybrid RoboBee

Flapping wing locomotion is seen in aerial insects (e.g. honeybees) and in aquatic species (e.g. sea plankton). Through constructing 3D CFD numerical simulations and performing at-scale flapping experiments, I found that flapping propulsion in air and in water can be achieved in the same device by appropriately changing the operating frequencies. Building on this theoretical analysis, I developed a 175mg, hybrid aerial-aquatic, flapping wing, microrobot that is capable of flying, swimming, transitioning from air-to-water, and impulsively taking off from the water surface.
