Abstract: By comparing theoretical modeling, simulations, and experiments, we show that there exists aswimming regime at low Reynolds numbers solely driven by the inertia of the swimmer itself. This isdemonstrated by considering a dumbbell with an asymmetry in coasting time in its two spheres. Despitedeforming in a reciprocal fashion, the dumbbell swims by generating a nonreciprocal Stokesian flow, whicharises from the asymmetry in coasting times. This asymmetry acts as a second degree of freedom, whichallows the scallop theorem to be fulfilled at the mesoscopic scale.
