Abstract

Systems of granular rotors (Vibrots), that is, small devices that convert linear
vibrational motion into rotation by frictional impact, are of scientific interest
since they could reveal various types of collective behavior. Looking at an
isolated Vibrot, we note at least two dierent dynamical modes, depending on the
parameters of the vibrational driving. By means of Finite Element simulations,
we reveal the driving mechanism for both cases which may be correspondingly
identified as ratcheting and tumbling. The transition between both modes
resembles period doubling in certain bouncing ball problems leading eventually
to chaotic motion in such systems.
