[en] We propose a simple model for a motor that generates mechanical motion by exploiting an entropic
force arising from the topology of the underlying phase space. We show that the generation of
mechanical forces in our system is surprisingly robust to local changes in kinetic and topological
parameters. Furthermore, we find that the efficiency at maximum power may show discontinuities.
