On the mobility and efficiency of mechanical systems

It is shown that self-locomotion is possible for a body in euclidian space, provided its dynamics corresponds to a non-quadratic hamiltonian, and that the body contains at least 3 particles. The efficiency of the driver of such a system is defined. The existence of an optimal (most efficient) driver is proved.
