    It is not perpetual motion. Given enough time, they will stop swinging, as there is a force from friction at the joints. Furthermore, there are batteries powering this. Perpetual motion is defined as needing no input energy to continue.

    By the Second Law of thermodynamics, true perpetual motion is IMPOSSIBLE. No matter what. There is no nor will there ever be a perpetual motion formula.
