    (b) left and right drive mechanisms, coupled to said body, each of said left and right drive mechanisms comprising;

    a first traction element engaging a ground surface and transmitting a driving force between the vehicle and the ground surface;

    a second traction element, engaging the ground surface and transmitting a driving force between the vehicle and the ground surface;

    a first arm, coupled to the first traction element for relative rotation about a first axis;

    a second arm, coupled to the second traction element for relative rotation about a second axis;

    a rotor member having a third axis, said rotor member coupled to the body for rotation about said third axis, and coupled to said first arm and said second arm for relative rotation about the third axis;

    a first drive motor coupled to drive the first traction element;

    a second drive motor coupled to drive the second traction element;

    a first transmission, driven by the first motor and engaging the rotor member so that driving the first traction element simultaneously rotates the rotor member relative to the first arm; and
