A vehicle, for driving over a ground surface, has a body with a left side, a right side, a front and a back. The vehicle includes left and right drive mechanisms. Each mechanism includes first and second traction elements for engaging the ground surface and transmitting a driving force between the vehicle and ground surface. Each mechanism includes first and second arms coupled to the first and second traction elements for relative rotation about first and second axis respectively. Each mechanism includes a rotor having a third axis, the rotor coupled to the body for rotation about the third axis and coupled to the first and second arms for relative rotation about the third axis. The mechanism includes first and second drive motors for driving the first and second traction elements and first and second transmissions, driven by the first and second motors and engaging is the rotor. Driving the first and second traction elements simultaneously rotates the rotor relative to the first and second arms, respectively.

[ What is claimed is:] [1.] A movable vehicle comprising:(a) a body having a left side, a right side, a front and a back; and(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 tothe 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; anda second transmission, driven by the second motor and engaging the rotor member so that driving the second traction element simultaneously rotates the rotor member relative to the second arm. [12.] A vehicle, for driving over a ground surface, the vehicle comprising:(a) a body having a left side, a right side, a front and a back;(b) a left drive mechanism; and(c) a right drive mechanism, wherein each of the left drive mechanism and the right drive mechanism comprises:a first wheel having a first axis;a second wheel having a second axis;a pulley having a third axis and coupled to the body for rotation about the third axis;a first arm coupling the first wheel to the body, rotatable relative to the first wheel about the first axis, and rotatable relative to the pulley about the third axis;a second arm coupling the second wheel to the body, rotatable relative to the second wheel about the second axis, and rotatable relative to the pulley about the third axis;a first drive motor for rotating the first wheel about the first axis relative to the first arm;a second drive motor for rotating the second wheel about the second axis relative to the second arm;a first belt driven by the first motor and engaging the pulley; anda second belt driven by the second motor and engaging the pulley. The vehicle of claim 12, wherein each of the left drive mechanism and the right drive mechanism further comprises a plurality of friction disks normally irrotatably coupled to each other and carried along the third axis, the plurality of friction disks hindering relative rotation of the pulley member, first arm and second arm relative to each other. The vehicle of claim 13, wherein each of the left drive mechanism and the right drive mechanism further comprises:a splined shaft member extending along the third axis and carrying the plurality of friction disks, the pulley, the first arm and the second arm; anda spring maintaining compressive engagement between the plurality of friction disks, the pulley, the first arm and the second arm. The vehicle of claim 14, wherein each of the left drive mechanism and the right drive mechanism includes first, second, third and fourth friction disks in the plurality of friction disks, the first friction disk being located inboard of the pulley, the second friction disk being located between the pulley and the first arm, the third friction disk being located between the first arm and the second arm, and the fourth disk being located outboard of the second arm.
