Claim 3:
4. A steerable drive wheel assembly comprising:
an outer housing defining a sheltered interior space, said outer housing including a top having opposing left and right edges, a right stabilizer arm extending downwardly from said right edge of said top, a left stabilizer arm extending downwardly from said left edge of said top,
an intermediate suspension module disposed at least partially within said sheltered interior space of said outer housing,
a drive module disposed below said intermediate suspension module, said drive module including a first drive subassembly having a first wheel and a second drive subassembly having a second wheel, said first and second wheels supported in side-by-side orientation for independent rotation about a common horizontal axis, said first drive subassembly including a first drive motor operatively corrected to said first wheel through a first transmission, said second drive subassembly including a second drive motor operatively connected to said second wheel through a second transmission,
a rotary bearing operatively disposed between said drive module and sad intermediate suspension module for enabling rotational movement of said drive module relative to said intermediate suspension module about a generally veritcal steering axis,
a first angular velocity sensor operatively associated with said first drive motor, a second angular velocity sensor operatively associated with said second drive motor,
an angular position sensor operatively disposed between said drive module and the intermediate suspsension module,
further including a serpentine energy chain disposed generally co-planar with said rotary bearing, said serpentine energy chain comprising a plurality of jointed conduit segments fixed at one end thereof to said outer housing and at another end thereof to said intermediate suspension housing.
