Claim 0:
1. A steerable drive wheel assembly comprising:
an outer housing defining a sheltered interior space, said outer housing including a top 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 connected to said first wheel through a first transmission, said second drive subassembly a second drive motor operatively connected to said second wheel through a second transmission,
a rotary bearing operatively disposed between said drive module and said intermediate suspension module for enabling rotational movement of said drive module relative to said intermediate suspension module about a generally vertical 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, and
an angular position sensor operatively disposed between said drive module and the intermediate suspension module,
wherein each of said first and second drive motors have an armature and a stator body, said first angular velocity sensor disposed between said armature and said stator body of said first drive motor, and said second angular velocity sensor disposed between said armature and said stator body of said second drive motor.
