1. A surgical robotics table, comprising:
a base;
a support extending upwardly from the base; and
a table top on the support, wherein the table top is configured to support a patient,
wherein the base comprises
a body,
a plurality of casters mounted to the body of the base, wherein each of the casters is configured to rotate freely about a vertical axis of the caster, and
a drive assembly coupled to the body of the base, the drive assembly comprising
a housing mounted to the body of the base and configured to rotate relative to the body about a vertical axis of the drive assembly,
a first drive wheel configured to revolve with a rotating, horizontal first axle, wherein the first axle is mounted to the housing such that the first drive wheel is in contact with a horizontal floor when the casters are resting on, and supporting the base above, the floor,
a first electric drive motor in mechanical communication with the first axle to drive the axle and thereby drive the base along the floor, and
a second drive wheel configured to revolve with a rotating, horizontal second axle that is mounted to the housing such that the second drive wheel is in contact with the floor simultaneously with the first drive wheel,
wherein the drive assembly supports the first drive wheel and the second drive wheel such that the first drive wheel and the second drive wheel exert a torque on the housing to cause rotation thereof, relative to the body and about the vertical axis of the drive assembly while the first drive wheel and the second drive wheel are driven differentially.
