Claim 17:
18. A surgical robotics table, comprising:
a base having a plurality of actuators;
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, 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 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 floor when the casters are resting on, and supporting the base above, the floor, and
a first electric drive motor in mechanical communication with the first axle to drive the axle and thereby drive the base along the floor,
wherein each of the plurality of actuators is controllable to advance a respective, coupled caster thereby tilting the base and raising the first drive wheel off the floor,
the housing of the drive assembly is configured to rotate freely about the vertical axis of the drive assembly, and the drive assembly is arranged with an asymmetrical weight distribution such that when the first drive wheel has been raised off the floor, the drive assembly housing rotates, with respect to the body of the base and due to gravity, to a different orientation, and
when the first drive wheel is raised off the floor, one of the casters is also raised off the floor and becomes free to rotate toward the different orientation.
