1. A surgical cart for supporting a robotic arm, comprising:
a vertically-extending support column;
a carriage movably coupled to the support column and configured to carry a robotic arm; and
a braking mechanism including:
a screw defining a longitudinal axis and rotatably supported in the support column;
a nut threaded to the screw and coupled to the carriage such that axial translation of the carriage and in turn the nut along the screw causes the screw to rotate about the longitudinal axis defined by the screw; and
a brake configured to selectively engage the screw to prevent rotation of the screw and in turn axial movement of the nut and the carriage along the longitudinal axis defined by the screw.
