1. A computer-assisted medical system comprising:
a manipulator cart;
a memory storing instructions; and
a processor communicatively coupled to the memory and the manipulator cart, the processor configured to execute the instructions to:
define a path whereby the manipulator cart is to navigate from an initial location to a target location;
identify a navigation condition associated with a navigation of the manipulator cart along the path from the initial location to the target location;
define, based on the navigation condition, a propulsion limitation configured to be imposed on operator-provided commands related to a propulsion of the manipulator cart during the navigation of the manipulator cart along the path; and
direct the manipulator cart to navigate, in a bifurcated navigation control mode, along at least part of the path from the initial location to the target location;
wherein, in the bifurcated navigation control mode, the processor is configured to execute the instructions to autonomously control a steering of the manipulator cart while allowing operator control of the propulsion of the manipulator cart based on the operator-provided commands as limited by the propulsion limitation.
