Robotic and/or surgical devices, systems, and methods include kinematic linkage structures and associated control systems configured to facilitate preparation of the system for use. A set-up mode employs an intuitive user interface in which one or more joints of the kinematic linkage are initially held static by a brake or joint drive system. The user may articulate the joint(s) by manually pushing against the linkage with a force, torque, or the like that exceeds a manual articulation threshold. Articulation of the moving joints is facilitated by modifying the signals transmitted to the brake or drive system. The system may sense completion of the reconfiguration from a velocity of the joint(s) falling below a threshold, optionally for a desired dwell time. Embodiments of the invention can provide for manual movement of a platform supporting a plurality of surgical manipulators or the like without having to add additional input devices.

The medical device of claim 3, wherein the processor is further configured to filter the second torque to increase sensitivity to transients in the second manual effort. 6. The medical device of claim 1, wherein the processor is further configured to cause the drive unit to mitigate one or more of friction of the linkage during the manual articulation toward the second pose of the linkage, effects of gravity on the linkage, and momentum of the linkage. 7. The medical device of claim 1, wherein the processor is further configured to determine that the velocity of the manual articulation is below the threshold velocity for a threshold dwell time before determining that the linkage is at the second pose of the linkage. 8. The medical device of claim 7, wherein the processor is further configured to cause the drive unit to facilitate a reversal of a direction of the manual articulation without inhibiting the manual articulation until the manual articulation has been below the threshold velocity for the threshold dwell time. 9. The medical device of claim 1, wherein the processor is further configured to cause the drive unit to inhibit the manual articulation from the second pose of the linkage while a third manual effort against the linkage remains below the articulation threshold. 10. The medical device of claim 1, wherein: the linkage comprises a set-up structure having a proximal base, a platform, and a joint between the proximal base and the platform; andthe platform supports a plurality of surgical manipulators, each manipulator comprising an instrument holder configured to releasably receive a surgical instrument; andthe manual articulation from the first pose to the second pose alters positions of the plurality of surgical manipulators relative to a surgical site. 11. The medical device of claim 1, wherein: the linkage includes a surgical manipulator having an instrument holder and a cannula interface, the instrument holder being configured to releasably receive a surgical instrument, and the cannula interface being configured to releasably receive a cannula;the surgical manipulator is configured to pivotably move a shaft of the surgical instrument within a minimally invasive surgical aperture adjacent the cannula so as to manipulate an end effector of the surgical instrument; andthe processor is further configured to cause, in response to the cannula being mounted to the cannula interface, the drive unit to inhibit manual articulation of the linkage by a third manual effort against the linkage exceeding the articulation threshold. 12.
