US Patent 12102398 Automated instrument preload engage/disengage mechanism

Techniques for automated engagement and disengagement of a preload include a computer-assisted apparatus. The computer-assisted apparatus includes an instrument manipulator assembly including a preload assembly and a controller coupled to the instrument manipulator assembly. The controller is configured to move the instrument manipulator assembly to a fully withdrawn position and command the preload assembly to engage a preload. In some embodiments, engaging the preload causes the preload assembly to assert a preload force on a motor pack of the instrument manipulator assembly. In some embodiments, the controller is further configured to move the instrument manipulator assembly to a home position after the preload is engaged.
