    Abstract: A system may comprise a flexible delivery device including a tool channel extending therethrough and an elongated instrument configured to extend within the tool channel. The elongated instrument may include a flexible section and a rigidizable section. The system may also include a selective rigidization system at least partially extending within the elongated instrument and a sensor system configured to determine position information for the rigidizable section relative to a distal portion of the delivery device. The selective rigidization system, responsive to the position information, may be configured to transition a portion of the rigidizable section of the instrument from a bendable state to a rigid state.

    Abstract: Techniques for active and semi-active damping include a system including a base, a first linkage, a second linkage, and a processor. A proximal end of the first linkage is coupled to the base. The first linkage is configured to support a first instrument. The first linkage includes a first link, a second link, and a first damper coupling the second link to the first link. A proximal end of the second linkage is coupled to the base. The second linkage is configured to support a second instrument. The second linkage incudes a third link, a fourth link, and a second damper coupling the fourth link to the third link. The processor is configured to detect a movement or vibration of the first linkage caused by motion of the second linkage and control the second linkage to mitigate the detected movement or vibration of the first linkage.

    Abstract: A surgical system includes methods and systems for damping vibrations. The surgical system can include one or several moveable set-up linkages. A passive, active, or semi-active damper can be connected with one or several of the set-up linkages. The damper can mitigate a vibration arising in one of the set-up linkages and the damper can prevent a vibration arising in one of the linkages from affecting another of the set-up linkages. The active and semi-active dampers can be controlled with a feedback or a feed-forward model. In some embodiments, the system includes a first link supported by a base, a second link, a damper having a variable portion coupling the first link to the second link, and a processor. The processor is configured to detect a movement or a vibration of the second link and adjust the variable portion of the damper based on the detected movement or vibration.

    Abstract: A robotic arm for a minimally invasive surgical system includes a parallel spherical five-bar linkage adapted to spherically rotationally move a robotic surgical tool coupled to the parallel five-bar spherical linkage about a remote center of spherical rotation. The five-bar spherical linkage is posed in only a range of compact poses. A constraint limits the parallel five-bar spherical linkage to only the range of compact poses.
