    Abstract: A system comprises a first cannula comprising a proximal end and a cannula opening at the proximal end. The system further comprises a teleoperated surgical instrument, and a manually operated surgical instrument configured to be inserted into the cannula opening. The system further comprises a teleoperated manipulator, a controller, and a first position sensor coupled to the teleoperated surgical instrument, the first position sensor configured to provide a first sensor input to the controller. The system further comprises a second position sensor coupled to the manually operated surgical instrument, the second position sensor configured to provide a second sensor input to the controller, the second sensor input comprising an insertion depth of the manually operated surgical instrument into the first cannula. The system further comprises a reference fixture coupled to the first and second position sensors and to the teleoperated manipulator, the reference fixture being movable with the teleoperated manipulator.

    Abstract: Systems and methods for controlling an elongate device include a console. The console includes a first recess and a removable first input control for controlling motion of the medical device, The console also may include one or more first sensors located about the first recess that detect motion of the first input control and detect operator contact with the first input control. The console also may include an integrated display screen arranged to display status information for the medical device. In some embodiments, the first input control controls an insertion depth or steering of the medical device, and may be in the form of a scroll wheel forming a part of a removable control assembly

    Abstract: A method for moving a manipulator arm. The manipulator arm includes a movable distal portion, a proximal portion coupled to a base, and joints between the distal portion and the base. The method involves calculating a first movement of the joints in accordance with a first objective. The method further involves calculating a second movement of the joints in accordance with a second objective. The first and the second movements are in a null-space of a Jacobian of the manipulator arm. The method also involves determining a combined movement of the joints by combining the first and second movements while limiting an overall magnitude of the combined movement without changing a direction of the combined movement, and/or combining the first and second movements while limiting a magnitude of the combined movement degree-of-freedom by degree-of-freedom. The method further involves driving the joints to effect the combined movement of the joints.

    Abstract: A medical instrument system includes a plurality of joints, a plurality of actuators, and a plurality of transmission systems. The transmission systems have proximal ends respectively coupled to the actuators. Each of the transmission systems have a distal end attached to an associated one of the joints to allow the transmission of a force for articulation of the medical instrument system. The system also includes a sensor coupled to measure a configuration of the medical instrument; and a control system coupled to receive configuration data, including a current configuration of a tip of the medical instrument from the sensor and a desired configuration of the tip of the medical instrument. Using the difference between the desired configuration and the current configuration of the tip of the medical instrument, the control system generates control signals for the actuators that cause the actuators to apply a set of tensions to the plurality of transmission systems.

    Abstract: Methods, apparatus, and systems for controlling a plurality of manipulator assemblies of a robotic system. In accordance with a method, a first plurality of sensor signals are received at a plurality of joint space interface elements from a plurality of connector input elements via a first mapping between the joint space interface elements and joints of the first manipulator assembly. The connector input elements are operable to couple to only one manipulator assembly at a time. The received first sensor signals are then processed with a joint controller so as to control the first manipulator assembly. A second plurality of sensor signals are then received from the connector input elements at the joint space interface elements via a second mapping different than the first mapping. The received second sensor signals are then processed with the joint controller so as to control a second manipulator assembly different than the first manipulator assembly.
