    Abstract: A robotic system includes a camera having an image frame whose position and orientation relative to a fixed frame is determinable through one or more image frame transforms, a tool disposed within a field of view of the camera and having a tool frame whose position and orientation relative to the fixed frame is determinable through one or more tool frame transforms, and at least one processor programmed to identify pose indicating points of the tool from one or more camera captured images, determine an estimated transform for an unknown one of the image and tool frame transforms using the identified pose indicating points and known ones of the image and tool frame transforms, update a master-to-tool transform using the estimated and known ones of the image and tool frame transforms, and command movement of the tool in response to movement of a master using the updated master-to-tool transform.

    Abstract: Control systems and methods for a medical instrument use measurements to determine and control the tensions that actuators apply through instrument transmission systems. The use of tension and feedback allows control of a medical instrument having transmission systems that provide non-negligible compliance between joints and actuators even when the positions of joints cannot be directly related to actuator positions. One embodiment determines joint torques and tensions from differences between desired and measured joint positions. Another embodiment determines joint torques and tensions from differences between desired and measured positions of a tip of the instrument. Determination of tensions from joint torques can be performed using sequential evaluation of joints in an order from a distal end of the instrument toward a proximal end of the instrument.

    Abstract: Tool force information is provided to a user of a telesurgical system using an alternative modality other than force reflection on a master manipulator, such as providing the information on user-visible, user-audible, or haptic “buzz” or “viscosity” indicators, so as to allow expanded processing, including amplification, of the information, while not significantly affecting the stability of the telesurgical system or any closed-loop control systems in the telesurgical system.

    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: A surgical device comprises a tube including a proximal segment and a distal segment and a plurality of force transmission elements coupled to the tube. The force transmission elements are actuatable to alter the distal segment of the tube between a flexible state and a stiffened state. The device also comprises a plurality of routing members. Each routing member is coupled to a wall of the tube. The routing members are configured to receive and route the force transmission elements along a length of the tube while permitting the length of the tube to flex and compress. The device also comprises a decoupling structure that generates a reduced force transmitted to the proximal segment when an applied force is applied to the distal segment by the force transmission elements.
