    Abstract: A system comprises an arm including a bendable section and a force transmission mechanism. The system also comprises an actuation mechanism coupled to the force transmission mechanism to bend the bendable section. The system also comprises an electronic data processor configured to receive sensor data about the bendable section and determine external force information about at least one of a magnitude or a direction of an external force applied to the arm from the sensor data. the processor is also configured to determine a pose of the bendable section from the sensor data and generate control information for the actuation mechanism to maintain the pose of the bendable section in a stationary configuration as the external force is applied to or withdrawn from the arm.

    Abstract: A medical system comprises a surgical device including a tracking system. The medical system also includes a memory storing anatomical data describing a patient anatomy. The medical system also includes a processor configured for generating a first model, that includes a set of anatomical passageways including a first proximal branch connected to a first distal branch, from the stored anatomical data describing the patient anatomy. The processor is also configured for determining, by the tracking system, a shape of an elongate flexible body of the surgical device positioned within the first proximal branch and the first distal branch of the set of anatomical passageways. The processor is also configured for computing, based on the determined shape of the elongate flexible body, a total set of forces acting on the set of anatomical passageways in response to the surgical device positioned within the first proximal branch and the first distal branch. The processor is also configured for deforming the first model into a second model of the anatomical passageways by adjusting at least one joint between branches in the set of anatomical passageways in the first model based on the total set of forces computed, to thereby change a pose of at least one branch through which the surgical device extends and at least one additional branch through which the surgical device does not extend.

    Abstract: A sensing system includes an off-axis coil in which wire is wound in loops about a roll axis and at an angle to the roll axis. In particular, the loops define respective areas that have a normal direction at a non-zero angle relative to the roll axis. A field generator can generate a variable magnetic field through the coil, and sensor logic can be coupled to the coil and configured to determine a measurement of a roll angle of the coil about the first axis using an electrical signal induced in the coil.
