A computer-assisted medical system includes a flexible catheter configured to articulate along a degree of freedom, an actuator disposed at a proximal portion of the flexible catheter, an actuator sensor, and an articulation sensor. The actuator is configured to actuate the flexible catheter along the degree of freedom, the actuator sensor is configured to provide actuator sensor signals representing movement of the actuator, and the articulation sensor is configured to provide articulation sensor signals representing articulation of the flexible catheter. The computer-assisted medical system further includes a controller coupled to the actuator and configured to, based on detecting an abnormality in a first articulation sensor signal, determine an articulation estimate of the flexible catheter based on a model of the flexible catheter applied to a first actuator sensor signal, and control the actuator based on the articulation estimate.

Method and system for controlling flexible devices in presence of abnormal sensor signals

A method of detecting a tool being received in a medical system, the method including receiving, in a tool recognition assembly having a first reader with a first detection zone, the tool having a first target. The method also includes acquiring first sensor data from the first reader for the first detection zone and detecting an indication of an absence of the first target when the first sensor data is within a first pre-determined threshold range and logging the absence indication. The method also includes creating an insertion signature associated with the tool being received in the tool recognition assembly by combining, in a chronological sequence, the absence and presence indications from the first reader. The method further includes comparing the insertion signature to a predetermined set of model insertion signatures and determining a characteristic of the tool being received in the tool recognition assembly based on the comparing.

A method comprises monitoring movement of an elongate device and receiving user input commanding motion of the elongate device. The method also comprises determining a mode of operation based on at least one of the monitored movement or the received user input and adjusting a property of the elongate device based on a profile associated with the mode of operation. Adjusting the property of the elongate device includes maintaining the property of the elongate device substantially the same during a first interval, reducing a rigidity of the elongate device at a first rate during a second interval and reducing the rigidity of the elongate device at a second rate, different from the first rate, during a third interval.

Inter-operative switching of tools in a robotic surgical system

Techniques for controlling a moveable component include a moveable component and a controller. The controller is configured to control motion of the moveable component according to a state machine comprising a first and second state. In the first state, the controller holds the moveable component at a current position. The controller transitions the state machine from the first state to the second state in response to detecting a displacement of the moveable component, due to a disturbance, from the current position for longer than a first predetermined duration of time. In the second state, the controller commands the moveable component to perform a motion. The controller remains in the second state until a stop condition is detected, even if the disturbance ends before the stop condition is detected. The controller transitions the state machine from the second state to the first state in response to detecting the stop condition.

Techniques for controlling a moveable component

In a coupled control mode, an operator directly controls movement of an associated manipulator with an input device while indirectly controlling movement of one or more non-associated manipulators, in response to commanded motion of the directly controlled manipulator, to achieve a secondary objective. By automatically performing secondary tasks through coupled control modes, the system's usability is enhanced by reducing the operator's need to switch to another direct mode to manually achieve the desired secondary objective. Thus, coupled control modes allow the operator to better focus on performing tasks and to pay less attention to managing the system.

A medical instrument system includes actuators, a medical instrument, and a control system operably connected to the actuators. The medical instrument includes an end portion and transmission systems, each of which couples the end portion to an actuator of the actuators such that the actuators are operable to drive the transmission systems to move the end portion. The control system is configured to execute operations including determining a difference between a current configuration of the end portion and a desired configuration of the end portion, and operating the actuators to apply tensions to the transmission systems based on the difference and based on constant offset tensions. The constant offset tensions are independent of current tensions experienced by the transmission systems.
