    Abstract: A system comprises an instrument having a bendable portion with first and control elements extending in the bendable portion and a control system operably coupled to an actuator and a sensor. The control system operates to, while the bendable portion is in a neutral position, command the actuator to move the first control element a first amount until slack is removed from the first control element and command the actuator to move the second control element a second amount until slack is removed from the second control element. The control system also receives a first control element calibration position after moving the first control element the first amount and receives a second control element calibration position after moving the second control element the second amount. The control system also commands the actuator to bend the bendable portion from the neutral position and determine a resulting shape of the bendable portion.

    Abstract: A surgical instrument may comprise a housing and a shaft a shaft extending within the housing. The shaft may include first and second ends. The shaft may be configured for rotation in response to either a robotic actuation of the shaft or a manual actuation of the shaft. The surgical instrument may also comprise a receiving member coupled to the first end of the shaft. The receiving member may be configured to releasably couple to a driver of a robotic manipulator to receive the robotic actuation from the driver to rotate the shaft and articulate an instrument component coupled to the shaft. The surgical instrument may also comprise a manual actuation component coupled to the second end of the shaft and extending from the housing. The manual actuation component may be configured to receive the manual actuation to rotate the shaft and articulate the instrument component coupled to the shaft.
