Abstract

Methods and apparatus for end effector control and calibration are described. The method may include detecting a signal in response to movement of a first tube relative to a second tube, the first tube driving movement of a clamp arm of the end effector. The method may further include determining a clamp arm position of the end effector relative to a ultrasonic blade of the end effector based on the signal. The method may also include adjusting a power output to the ultrasonic blade of the end effector based on the clamp arm position.
