    a working tip coupled to the elongated member;

    a sensor configured to detect a user-imparted hand tremble motion of the elongated member;

    a flexible beam element of the elongated member located in-between the handle portion and the working tip, and configured to reversibly bend, extend, or rotate with respect to the longitudinal axis;

    an actuator physically coupled to the flexible beam element and configured to reversibly bend, extend, or rotate the flexible beam element with respect to the longitudinal axis; and
