1. A method for operating a power tool having an output member, comprising:

  • monitoring, by a controller disposed in the power tool, rotational motion of the power tool about an axis of the output member, using a rotational motion sensor disposed in the power tool;

    determining, by the controller, a user-desired rotational direction for the output member about the axis;

    determining, by the controller, an actual rotational direction of the power tool about the axis, using the monitored rotational motion of the power tool; and

    driving, by a motor disposed in the power tool, the output member to simulate ratcheting movement of the output member in the user-desired rotational direction.
