Abstract
A method for position correction of a machine relative to a work piece. The machine may be provided with an end effector. The work piece may be engaged with the end effector. A force or a moment resulting from engaging the work piece with the end effector may be measured. A pose error may be determined from the force and/or the moment, wherein the pose error may define a misalignment of the end effector. The end effector may be repositioned an amount equal to the pose error to correct the misalignment. One application may involve torqueing nuts with a nut runner, which may be accomplished through the use of an automated machine such as a robot.
