A robotic surgical tool is disclosed. The robotic surgical tool can comprise an end effector comprising a firing member; a drive system responsive to a motor-driven input; and a proximal housing comprising a retraction mechanism. The retraction mechanism can comprise a control responsive to a manual input. The control can be rotatable in a first direction through a retraction motion and rotatable in a second direction through a reset motion. The retraction mechanism can further comprise a clutch coupled to the control. The clutch can be configured to drivingly engage the drive system as the control rotates through the retraction motion to supply a proximal retraction stroke to a firing bar and drivingly disengaged from the drive system as the control rotates through the reset motion to prevent any displacement of the firing bar by the retraction mechanism until the control is reset for a subsequent retraction motion.
