A surgical tool for use with a robotic system includes an end effector comprising at least one component portion selectively movable between first and second positions and a shaft including an axially movable portion in operable communication with the at least one selectively movable component portion and a rotatably movable portion in operable engagement with the axially movable portion. An initial rotation of the rotatably movable portion causes the axially movable portion to move the selectively movable component portion from the first position into an intermediate position at a first rate. A subsequent rotation of the rotatably movable portion in a same direction causes the axially movable portion to move the selectively movable component portion from the intermediate position to the second position at a second rate different from the first rate.

The surgical tool of claim 1 wherein said another component portion of said end effector comprises a surgical staple cartridge and wherein one of said at least one component portion that is selectively movable comprises an anvil that is selectively movable between a first open position, said intermediate position, and a second closed position relative to said surgical staple cartridge. 3. The surgical tool of claim 2 wherein said surgical end effector further comprises a cutting instrument that is axially movable within said surgical staple cartridge between a starting position and an ending position in response to a firing motion applied thereto by said transmission arrangement. 4. A surgical tool for use with a robotic system that has a tool drive assembly that is operatively coupled to a control unit of the robotic system that is operable by inputs from an operator and is configured to provide at least one rotary output motion to at least one rotatable body portion supported on the tool drive assembly, said surgical tool comprising: a surgical end effector comprising at least one component portion that is selectively movable between first and second positions relative to at least one other component portion thereof; andan elongated shaft assembly operably coupled to said surgical end effector, said elongated shaft assembly comprising: an axially movable portion in operable communication with said at least one selectively movable component portion of said surgical end effector; anda rotatably movable portion in operable engagement with said axially movable portion wherein an initial rotation of said rotatably movable portion causes said axially movable portion to move said selectively movable component portion of said surgical end effector from said first position into an intermediate position at a first rate, wherein subsequent rotation of said rotatably movable portion in a same direction causes said axially movable portion to move said selectively movable component portion of said surgical end effector from said intermediate position to said second position at a second rate, wherein said surgical tool further comprises a transmission arrangement in operable engagement with said at least one rotatable body portion supported on the tool drive assembly and in operable engagement with said rotatably movable portion of said elongated shaft assembly to apply said rotary output motions thereto from said at least one rotatable body portion to cause said axially movable portion of said elongated shaft assembly to move said selectively movable component portion between said first and second positions, and wherein said first rate is greater than said second rate. 5. A surgical tool for use with a robotic system that has a tool drive assembly that is operatively coupled to a control unit of the robotic system that is operable by inputs from an operator and is configured to provide at least one rotary output motion to at least one rotatable body portion supported on the tool drive assembly, said surgical tool comprising: a surgical end effector comprising at least one component portion that is selectively movable between first and second positions relative to at least one other component portion thereof; andan elongated shaft assembly operably coupled to said surgical end effector, said elongated shaft assembly comprising: an axially movable portion in operable communication with said at least one selectively movable component portion of said surgical end effector; anda rotatably movable portion in operable engagement with said axially movable portion wherein an initial rotation of said rotatably movable portion causes said axially movable portion to move said selectively movable component portion of said surgical end effector from said first position into an intermediate position at a first rate, wherein subsequent rotation of said rotatably movable portion in a same direction causes said axially movable portion to move said selectively movable component portion of said surgical end effector from said intermediate position to said second position at a second rate, wherein said surgical tool further comprises a transmission arrangement in operable engagement with said at least one rotatable body portions supported on the tool drive assembly and in operable engagement with said rotatably movable portion of said elongated shaft assembly to apply said rotary output motions thereto from said at least one rotatable body portion to cause said axially movable portion of said elongated shaft assembly to move said selectively movable component portion between said first and second positions, wherein said another component portion of said end effector comprises a surgical staple cartridge and wherein one of said at least one component portion that is selectively movable comprises an anvil that is selectively movable between a first open position, said intermediate position, and a second closed position relative to said surgical staple cartridge, and wherein said rotatably movable portion comprises a closure member in threaded engagement with said axially movable portion. 6. The surgical tool of claim 5 wherein one of said closure member and said axially movable portion has a series of threads formed thereon and the other one of said closure member and said axially movable portion has a thread engagement member thereon. 7. The surgical tool of claim 6 wherein said series of threads comprises a proximal thread section that transitions into a distal thread section. 8. The surgical tool of claim 7 wherein said proximal thread section is coarser than said distal thread section. 9. The surgical tool of claim 8 wherein said elongated shaft assembly is coupled to a tool mounting portion that operably supports said transmission arrangement thereon, said tool mounting portion attachable to said tool drive assembly such that said transmission arrangement is in operable engagement with said at least one rotatable body portion supported on the tool drive assembly of the robotic system. 10.
