1. A surgical instrument for use with a robotic system comprising a first rotatable driver and a second rotatable driver, said surgical instrument comprising:

  • an end effector, comprising;

    a jaw;

    an anvil;

    a staple cartridge removably positioned in said jaw; and

    an end effector spine;

    a shaft assembly, comprising;

    a longitudinal axis;

    an articulation joint, wherein said end effector is rotatable relative to said longitudinal axis about said articulation joint;

    a shaft spine rotatably connected to said end effector spine across said articulation joint; and

    a cutting instrument movable along said longitudinal axis between a starting position and an ending position; and

    a control system, comprising;

    a cutting drive configured to displace said cutting instrument toward said ending position in response to the first rotatable driver of the robotic system; and

    a shaft rotation arrangement configured to rotate said shaft assembly about said longitudinal axis in response to the second rotatable driver on the robotic system, wherein the rotation of said shaft assembly does not displace said cutting instrument within said shaft assembly, and wherein said cutting drive and said shaft rotation arrangement are separate and distinct.
