1. A surgical instrument, comprising:

  • a channel member configured to support a staple cartridge;

    an anvil coupled to the channel member;

    a rotatable drive screw positioned in the channel member;

    a firing member configured to be advanced by the rotatable drive screw;

    a sled member configured to be advanced to eject staples from the staple cartridge to form a staple pattern during a firing cycle, wherein the sled member is positioned at least partially distal to the staple pattern at a completion of the firing cycle;

    an elongate shaft assembly coupled to the channel member;

    a housing coupled to the elongate shaft assembly, wherein the housing comprises more than two rotatable disks couplable to a robotic device; and

    a closure system comprising;

    a linear camming member coupled to the anvil; and

    a rotatable member coupled to the linear camming member, wherein;

    a rotation of the rotatable member in a first direction operates to urge the anvil into a close approximation to the channel member; and

    a rotation of the rotatable member in a second direction operates to release a clamp load on the anvil and move the anvil to an unclamped position, wherein a first one of the more than two rotatable disks is coupled to the rotatable member.
