Abstract: A surgical instrument designed to operate with a robotic platform is disclosed. The surgical instrument assembly includes a shaft, an end effector, a knife firing subsystem to actuate functions of the end effector, an articulation subsystem that is actuatable to articulate the end effector, an articulation joint about which the end effector articulates, a roll subsystem to roll the shaft, and a housing that couples to the robotic platform. A maypole tube is further provided, around which one or more articulation cables can wrap when the end effector is rotated.
