A surgical instrument. Various embodiments of the surgical instrument include an end effector that has a moveable cutting implement. A main drive shaft assembly operably interfaces with the end effector for transmitting an actuation motion to the movable cutting implement therein. A gear drive train is connected to the main drive shaft assembly. The gear drive train is actuated by a motor that is configured to receive control signals from a robotic system. Various embodiments include a sensor arrangement that operably interfaces the end effector to communicate forces experienced by the end effector to the robotic system.
