A surgical tool for use with a surgical system is disclosed. The surgical tool comprises a housing containing three drive motors and three non-concentric rotatable output members, a modular shaft assembly comprising three rotatable drive shafts coupled to the three non-concentric rotatable output members, an end effector comprising a first jaw and a second jaw, and a motion conversion assembly. The motion conversion assembly is operably coupled to one of the drive motors and an axial drive assembly. The motion conversion assembly is configured to convert a rotational motion of one of the three rotatable drive shafts to an axial motion. The application of the axial motion to the axial drive assembly approximates the first jaw from an open position to a closed position and performs an actuation stroke within the end effector.
