A surgical tool is disclosed. The surgical tool has a tool mounting portion having a tool mounting housing, a tool mounting plate, and a coupler to couple a shaft assembly having an articulation section to the tool mounting portion. An articulation mechanism is located within the tool mounting portion and is configured to receive a proximal end of the shaft assembly to articulate the articulation section of the shaft assembly. The articulation mechanism has a cam mechanism operative to articulate the articulation section of the shaft assembly. An interface mechanically and electrically couples the tool mounting portion to a manipulator.
