Robotic systems are provided for flexibility in assembly operations. A robotic system includes a suction module having a front side with a face shaped to match a mating component and a rear side with a coupling for a suction line. Openings extend through the face. The suction module defines internal passages connecting the coupling with the at least one opening through the face. An end-effector has a base plate, a mounting plate selectively moveable relative to the base plate, and a clamp. The suction module is selectively mounted to the mounting plate and releasably secured by the clamp. An actuator is mounted to selectively move the mounting plate and the suction module relative to the base plate.
