Explanation:

• "Relays" are switches which open state and closed state of circuits electronically or electromechanically. "Relays" regulate electrical circuits through the opening and closing connections in another circuit.
• An "actuator" is a mechanical device which takes energy and converts the energy into some sort of motion.
• A "stepper motor" is of a synchronous electric motor kind, which alters digital pulses toward mechanical shaft rotation.
• A "servo motor" is electrical devices which rotate or push an item with high precision.
