Actuator
An actuator is a device that helps machines move or control something in automated systems. Think of it as a muscle that makes things happen - it converts energy (like electricity or air pressure) into physical movement. For example, actuators can open and close valves, move robotic arms, or adjust manufacturing equipment. They're essential components in many automated systems, from simple automatic doors at supermarkets to complex industrial robots. When someone mentions actuators in their resume, they might have worked with electric, hydraulic, or pneumatic (air-powered) types.

Example Interview Questions
Senior Level Questions
Q: How do you approach troubleshooting a complex system with multiple actuators that isn't performing correctly?
Expected Answer: A senior engineer should describe a systematic approach: checking control signals, examining mechanical connections, using diagnostic tools, and mentioning the importance of documentation and safety procedures.
Q: How would you choose between different types of actuators for a new automation project?
Expected Answer: Should discuss factors like required force/speed, precision needs, environment conditions, maintenance requirements, and cost considerations in selecting appropriate actuators.
Mid Level Questions
Q: What maintenance procedures do you follow for actuator systems?
Expected Answer: Should explain regular inspection routines, lubrication schedules, performance testing, and preventive maintenance practices to ensure reliable operation.
Q: How do you ensure safety when working with actuator systems?
