Actuators
Actuators are like the muscles of robots and automated machines. They are devices that convert energy (usually electrical, hydraulic, or pneumatic) into physical movement. Think of them as the parts that make things actually move - whether it's a robotic arm lifting something, a door opening automatically, or a manufacturing machine performing its tasks. When you see this term in a resume, it usually means the person has experience working with the components that create motion in automated systems. Similar terms you might see include "motors," "servo drives," or "motion control devices."

Example Interview Questions
Senior Level Questions
Q: How would you approach selecting actuators for a new robotics project?
Expected Answer: A senior engineer should discuss factors like load requirements, speed needs, precision requirements, environment conditions, and cost considerations. They should also mention experience with different types of actuators and their pros and cons.
Q: Tell me about a challenging actuator-related problem you solved in a previous project.
Expected Answer: Looking for answers that demonstrate leadership, problem-solving abilities, and deep understanding of how actuators work in real-world applications. Should include troubleshooting methods and solution implementation.
Mid Level Questions
Q: What are the main types of actuators and when would you use each?
Expected Answer: Should be able to explain basic differences between electric, hydraulic, and pneumatic actuators in simple terms, and give examples of appropriate applications for each type.
Q: How do you maintain and troubleshoot actuator systems?
Expected Answer: Should describe basic maintenance procedures, common problems, and troubleshooting steps. Should mention safety considerations and preventive maintenance.
Junior Level Questions
Q: What is an actuator and what does it do in a robotic system?
Expected Answer: Should be able to explain in simple terms that actuators create movement in robots and give basic examples of different types of movement (rotating, pushing/pulling, etc.).
Q: What safety considerations are important when working with actuators?
Expected Answer: Should demonstrate basic understanding of safety protocols, emergency stops, and awareness of potential hazards when working with powered mechanical systems.
