Which item is NOT considered a core FANUC robot system component?

• A. Safety fences
• B. Controller
• C. Software
• D. Mechanical Unit

Answer: (A)

The main idea is distinguishing the robot’s core components from safety infrastructure. A FANUC robot system is built around three fundamental elements: the mechanical unit (the robot arm and end effector that perform the work), the controller (the brain that handles motion control and logic), and the software (the programming environment and control algorithms that drive the robot). Safety fences, while essential for protecting people and ensuring safe operation, are external safety equipment—not part of the robot’s control, motion, or programming. They provide a protective boundary but don’t contribute to the robot’s function itself. So the item that is not a core FANUC robot system component is the safety fences.
