The Mechanical Unit is a component of the FANUC robot system.

• A. The Keyboard is a component.
• B. The Mechanical Unit is a component of the FANUC robot system.
• C. The Safety fences are a component.
• D. The Air compressor is a component.

Answer: (B)

Recognizing what parts are considered components of a FANUC robot system. The Mechanical Unit refers to the actual moving hardware—the arm, joints, and drive mechanisms that produce motion—so it is a fundamental component inside the robot system. A keyboard is an operator interface used to interact with controllers, not part of the robot’s mechanical system. Safety fences provide workspace protection and are not internal robot components. An air compressor may power external pneumatic devices but is not a built-in robot component. Thus, the Mechanical Unit correctly identifies a component of the FANUC robot system.
