Which of the following is not typically considered a safeguarding measure in a robot cell?

• A. Safety fences
• B. Light curtains
• C. Work piece
• D. Floor markings

Answer: (C)

In safeguarding robot cells, protective measures are things that physically block access or quickly stop and detect intrusions to keep people safe. Safety fences provide a physical barrier around the robot’s work area, and light curtains act as a deterring sensor that stops the robot if someone crosses the boundary. Floor markings help people see where it’s safe to stand or move, guiding safe operation. The work piece, though essential to the process, is not a protective device and does not prevent access, detect intrusion, or stop the robot. It’s simply the object being handled, so it’s not considered a safeguarding measure.
