In prioritizing the safety of a robotic system, which item is ranked first?

• A. People
• B. Robot
• C. External Device
• D. Workpiece

Answer: (A)

In safety prioritization for robotic systems, protecting people comes first. The reason is simple and non-negotiable: human safety has the highest obligations in any risk assessment. If a hazard could injure someone, that risk must be eliminated or reduced to a level as low as reasonably practicable before considering risks to the robot, external devices, or the workpiece. This mindset drives design choices like implementing safeguards, emergency stops, safe operating speeds and forces, interlocks, and clear human–robot interaction protocols so that people are never exposed to preventable harm.

If the risk to a person is adequately controlled, then attention can turn to protecting the robot itself, auxiliary devices, or production outcomes. However, those aspects are subordinate to preventing harm to humans. So the item ranked first in prioritizing safety is people.
