Which of these is NOT an injury that can occur when working with robots?

• A. Being struck by a robot
• B. Being caught between a robot arm and other machine or object
• C. Being struck by objects or tools used by a robot when released accidentally
• D. All of these are injuries

Answer: (D)

Working around robots involves several injury hazards because robot systems move with speed and force, and their tools or payloads can be unexpectedly released. Being struck by a robot occurs when the arm or end effector contacts a person during operation. Being caught between a robot arm and nearby machinery or objects creates pinch or crush points that can injure limbs or joints. Objects or tools released by a robot can strike a worker if a tool slips or if a grip fails. Since each of these is a plausible injury scenario, there isn’t an option describing a non-injury; the statement that all of these are injuries is the correct one. In practice, safeguards like guarding, interlocks, safe operating procedures, and locking out equipment help prevent these hazards.
