What is the role of an observer during safety-critical debugging?

• A. To monitor for unsafe actions and ensure safety protocols are followed.
• B. To operate the robot remotely.
• C. To write code in real time.
• D. To fix hardware faults.

Answer: (B)

During safety-critical debugging, the observer’s main job is to watch for anything unsafe and make sure safety rules are followed. This means keeping an eye on actions that could put people at risk, verifying that safety interlocks, personal protective equipment, and test procedures are in place, and being ready to halt the test if something looks dangerous. The observer provides an independent safety check, maintaining a safe boundary between people and the robot so that issues can be identified without exposing anyone to harm. Tasks like writing code or actively operating the robot belong to developers or operators, while the observer stays focused on risk assessment and ensuring that safety protocols are upheld.
