What is the role of a safety stand or tether during debugging?

• A. To secure power supply to avoid surges.
• B. To guide the robot's movement.
• C. To physically secure the robot or the operator to prevent sudden movement.
• D. To indicate status with LEDs.

Answer: (C)

The main idea here is safety through physical restraint during debugging. A safety stand or tether is used to physically secure either the robot or the operator so that unexpected or runaway movement can’t cause injury or damage. If motors stall, collide, or inertia causes a part to move suddenly, the tether helps keep everything in a controlled area and reduces the risk of contact with moving parts. This is about preventing sudden motion, not about managing power, guiding how the robot moves, or signaling status. Power protection and status indicators serve different safety and operational roles, while the tether specifically provides a hands-on safety barrier during testing.
