Which of the following is not a component of the Dual Safety Check (DCS) system?

• A. Auto Run Programming Check
• B. Emergency Stop Control
• C. Joint Position Check
• D. Cartesian Speed Check

Answer: (A)

Dual Safety Check centers on real-time safety validation during robot operation, using two independent verifications to ensure safe motion before it proceeds. One verification monitors each joint to keep positions within allowed limits, preventing configurations that could be unsafe. The other verification tracks the robot’s speed in Cartesian space to ensure the end effector never moves faster than a safe threshold. An Emergency Stop Control is a fundamental safety feature that can immediately halt the robot if a hazardous condition is detected, and it fits squarely within the DCS approach of providing rapid safety responses. In contrast, Auto Run Programming Check is about validating programs or run-time logic before or during execution, not the live safety checks that govern motion. Therefore, Auto Run Programming Check is not a component of the Dual Safety Check system.
