What is the purpose of interlocking in KUKA robot safety measures?

Interlocking in KUKA robot safety measures is crucial for ensuring that specific functions of the robot can only be activated when predetermined safety conditions are met. This approach is designed to minimize the risk of accidents and to protect both operators and equipment during the robot's operation. By implementing interlocking systems, the robot can function safely only when it is in a condition deemed safe, such as when safety guards are in place or when operators are at a safe distance.

The other options do not align with the primary function of interlocking. Preventing unauthorized access is more related to security protocols rather than safety prevention through interlocking mechanisms. Allowing immediate activation of all robot functions contradicts the very nature of interlocking, which serves to establish necessary precautions before activation. Maintaining battery life is generally more relevant to operational efficiency than to safety protocols, and it does not pertain to the safety interlocking function within KUKA robots. Therefore, option C accurately captures the essence of interlocking as a safety measure in KUKA robots.
