Question

Quizplus · Accepted Answer

A physical barrier is the best choice for guarding a robot's work envelope as it creates a physical separation between the operator and the hazardous robot. This prevents accidental contact and injury. Photoelectric, pullback, and electromechanical devices may be useful in certain situations but they do not provide the same level of protection as a physical barrier.
