What role does safety light curtains play in the context of FANUC robots?

Safety light curtains are vital safety devices used in the context of FANUC robots, primarily designed to protect humans from accidental contact with moving parts of the robotic system. When a person or object interrupts the light beams emitted by the safety curtain, the robot can immediately stop its operations, preventing potential injuries that could occur if someone were to inadvertently enter the robot's working area.

This proactive safety measure allows for safer collaborative work environments where humans and robots operate in proximity. By ensuring that the robot ceases operation upon detection of an intrusion, safety light curtains significantly reduce the risk of accidents, helping to safeguard workers and comply with safety regulations.

While enhancing performance, preventing unauthorized access, and improving programming efficiency are important aspects of a robotic system's functionality, the primary role of safety light curtains is clearly centered on ensuring human safety by controlling the robot's operational behavior in response to potential threats.
