Read the first 7 Safety Standards & Compliance in Robotics flashcards as text

  1. What is the maximum allowable transient contact force per ISO/TS 15066 for the hand/finger area when a cobot makes unintended contact?

    Answer: 140 N

    ISO/TS 15066 Annex A specifies a quasi-static force limit of 140 N for the hand/finger body region during unintended collaborative robot contact.

  2. In FANUC DCS, a 'Position Check' violation triggers which type of robot stop by default?

    Answer: Category 0 (power removed immediately)

    A DCS Position Check violation triggers a Category 0 stop — immediate removal of servo power — because it indicates the robot has exceeded its defined safe working envelope.

  3. Which body administers the RIA (Robotic Industries Association) standards that FANUC robots must comply with in the US?

    Answer: A3 (Association for Advancing Automation)

    RIA is now part of A3 (Association for Advancing Automation), which develops and administers the ANSI/RIA R15.06 standard for industrial robot safety in the US.

  4. When validating a safety-rated monitoring function on a FANUC robot, what must be verified per ISO 13849-1 to confirm the achieved Performance Level (PL)?

    Answer: MTTFd, DCavg, CCF measures, and system architecture (category)

    ISO 13849-1 PL validation requires calculating MTTFd (mean time to dangerous failure), DCavg (diagnostic coverage), applying CCF (common cause failure) measures, and verifying the architectural category.

  5. A FANUC robot cell uses a safety-rated door interlock. According to ANSI/RIA R15.06, what must happen before the safeguarding device can be muted to allow material transfer?

    Answer: A muting function with defined time limits and additional safeguards must be in place

    Muting (temporarily suspending) a safeguarding device is only permitted when a properly designed muting function with time/position limits and supplemental safeguards is implemented per ANSI/RIA R15.06.

  6. According to ISO 10218-2, who bears primary responsibility for the overall safety of an integrated robotic system (the complete robot cell)?

    Answer: The system integrator

    ISO 10218-2 places primary responsibility for the safety of the integrated robot system on the system integrator, who designs and installs the complete cell.

  7. What is the purpose of 'speed monitoring' in FANUC's DCS compared to a simple software speed override?

    Answer: DCS speed monitoring is a safety-rated function executed by a dedicated safety CPU independent of the main motion controller

    FANUC DCS speed monitoring runs on a dedicated safety-rated CPU that independently verifies TCP speed, providing a hardware-level safety function that is separate from and not defeatable by the main motion controller.
