FANUC Safety Standards & Compliance in Robotics 2

Question 1

Under ANSI/RIA R15.06, what is the minimum safe distance formula used when calculating the safety distance for a presence-sensing device?

Accepted Answer

Ds = K × (Ts + Tc + Tr + Tbm)

Answer

ANSI/RIA R15.06 uses Ds = K × (Ts + Tc + Tr + Tbm) where K is hand speed, Ts is stopping time, Tc is control system response, Tr is sensor response, and Tbm is brake monitor time.

Question 2

Which OSHA standard primarily governs industrial robot safety in general industry workplaces in the United States?

Accepted Answer

29 CFR 1910.212

Answer

29 CFR 1910.212 (General Machine Guarding) is the primary OSHA standard applicable to industrial robots in general industry, though 1910.147 (LOTO) also applies during maintenance.

Question 3

In ISO 10218-1, what does the term 'collaborative operation' specifically require regarding robot speed when a human is detected in the shared workspace?

Accepted Answer

Robot speed must not exceed 250 mm/s in the shared space

Answer

ISO 10218-1 specifies that during collaborative operation with speed and separation monitoring, robot TCP speed must not exceed 250 mm/s when a human is detected in the shared workspace.

Question 4

A FANUC robot's Dual Check Safety (DCS) function monitors which parameters to enforce safe zones?

Accepted Answer

Joint angles, TCP position, and TCP speed simultaneously

Answer

FANUC DCS simultaneously monitors joint angles, TCP Cartesian position, and TCP speed to enforce configurable safe zones and speed limits.

Question 5

When performing a risk assessment for a robotic cell per ISO 12100, what is the correct sequence of steps?

Accepted Answer

Identify hazards → Estimate risk → Evaluate risk → Risk reduction

Answer

ISO 12100 prescribes: identify hazards first, then estimate the risk of each hazard, evaluate whether risk is acceptable, then apply risk reduction measures.
