Under ANSI/RIA R15.06, what is the minimum safe distance formula used when calculating the safety distance for a presence-sensing device?
Answer: Ds = K × (Ts + Tc + Tr + Tbm)
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.
Which OSHA standard primarily governs industrial robot safety in general industry workplaces in the United States?
Answer: 29 CFR 1910.212
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.
In ISO 10218-1, what does the term 'collaborative operation' specifically require regarding robot speed when a human is detected in the shared workspace?
Answer: Robot speed must not exceed 250 mm/s in the shared space
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.
A FANUC robot's Dual Check Safety (DCS) function monitors which parameters to enforce safe zones?
Answer: Joint angles, TCP position, and TCP speed simultaneously
FANUC DCS simultaneously monitors joint angles, TCP Cartesian position, and TCP speed to enforce configurable safe zones and speed limits.
When performing a risk assessment for a robotic cell per ISO 12100, what is the correct sequence of steps?
Answer: Identify hazards → Estimate risk → Evaluate risk → Risk reduction
ISO 12100 prescribes: identify hazards first, then estimate the risk of each hazard, evaluate whether risk is acceptable, then apply risk reduction measures.
Which category of safety-rated stop in ISO 10218 allows the robot to maintain power and position while stopping all motion?
Answer: Category 2 stop
Category 2 (protective stop) maintains power and position hold while stopping motion, allowing quick resumption without re-homing — used in collaborative robot scenarios.
What is the purpose of the 'teach pendant enable device' (deadman switch) on a FANUC teach pendant during T1 or T2 mode?
Answer: It enables motion only while held in the intermediate position, stopping motion if released or fully gripped
The deadman switch enables robot motion only when held in the intermediate (half-pressed) position; releasing it or pressing it fully both trigger a stop, protecting the operator.
