We have a Kuka KR3 R540 robot that is being integrated into an existing system for vision inspection. The mounting location for the robot is in a tight area between a table and the lexan guarding. With this is being integrated into a portion of a system that was built by a different integrator, would we need to ensure the entire line is meets RIA standards prior to installing this robot or just the station it is being integrated into? Thank you.

We are working on a small 6-axis robot (7kg rated) application that has the safety enclosure much smaller than the robot reach. Hard stops on the axis points are not feasible for the required motion and the safety rated (Cat3, PLd) planes that can be programmed inside the enclosure are also not feasible due to safe distance calculations for "overshoot." We believe that our only option is to build an enclosure that is strong enough to contain the worst case inertia of the robot and payload, which would be coasting into the enclosure after crossing the safety plane. We can do the math to determine the inertia and can develop a simulated impact test on enclosure parts, but we don't know if there are any specific requirements, test methods, pass/fail criteria, documentation, etc. that we should be following. Is guard strength testing the correct solution for our application and is there any industry guidance on conducting this guard validation?

During an alternate LOTO procedure, where a Auto tech places the robot cell in maintenance mode (in order to work on it and power is needed), and then enters a multi robot cell, with multiple robots with his working envelope, what is the best scenario to have total and exclusive control of these numerous robot without be able to carry numerous teach pendants. I spoke to a MIOSHA rep and suggested that we create a very detailed risk assessment for this very specific alternate LOTO procedure The practicality is, how can an Auto tech carry 6 teach pendants with him while working on one or two robots? and still have total and exclusive control of the robots in his working envelope?

Is there a standard or best management practice or Checklist (preferred) to audit our Safety PLC controls to determine they are good during a risk assessment?

When training a new robot tech, we have 2 employees inside the work area. One has the pendant, in teach mode and the other is around them learning. My question is,"Does the other employee need a deadman switch?" Same thing with Maintenance personnel, "Do we need a deadman for each one in the cell?"

Hi. We are a robot integrator and also we design the robot cells(mechanical/guarding and electrical/safety circuits). I understand how to do the risk assessment part, but I'm confused about the checklists Part 1: Annex F and Part 2:Annex G of ANSI-RIA R15.06. We once hired a professional safety assessment firm on our behalf, and they only completed Part 1:Annex F. But we are now going to do our own assessments, and I feel as though we should be doing both. Any suggestions from another integrator/OEM? Do you fill out one of them or both? Thanks in advance.

Greetings, I am looking for reference material to cite in order to design a robot pedestal to be anchored to a cement floor. I am currently referencing a 2009 International Building Code and looking at allowable service load on embedded bolts. I am looking for reference material that will guide in the thickness and size of the base plate anchored to the floor as well as the required number/size of anchor bolts. I appreciate any help you can give. Thanks! James

Working on the the safety distance calculation for a Motoman robot with a light curtain guarding a forklift opening. We have FSU so I can do safety speed monitoring. My safety distance calculation currently includes human walking speed toward light curtain, and the combined stopping times of all the equipment from trip to robot stop. My questions are this. Do I need to include the distance traveled by the robot in this time? If so, how is this calculation possible prior to deployment of the cell? Second Motoman only rates the S L and U axes stop times, are the other axes irrelevant? Third, Motoman rates their stop times in Deg/S per axis. the example in RIA 15.06-2012 depicts mm/sec. Am I only concerned with ensuring my joint deg/s speeds are slow enough to stop within the required stop time with no regard to TCP speed?

We have several robotic palletizing cells. Each cell has a variety of case sizes that are being brought into the cell by roller conveyor. Some of our cases are large so the openings through the perimeter fencing are large enough for a person to crawl through if they got onto the in-feed conveyor. According to ANSI/RIA R15.06 - 2012 is there a safety standard that dictates what level of safety we need to have at these in-feed openings?

Hello, In R15.06-2012, it states that there is a maximum height a barrier can be above adjacent walking areas is 7". This is to ensure that no one can come in contact with the equipment inside. In applications where there could be large build ups of combustible dust or require routine cleaning of the area, is there a different height/ acceptable alternative to the 7"? Currently there is an installation which the eentire robot system is shutdown in order to clean the area due to the height of the guarding. This dramatically hinders production and could potentially cause employees to attempt to defeat the guarding to maintain the equipment. Thank you for your help

If I have a robot with a failsafe control unit, but it is not specifically a power and force limited model, can I myself build the necessary speed and torque limits into its motion to allow it to be used in a power and force limited operation?

Regarding redeployment of an older robot into a new system the RIA R15.06 1999 standard is pretty clear stating that as long as the robot was to standard when it was manufactured, it does not need to be upgraded. The rest of the system needs to be to the most current standard. Unfortunately, the 2012 standard does not specify anything about redeployment as far as I can find. Is the 1999 standard still valid? Is this spelled out in another standard or TR? If so please advise where I may find it.

If I'm not using any safety devices in my robot cell, what equation do I use for safety distance? I believe S = K*T + C is only for used with safety devices, due to the variables dealing with human interaction speeds. Is there a general equation for safety distance with regards to fencing and so maintenance personnel can't get pinned?

Would a safety gate interlocked door with a pl=d category 3 interlock, that stops robot motion, allow operators to enter a robot cell without LOTO or an enabling device, provided that their work won't require interaction with the robot and the gate key was placed into a lock box with the operators lock placed on the box?

ANSI/RIA R16.06-2012 5.3.15 says that when more than one person is required to be protected within the safeguarded space, that an enabling device shall be provided to each person. Does this mean that if only a singular person is entering the safe guarded space, they are not required to bring a teach pendant / enabling device into the cell with them?
