ANSI/RIA R15.06-2012, Part 1, 5.9.2 requires an indication, clearly visible from within the safeguarded space, of those robot(s) that have been activated shall be provided. How is this normally accomplished?

I'm looking for solutions for presence sensing that can be mounted from above. My first thought was some sort of 2D image recognition that could compare the current image to the "safe" image. We can paint the floor if contrast is required. The only product I could find that was similar to what I was looking for is the Pilz SafetyEYE. We don't need three dimensional monitoring, and the the zone it is looking at is probably too small. We would normally use laser scanners for this, but there are not any good locations to mount them on the floor. All help is appreciated.

I am working through a risk assessment and I'm trying to reconcile a situation where where a forge tending robot may hit somebody working within the die space of the press. This would be a hazard during die change, servicing the tool, prep, etc... I've identified this to be a medium risk. The obvious solution is to require that the robot be locked out during these activities but that seems like it would fall under the categories of Admin. Controls and/or Complementary Protective Measures which means they are not good enough for a medium risk. Any advice on this or perspective would be greatly appreciated.

We are migrating from the R1506-1999 standard to the R1506-2012 format. So several questions. 1. Can we continue to use the R1506-1999 standard if we choose to do so? 2. With the R1506-2012 standard, do we need to attempt to gain a “negligible” status, or is “low” suffice? Or is that for us to define? 3. Can we apply the term “prevented” or “effectively mitigated by design” to physical barriers, someone can overcome, defeat or remove them if they really want. Even if they are at the defined standard of 55". Thanks. Your review and feedback is appreciated.

According to RIA 15.06-2012, Part 1, Section 5.13, the manufacturer is required to design the robot so the "axes are capable of being moved without the use of drive power in emergency or abnormal situations". Some manufacturers elected to make this feature as a purchase option. Who is responsible to ensure that this feature is available to the operators? The robot manufacturer? ...the Integrator? ...or the end user/purchaser?

Have a manual load station in body shop, loading area is inside a safeguarded area protected by vertical and horizontal light screens as well as internal fencing preventing the operator from entering the actual robot area from this space. The opening for part loading into a fixture is minimized on the sides to the part size but it is open above due to the size of the part and ergo reasons to allow the operator to load. The fencing just in front of the 1m wide loading area is only 1.2m high (not the minimum 1.4m) due to ergo reasons, while the fence on either side is ~2.5m tall. We do not have a reach over/under/through hazard as the robot is a Safe Robot and interlocked through our safety PLC to prevent entry while an operator is loading. Question is, does this area need to be protected to prevent someone from climbing or clambering over this 1.2m fence? There is nothing on the operator side which acts as a step, we do have a full lock/tag/test program in place and have fully integrated gates and safety systems installed (latest Euchner MGB system). I could not find anything in the standard or questions which talks about this type of entry.

I would like to install a collaborative robot in my facility. I need to safeguard the floor around the robot and plan to use 4 safety area scanners. I plan to use three zones (a machine slow zone via the warning zone, a collaborative zone with one set of OSSDs, and a stop zone with another set of OSSDs. Is this an acceptable safety set up?

I design automation cells and regularly have conveyor openings in fencing. I've read through the RIA safeguarding manual but can't seem to figure out the proper distance I need to have hazards from the fence/tunnel end. The best I've come up with is treating a hole in the fence bigger than 4.7" as a reaching over scenario which doesn't quite seem correct.

If a European Cobot integrator developes a Robot or Cobot system and he develops it in accordance to the ISO/TS 15066:2016 standards would that be enough to integrate it at a US customer site or is an additional safety assessment in ANSI standards required?

What clause addresses that robot teach pendants must be interlocked for robots with overlapping restricted space?

We have purchased and have been reviewing R15.06 to obtain some direction on the following scenario: If we have an engineer that is teaching another engineer to program a robot, and both need to be in the operating area as part of the process, how do we handle control of the pendant? Our understanding of the standard is that only the person with control of the pendant can be within the operating area. If this is the full intent of the single-control concept, are there suggestions on how to handle training?

I am reviewing risk assessments for a robot system. The assessments seem to give a standard that should be meet and not what was actually done? I was trying to find a "gold " standard for a risk assessment. I looked at ISO/TR 14121-2 but their example didn't match a complex system. My searches online have not be fruitful. Is their a "gold" standard example of a robot risk assessment?

When using wire mesh fencing is there a requirement to purchase software options like FANUC DCS that would prevent the robot from sticking a welding nozzle through the openings in wire mesh fencing? It seems to me that you could have the robot stick the welding nozzle or wire through the mesh openings. Obviously we wouldn't intend anyone to program the robot that way but I am not sure if purchasing the DCS software is a requirement?

Does ANSI/RIA 15.06-2012 or any of the associated technical reports specify anything about the location, minimum quantity, spacing, etc., of emergency stop buttons on a robot cell safety enclosure? If not, are there other standards that would cover this?
