I am starting work on my first collaborative robot system and need to do the risk assessment. Is the risk assessment for a collaborative system still the task based risk assessment that I have done many times in the past or doe the risk assessment for a collaborative robot system need to be done in a different way?
We are a canadian manufacturer of an autonomous weeding robot for the ag industry. What are the certifications we need to obtain given the fact the robot is autonomous and will be roaming the fields with no supervision? Thanks Luc Labbé, CEO Nexus Robotics 418-570-1196

Is it ok to have the light curtains of a cell muted, during teach mode, without having some type of interlock partition key switch with a visual indication such as a rope with signage attached? I am concerned about having someone come in to the cell from the loading/unloading side, while teaching is being performed.
We are building a system that has an inspection area with a knee wall and inner and outer light curtains. The inner curtains are muted unless the outer curtains are broken, then the inner curtains are active. The standard states that in this Point of Operation walk through situation, presence must be continually sensed in the area. We have used Line of Sight in the past meaning someone would have to intentionally reset the outer curtains while being able to see if someone was in the point of operation area. Is this acceptable or do we need to use a mat or horizontal curtains to continuously monitor the area?
I am trying to understand safe distances better as I am relatively new to shared workspace. I have an application that uses a safety camera and an area scanner. I also have a shared workspace between the robot and an operator. The operator will manually load parts into the shared workspace while the robot is working on other items. The safety camera is used to divide the shared workspace and the robot operating space and the area scanner is mounted below the shared workspace. What is considered the hazard(robot, pinch points, etc.) in this situation?

In R15.06 part 2 section 4.2, item c) reads as follows: Manual intervention – the layout should be designed to allow tasks requiring manual intervention to be performed from outside the safeguarded space. Where this is not practicable and when the intervention requires powered movements of the machine(s), appropriate enabling devices shall be provided. My question is, does free-driving the robot count as powered movement with respect to the quoted section of the standard above?
we are looking to add a automated spot weld center using turn table application requiring us to spot weld 3 brackets to housing 11 spot welds. my question is I received quotes for the centers one with Daihen/OTC/Nachi and another using Fanuc robots. I was told the Nachi would be better for the operation more speed and would be better overall for the application. can get any comments or recommendations on this .

I am trying to determine if our robot cell is considered "collaborative" or not. Within R15.06-2012, a collaborative workspace is a "workspace within the safeguarded space where the robot and human can perform tasks simultaneously during production operation". In our cell, the robot and human do not perform tasks "simultaneously", instead they perform tasks in the same space but in sequence. For example, assume there is a "Location A" within our workspace. In our operation the robot moves to Location A, then performs work and then leaves Location A, (but remains in the workspace). Then the human enters the workspace, moves to Location A and performs work, and then leaves the workspace altogether. And it is not the intention for the human to interact with the robot while the human is in the workspace, such as passing material to it, etc. However, in theory I suppose the robot CAN perform tasks simultaneously while the human is in the workspace as it is not locked out, it is simply programmed to remain stowed in a home position. So...is this considered a collaborative workspace? Our confusion/debate is centered around the phrase "can perform tasks simultaneously" and the intuition that the workspace does not feel collaborative but the standard seems to indicate that it is. Just want to make sure we are meeting the appropriate requirements. Thanks for the help.
Hello RIA, My question is, what is the average power consumption of a typical warehouse/logistics robot? I found on this site that a typical medium-sized industrial robot, with about 100-kg payload, has an average power consumption of 7.35 kW. I would assume a typical warehouse/logistics robot would be smaller and therefore have lower average power consumption. Thank you
