Andy,
I have to trust my inspection staff at events. If they ask that you cover a pinch point, it is likely that they are evaluating that individual robot based on past experience. I have seen things that would turn your hair grey and fall out. (Have you seen my picture?) As for some of the others, how many of you using chains can operate the mechanism without power? Can gravity cause it to move even if it hasn't ever done that? Can another person bump into your robot in the queue or on the floor and cause that mechanism to move? If you answered yes to any of these, someone is going to have a hand near or in your robot at some point.
