Hi John,
Thanks for those ideas. I think the pause-world option looks like the
most applicable scenario -- pausing the simulator while things
magically appear is as reasonable as anything else. In the mean time,
I created a single URDF file with my table as one link and the objects
as 30 separate links attached to the table via "floating" joints. If
I can pick up the objects without the table coming along (which is
what "floating" implies to me), then I think I'll go with this
approach.
