On my system I get WARNING: bad srv: std_srvs/String and the command rossrv show std_srvs/String says: Unknown srv type [std_srvs/String]: Cannot locate message [String] in pack...

You need to copy the newly built plugin to the CoppeliaSim directory, overwriting the previous one.

You don't need to modify CMakeLists.txt, simply copy devel/lib/libsimExtROSInterface.so to the CoppeliaSim root directory.

You are probably still using the old plugin.

Replace while true with while sim.getSimulationState()~=sim.simulation_advancing_abouttostop

That depends on the many properties of the joints you have set.

CoppeliaSim can export to a variety of formats, but this will work only for the model/meshes/textures.

If you can't find a suitable export format you can always write your won exporter. Have a look at simAddOnFunc_minimalisticExporter.lua.

Can you be more clear in what you want to achieve?

Maybe use a threaded script if you need to use sim.wait and continue the simulation meanwhile.

I don't think the order between sibling items can be set by the user. Only parent/child can be changed. Current ordering appears to be undefined (perhaps is dependent on the underlying data structures). Lexicographic order might make sense for scene trees with a large branching factor (although I th...

You need to add std_msgs/String to meta/services.txt and recompile the plugin, as the message says.
