I’m trying to modify the tutorial file” cobotta_900” into my UR20 version, for RMP follow target test.
I tried to run the file” follow_target_example.py” but can’t figure out the “root_joint” path problem.(pic below)
the only one clue is that when I’m tried to use the lula test widget, I saw the “root_joint”, in the selected Articulation, but in the ur 20 prim path there is no path called “root joint”
I’m confused — if the prim path doesn’t show a “root_joint”, then where does the error mentioning “root_joint” come from?
please help.
