PlanToNamedConfiguration('relaxed_home') fails #10

Closed garthz closed 9 years ago

garthz commented 9 years ago

The current herbpy build apparently cannot run the entry-level tutorial for PlanToNamedConfiguration().

The following fails from the ipython prompt: robot.PlanToNamedConfiguration('relaxed_home')

invocation: rosrun herbpy console.py --sim

Workspace packages, all up to date: comps herb_description herbpy interactive_markers or_cdchomp or_interactivemarker or_ompl or_urdf owd prpy

Tail of extensive error output:

I think you need the package or_parabolicsmoother.this is a recently added dependency and we forgot to update the tutorial.

Yes, adding or_parabolicsmoother fixes the problem, thanks.

@garthz, would you please update the tutorial if you haven't already? Sorry for the inconvenience.

garthz commented 9 years ago

Good idea. I added a link from the herbpy tutorial to the new catkin/hydro guide. I added the required package to the recommended list.
