[Robotics] Ask for: link/append/import returns object(s) instance(s)

[Pierrick Koch]

Thanks Gilberto,

it wors fine for link_append:
####
bpy.ops.object.select_all(action='DESELECT')
bpy.ops.wm.link_append(directory="/usr/local/share/data/morse/components/robots/atrv.blend/Object/",
link=False, files=[{'name': 'ATRV'}, {'name': 'Wheel.4'}, {'name':
'Wheel.3'}, {'name': 'Wheel.2'}, {'name': 'Wheel.1'}])
for obj in bpy.context.selected_objects:
  print(obj)
####

but unfortunately not for Collada (the import method select the last
wheel)...

Cheers,
