The version of Gazebo/drcsim loaded using

sudo apt-get install drcsim

works when invoked with just


but has the following fatal errors when invoked as

roslaunch atlas_utils atlas.launch
Error [] Unable to find value for key[link_name]
Error [] Unable to find value for key[link_name]
Exception [] Couldn't Find Parent Link[]
Error [] LoadJoint Failed

These messages are repeated about 28 times. This message is at the end:

Error [] Missing element description for [link_name]
[gazebo-2] process has finished cleanly
log file: /home/cga/.ros/log/e01679e8-a55e-11e2-9de5-d4bed9fd5ae1/gazebo-2*.log

Trying to invoke our copy of the atlas urdf (the one that works with drcsim-nightly installed) with

gazebo world

has the same problem.

Same problem here... Just before the error there are several warnings about SDF conversion. Not sure if it is related. Regards, LR

Thanks for the report. A fix is being prepared in gazebo pull request #451, to be included in a forthcoming gazebo 1.6.3 release.
