robot_description not found in docker run about ariac

[zeidk]

The Error you get with parse_urdf can be ignored and is deprecated.
I will fix this so it works with moveit_example. It seems moveit is not properly loaded in the image.
I will try to get this to work before tomorrow.

[dan9thsense]

Any luck with this? We're getting pretty close to the qual runs and it takes time to get docker up and running well.

[zeidk]

Will be pushed today Dan. Had some power outage around here.
Thank you,

zeid

[zeidk]

Fixed it! I tried to push the new images to dockerhub but the website seems to be down or overloaded. Will try again tomorrow.

[dan9thsense]

Thanks for the fast action. I'll give it a try tomorrow.

[zeidk]

I will let you know when it's ready.

Dan,
I have pushed the new images to dockerhub and modified docker scripts here https://github.com/usnistgov/ariac-docker. The docker container will start moveit automatically (your issue was due because moveit was not started). Some teams may not use moveit at all , if this is the case then I will have to make some modifications to provide moveit as an option.

• I have added moveit_example_team in team_config as another submission example.

• The script run_team_system.bash will run a python script (moveit_example_docker.py) which is a simplified version of moveit_example.py.

  • moveit_example.py will not work in the competition mode because it calls the service /ariac/material_locations, which is forbidden in competition mode (see the Cheats section).

• You can try the new script with:

  • ./prepare_team_system.bash moveit_example_team
  • ./run_trial.bash moveit_example_team sample_docker

• Try the new docker images with your own code and let me know how it goes.

• I will update the wiki tomorrow to reflect those changes.

The good news is that it works, both with the example code and my code, both for single and all trials.
However, there are some issues:
There are some differences in performance, perhaps related to not having the GUI running, and I want to see what's going on. However, roslaunch nist_gear gear_playback.launch fails with the following errors:

[Err] [SystemPaths.cc:412] File or path does not exist["/home/ariac/ariac_ws/src/nist_gear/robots/torso/meshes/torso_base.dae"]
[Err] [MeshShape.cc:66] No mesh specified

[Err] [SystemPaths.cc:412] File or path does not exist["/home/ariac/ariac_ws/src/nist_gear/robots/ur10/ur_description/meshes/ur10/collision/base.stl"]

On my system, the correct paths are:
~/ariac_ws/src/ARIAC/nist_gear/robots/torso/meshes/torso_base.dae

and

~/ariac_ws/src/ARIAC/nist_gear/robots/ur10/ur_description/meshes/ur10/collision/base.stl

It is not obvious to me where those paths are being set or I would have tried changing them to get it to run.

[zeidk]

I will try this today and in the best case scenario I will only need to change the path in gear_playback.launch

Thank you

[zeidk]

Hi Dan,

Everything works fine on my end.
Do you have another nist_gear installed on your machine?
It seems the following line is pointing to libLogPlaybackPlugin.so located somewhere else (from a different nist_gear package).
args="-p $(arg state_log_path) -s $(find nist_gear)/../../lib/libLogPlaybackPlugin.so --pause $(arg extra_gazebo_args)" required="true" />
Can you try running everything in the gear_playback.launch using the command line?

[dan9thsense]

I pulled the code out of the launch file and ran it with absolute addresses and get the same result.
Here is the first command line:
rosrun gazebo_ros gzserver -p /home/dbarry/ariac_ws/ariac-docker/logs/sirius/march28/sample/gazebo/state.log -s /home/dbarry/ariac_ws/devel/lib/libLogPlaybackPlugin.so --pause --verbose __name:="gazebo" rosrun gazebo_ros gzclient __name:="gazebo_gui" output="screen" respawn="false"

and here is the second one (in another terminal):
rosrun gazebo_ros gzclient __name:="gazebo_gui" output="screen" respawn="false"

The output from the first one is:

At this point the gazebo window is open and the parts are in place, but there is no robot present. When I hit the play button, that is when the errors (in the first terminal window) appear:

Segmentation fault

The second terminal does not have any messages, it just hangs at this point.

Note that there is no directory on this machine corresponding to /home/ariac much less all those subdirectories listed below it.
I have no idea where it is getting that path name.

[zeidk]

Everything looks good until you press the play button. Gazebo opening without showing the robot is expected and the robot appears and moves when you press the play button.
Let me look into this issue today.

PS: The error in REST request is also unexpected.

zeid

[zeidk]

Can you email me ([email protected]) the file ~/.ariac/log/gazebo/state.log?

[dan9thsense]

File sent just now.

[zeidk]

I will look into this issue today.

[zeidk]

@dan9thsense Finally figured out how to fix this and the instructions can be found here. Please give it a try and close the ticket if you are satisfied.

[dan9thsense]

The state.log file is no longer showing up in the logs. The folder that used to contain it, gazebo, is no longer present either.

[zeidk]

@dan9thsense Can you check that you have the following at the top of your trial config file?

options:
   gazebo_state_logging: true

[dan9thsense]

Ah, that fixed it. I got it to work, thanks for figuring it out. However, the instructions are not quite correct. They say:

The easiest way to not get these errors is to create the following directory structure on the host

/home/ariac/ariac_ws/src, then copy the whole robots directory from ARIAC into

/home/ariac/ariac_ws/src

But what you actually need is to create the following directory structure on the host

/home/ariac/ariac_ws/src/nist_gear, then copy the whole robots directory from ARIAC into

/home/ariac/ariac_ws/src/nist_gear

Also, it is easy to make the mistake of adding the ariac/ariac_ws.... directory to your home user directory, but actually you need to add it like a new user folder, directly under the /home directory.

[zeidk]

oops, correct, I will fix this right away.

Thanks!

[stevegray954]

@zeidk Just saw your instructions -- instead of symlinking each file like you've got with your example, the easiest way is to symlink the directory

sudo mkdir -p /home/ariac/ariac_ws/src
sudo ln -s /home/YOUR_USER/ariac_ws/src/ARIAC/nist_gear /home/ariac/ariac_ws/src/
