Unable to find or download file (gz sim buoyant_tethys.sdf) #274

Hi,
I installed the lrauv simulator following the instructions "Using a containerized workspace" in the Wiki. Everything went right, but when I tried to run the first example: gz sim buoyant_tethys.sdf I got the following error: Unable to find or download file.
Nonetheless, if I execute the control commands to move the vehicle, they seem to work fine LRAUV_example_controller and LRAUV_keyboard_teleop as I can see in the terminal that the LRAUV's parameters changes.

I installed the simulator in a fresh new Ubuntu 22.04, with new Docker and nvidia-docker. I installed and ran it on a remote PC through ssh.

Do you know why I got this error?

Thanks!

Did you source the workspace?

Yes, I did . install/setup.bash inside ~/lrauv_ws workspace

Ah OK I reallized we removed the gz sim buoyant_tethys.sdf example with #272. I've updated the wiki with new instructions. Run gz sim empty_environment.sdf.

Also, I have to say that inside the folder ~/lrauv_ws/src/ I only have the /lrauv folder not the /lrauv-applicaion folder, and therefore I cannot execute the "Run the MBARI LRAUV application" commands explained in the examples . I have missed some step?

Ok, that looks like it works, however I'm not onsite (I'm connected to a remote machine through SSH), and I received some errors related to "qt.qpa.xcb: could not connect to display" which I think they are normal, I will test it on site later on. Thanks!

Ah yes we should put a header on that. The LRAUV application is no longer available as it is MBARI's own IP. @hidmic do we know how we plan on exporting the MBARI controller? If not we should remove those instructions or put a heading saying "For MBARI users only."

I have an MBARI collaboration agreement which give me access to their LRAUV Bitbucket repository. In that case, what is the best case to integrate lrauv-applicaiton into ignition? should I colon the lrauv-application in the lrauv_ws/src folder and build it there (inside the container I just created )? or is there another better way? how will it interact with ignition, transparently by the user? Thanks so much for your help!

@caguero , @hidmic , @adityapande-1995 please advice when you guys wake up. I'm sorry I don't have access to the MBARI stuff so they will be better suited to answer your question.

@imasmitja if you have such an agreement, then you have access to simulation usage instructions. Look for the Tools/gz folder.

@arjo129 MBARI folks should build and push the binaries in a Docker image, like they used to. The infrastructure is there.
