lbr_fri_ros2_stack: Missing dependencies

Thank you for the quick answer! The folder name might be related to some issues I am experiencing with getting my robot to run properly on humble 😄. I tried your fix:

• I ran the launch and waited ~15 minutes
• To clarify I am seeing the loading screen with “Preparing your world” but in the background gazebo opened showing the GUI and a completely black viewport. When I click the loading screen it just disappears.
• Rviz is just showing an empty grid. I can however add the RobotModel manually using the /lbr/robot_description as the description topic. I get a bunch of “No transform from link_0 to link_1” errors.
• I exited launch and checked for the gzserver. Output was empty so it should have been closed.
• I re-ran the launch and it unfortunately repeats the same behavior.

Update: I manged to launch it the way you described it using a docker container. I guess there is some problem with my ros2-humble setup on my machine. Thanks for your help!

I’ll try this later today, as I currently don’t have access to a PC. Hopefully I can replicate the issue and find a fix. Thank you for sharing

• Right now Im trying with the sim:=true, but the same occurs even with sim:=false.
• Yes I have replaced user with my username !
• please find below the entire terminal output with the command as mentioned by you with | grep ERROR and sim:=true.

And this is how Rviz windows opens: even if the world frame or lbr_link_0 is selected …
