seems like the file urs_wearable/launch/world.launch is including itself and creating an infinite loop,

You should go to an ROS forum. Maybe they can guide you more. https://answers.ros.org/questions/

Hi Jeremy! Yesterday you gave the same answer. I didn't understand exactly what you said. The recursive call of the world.launch file is not shown in the code I posted. Can you be more precise?

[jge162]

The recursion error message you're seeing is being caused by a problem in your launch file. Specifically, it looks like there is an issue with the tag that is causing the launch file parser to enter into an infinite loop.

I suggest you to check if the package URSSimEnvironments is installed and the folder urs_wearable exists. Also to check if the world test.world exists in the path mentioned in the launch file.

[Jun-gil]

URSSimEnvitonmaents is a file I created. So I just converted it to a package. urs_wearable is a package in URSSimEnvitonmaents. The path of test.world is as follows.
urs_wearable/worlds/test.world

Are there any more things left to try?

[jge162]

I have no more ideas for you sorry. your issue has to be with files.

Make sure that the path to your world file is correct. In your message, you mention that the path to the world file is "urs_wearable/worlds/test.world". Verify that this path is correct, and that the file is located at the correct location in your filesystem.

Check if any of the parameter in the launch file is not defined properly

Check if the package URSSimEnvironments is built and sourced correctly.

You can also try to re-build your package using catkin_make command.

Please close. Repeat ticket. See original here #45397

I'm not familiar with how to use Git. I will use repeat tickets in the future.

No worries.
