Charuco and chessboard patterns not loading in calibration_studio

[brunofavs]

Hey,

Whenever I try to launch either the calibration_studio.world or the calibration_studio_with_chessboard.world

roslaunch rrbot_gazebo gazebo.launch (charucos)

or

roslaunch rrcbot_gazebo gazebo.launch (chessboard)

I'm getting the following errors :

And no pattern is loaded in the world :

I wasn't familiar with how URI's worked before so I was studying a bit and found this :

https://github.com/lardemua/atom/blob/64465f7994f4e2c12cd0dd684df35a8b7d73299a/atom_core/src/atom_core/config_io.py#L155-L176

And I'm confused as there is no "model" URI scheme defined anywhere.

I checked and I have the necessary files in my local repo

But I cannot get it to load.

However it's funny because when I bring up the robot both the robot and pattern show on rviz however just the model shows on gazebo.

This truly feels like a newbie issue tbh.

Hello @brunofavs!

Yes this is a newbie issue :) But to be fair to you, I quickly searched through the documentation and did not find anything in there on how to solve this.

Gazebo has a property called GAZEBO_MODEL_PATH in which you define the models that gazebo can load. Since you did not update it to have atom_worlds/pattern/models, Gazebo searches for it and does not find it.

To add it, add this line to your .bashrc or .zshrc:

export GAZEBO_MODEL_PATH="`rospack find atom_worlds`/pattern/models:${GAZEBO_MODEL_PATH}"

This will update the model path to have the models on atom_worlds.

Another thing, very nice Issue construction, with a lot of details. Just one caveat, on your error messages, please copy and paste them instead of adding a print screen. Having it in text makes it easy for other people to search your issue on the web.

This information used to be in the installation section of each robotic system, but its not in atom examples.

@brunofavs , please create an issue to add it to the documentation?

and also easier to read. Not everyone likes a dark background, and has your preference for font size ...

Hey @miguelriemoliveira @manuelgitgomes Thank you both for the help, I added

To add it, add this line to your .bashrc or .zshrc: export GAZEBO_MODEL_PATH="rospack find atom_worlds/pattern/models:${GAZEBO_MODEL_PATH}"

And it worked right away :)

I do remember now having these issues back in @automec too with the traffic signals.

Thanks also for the feedback regarding the issue construction, I see now why pasting prints of error messages is undesirable.

I will do a follow-up issue soon on the documentation.
