PS: much better instructions to execute it are required. Even more important when it targets to novel students.

There are missing models in the .gazebo/models directory. Do you have the lastest f1 model installed? Works fine for me. It's a little heavy to load because the model is pretty big, but works fine for me. Make sure you have the the f1 model in the lastest version.

[varhub]

Sorry bro, You must known better than any other that missing models are recognized as:

[Wrn] [ModelDatabase.cc:334] Getting models from[http://gazebosim.org/models/]. This may take a few seconds.

And eventually, after database timeout, hint if finally presented:

Copy all the models from JdeRobot to .gazebo/models and try again. El 27/03/2016 17:32, "Victor Arribas" notifications@github.com escribió:

Also, the F1 model version that comes with the pacakage isn't the last version. So, the fixed model is in github and not in the rc6 package yet. That model was giving that problem because it was trying to load the hokuyo laser mesh from the turtlebot model and not from the f1 model. So if you download the F1 model from github and copy it to .gazebo/models it should work.

Working except this:

[Err] [Material.cc:93] Unable to find texture[Color_006.jpg] in path[/home/varribas/curso_ws/.gazebo/models/pista/meshes]

Noticed that lateral protections are red and sometimes black-gray. Is this the expected behavior?

[fqez]

The black-gray parts are a lighting issue. In the 3D modeling software (sketchup/blender) it is all red, but the ambient factor of the texture is not good. I can solve it if it bothers you so much.

[varhub]

Its not a problem except for color filter ;) Let it there for make it a little harder.
