Hi, I am running gzserver and gzclient separately and when I have an SDF issue, it's not displaying in gzserver but in gzclient, even without --verbose !

Hi, I am running gzserver and gzclient separately and when I have an SDF issue, it's not displaying in gzserver but in gzclient, even without --verbose ! Eg : Warning [parser.cc:713] XML Element[collision], child of element[visual] not defined in SDF. Ignoring[collision]. You may have an incorrect SDF file, or an sdformat version that doesn't support this element.

I just changed my wheel mass from 0.1 to 1 and the model don't crash anymore. I just now have severe slip problems, but I guess the problem is not related. I'll try messing with friction parameters.

One link is 10 and the other one is 0.1 ? I'm gonna try setting my wheel to 1 instead

Hi there,

I'm trying to get a plugin to control wheel speed, but as soon a I apply joint::setForce() on a joint, with any value, it justs make my model crash after few iterations.

When I disable the plugin, my model seems to be stable. I can apply forces on the wheels joints inside gazebo.

But even inside gazebo, if I apply a the minimal velocity to the joints (0.001), my model starts dancing.

I don't know if both problems are related, but i thought it might help you figure out what is happening.

I think my inertia matrix are fine, when I print center of mass/inertia, it looks good.

Could it be because the link mass is under 1, which make the value in the inertia matrix very small.

Thanks,

Hi,

I'm trying to use a projector on a model and i need a connection to ROS.

I've tried to work with SDF and not URDF as most tutorials.

I took the gazebosrosprojector plugin from gazeborosplugin folder and tried to add it to my model.

My model is like

< model >

< link >
...
< /link >

< link >
...
< projector >
< /projector >
< /link >

< /model >

When I add the plugin inside the <projector>, it's not called (I've put some debug inside Load() )

When I add the plugin to the model, I don't get how to connect it to my projector, it is saying :
Unable to find value for key[projector]

I can make this error disappear by adding another < projector > field inside the plugin declaration but I can't see how to link it to my projector.

Any ideas?

Thank you,
