Hi! that's exactly my problem here. I'm also running ROS kinetic and gazebo 7. I've not been able to resolve it yet, but

Hello!

I've been recently playing with the official ROS simulated Pepper in Gazebo and I'm facing a little problem. When I launch the example (using roslaunch) and start the simulation, the robot starts falling very slowly ( here's a video showing the problem).

The only error trace that roslaunch shows is:

[ERROR] [1515588569.033999191]: GazeboRosDiffDrive Plugin missing <legacyMode>, defaults to true
This setting assumes you have a old package, where the right and left wheel are changed to fix a former code issue
To get rid of this error just set <legacyMode> to false if you just created a new package.
To fix an old package you have to exchange left wheel by the right wheel.
If you do not want to fix this issue in an old package or your z axis points down instead of the ROS standard defined in REP 103
just set <legacyMode> to true.

I'm working with ROS Kinetic and Gazebo 7.9.0. The model I'm using is the one included in the debian packages for ROS kinetic.

Am I doing something wrong? Or am I missing a package or something?

Thanks in advance.

Is there no solution then? Based on your link akhadke.

I will try that, thank you very much!

Hi, I'm facing the same problem.. Did you solve it? Thanks!

Yes, you have to set your texture options when you export your model. When you click "export" there is a menu in the lef

Hi Nate, thank you very much for your tips! Now I have a better result of the model. It's still dark if it's far away from the sun but it can be seen now clearly. The solution for me is: 1- Import the .dae file to Blender. 2- Export it again in .dae format from Blender (now it has <ambient>tags 3- Replace all <ambient>0 0 0 1</ambient> to <ambient>1 1 1 1</ambient>. I do that manual change because I don't know how to apply ambient values to the faces of my model yet. But it works! Thanks again!

No, I can't see that option. I tried to add the ambient tag to the grass texture but it doesn't seem to change either (not sure if I did properly tho). Should I export it to another format and then use another converter; like .skp --> .3ds --> .dae Thanks

I'm not sure if I can post external links, but here we are: https://www.dropbox.com/s/imurx0jh9urpxr0/circuit.zip?dl=0 Thanks!

Hi,

I have a problem with a collada (.dae) model and Gazebo. I've got a race circuit model made with sketchUp

and I've exported it to a collada format (.dae). The problem is: when I import that collada file to Gazebo it appears almost black, as you can see in this image:

You can see that the ground_plane model has proper lighting, unlike my model. I only can barely see the textures applied to the model if I get near to it (see the grass and the building):

I'm almost sure that the problems come with the textures and color applied to the model, but I've no clue how to solve this issue. I've tried to modify the sun parameters in Gazebo, I've also tried to invert all the faces just to make sure is not a normals inverted problem, I've created a world with no lights at all and included an scene tas, as this one:

<scene>
    <ambient>0.5 0.5 0.5 1.0</ambient>
    <shadows>0</shadows>
</scene>

But all of this ends the same, the model almost black. I've also try to uncheck "cast shadows" in the sun model. Also, when I include a point light the changes on the lighting are negligible. After some researching within this forum, I've reached no answer to my problem.

Do you know what is happening?

Thanks in advance!
