Hi,

I've problems to launch pr2_empty_world.launch.This is a snippet of my error warnings:

[INFO] [1529084062.494837, 0.000000]: Calling service /gazebo/spawn_urdf_model

It seems to do something with the spawn_urdf_model and the following not recognized topics. Afterwards there comes Internal error messages... There's also this warning:

[ WARN] [1529084065.108074492]: The <focal_length>[320.000105] you have provided for camera_
[l_forearm_cam_sensor] is inconsistent with specified image_width [640] and HFOV [1.570800].   Please double check to see that focal_length = width_ / (2.0 * tan(HFOV/2.0)), the explected focal_lengtth value is [319.998825], please update your camera_ model description accordingly.

And a bit later:

Aborted (core dumped)
[WARN] [1529084065.931932, 0.000000]: Spawner couldn't reach pr2_controller_manager to take down controllers.

Have someone an idea what it might be? I'm using ROS kinetic on ubuntu 16.04. I have the intel hd graphics 520 onboard graphic card... Thanks in advance.

Thanks a lot!

Did you installed ubuntu additionally to windows?Does it work well parallel?

Yes, I did. I managed it with Xserver, seems to be stable.It seems more complicated to me to change to ubuntu...
