I am a beginner in ROS and RViz I would like to get Kinect Module work with UR5 Simulation.

Right now I installed UR5 Library from Universal Robot

After that I installed Openni Kinect Kinetic version on my Ubuntu 16.04. I run these commands:

roslaunch ur_gazebo ur5.launch

And add my Kinect Camera as it is told in the tutorials and my Model.sdf file looks like this:

<?xml version='1.0'?>
<sdf version='1.6'>
  <model name='camera'>
    <link name='link'>

</sdf>

I run these two command for Rviz simulation as it is in the Universal Robot Git.

roslaunch ur5_moveit_config ur5_moveit_planning_execution.launch sim:=true
roslaunch ur5_moveit_config moveit_rviz.launch config:=true

But cannot set Camera_link which is my Camera frame inside this:

phot of Rviz:

But I cannot see anything as a sensor data. And even there is publishers in rostopic nothing published on them with this error

rostopic echo /camera/depth/image_raw
WARNING: no messages received and simulated time is active.
Is /clock being published?

please help :D

Comment by Meric on 2019-03-21:
The main problem might be Fixed Frame in my sdf file doesnt exist on Rviz

Comment by Meric on 2019-03-21:
I made my Camera Model.sdf to World as URF Rviz simulation frame, Nothing changed, doesnt see anything published

Comment by Meric on 2019-03-21:
Also Error Log when I insert the Kinect Camera

gzserver: /build/ogre-1.9-mqY1wq/ogre-1.9-1.9.0+dfsg1/OgreMain/src/OgreRenderSystem.cpp:546: virtual void Ogre::RenderSystem::setDepthBufferFor(Ogre::RenderTarget*): Assertion `bAttached && "A new DepthBuffer for a RenderTarget was created, but after creation" "it says it's incompatible with that RT"' failed.

IT Has nothing to do with Fixed Frame, The Model file can have standalone frame name which should be same with Rviz frame.

Ok After I upgraded to the Gazebo 7.14 Which cost me like nearly a DAY, the problem seem to fixed. I am not sure if is fully fixed but I can see a gray scale image and I can rostopic echo the publishers and some values of arrays comes in.

I wish some one could find this answer usefull. Thanks
