Hello,

I'm trying to launch view_demo.launch, but the rviz is empty and I get an warning: [ WARN] [1683803150.779816100]: The root link base_link has an inertia specified in the URDF, but KDL does not support a root link with an inertia. As a workaround, you can add an extra dummy link to your URDF.

For view_arm.lauch: [ WARN] [1683803542.847620400]: link 'bottom_link' material 'Brown' undefined. [ WARN] [1683803542.852397200]: link 'bottom_link' material 'Brown' undefined. [ERROR] [1683803542.853472300]: Geometry tag contains no child element.

As a workaround, you can add an extra dummy link to your URDF.

For both files in rviz error displays: obraz

Okay, it's just sufficient to go Add -> RobotModel and it shows.
