Hello,
when I run the launch file navigation_demo_sim.launch.py I can not navigate the rosbot in rviz2.
I get the following message in Rviz2:
The class required for this panel, ‘nav2_rviz_plugins/Navigation 2’, could not be loaded.
Error:
According to the loaded plugin descriptions the class nav2_rviz_plugins/Navigation 2 with base class type rviz_common::Panel does not exist. Declared types are rviz_visual_tools/RvizVisualToolsGui slam_toolbox::SlamToolboxPlugin
Hi Udo,
I did all the steps and there are some problems so please make sure you have installed all three rviz, gazebo and navigation2. Then you have to do all the steps from this readme from installation chapter. (remember that you have different workspace then it’s used in readme, so either remove the one from tutorial or remember to change ros2_workspace to rosbot_ws in all commands).
Hi Udo,
I’m sorry for late response. I checked and yes you are right I used rviz2 in this launch. It was installed automatically by this command rosdep install --from-paths src --ignore-src -r -y from readme. My version of rviz2:
This is RViz version Alpha (ROS 2.0).
Compiled against Qt version 5.12.8.
Compiled against OGRE version 1.12.1 (Rhagorthua)
