  "packages": [
    "ROS 2 Jazzy",
    "ros2_control, ros2_controllers and ros2_control_demos pinned source"
  ],
  "display": "Launch examples require their matching description, controller YAML and hardware plugins. Default mock/Gazebo configurations differ; inspect launch arguments before hardware use.",

## Invocation

```json
{
  "entrypoint": "ros2 launch ros2_control_demo_example_9 rrbot_gazebo.launch.py",
  "notes": "Launch examples require their matching description, controller YAML and hardware plugins. Default mock/Gazebo configurations differ; inspect launch arguments before hardware use. No Hub preparation adapter or measured runtime success is claimed."
