hey ,i am trying to add ros2_control for my proejct so i thought first let me go through the docs.
so i installed all thing but after runing “ros2 launch ros2_control_demo_example_1 rrbot.launch.py” and then when i ran “ros2 control list_hardware_interfaces” and “ros2 control list_controllers” i did not get the expected outcome as it it says in the docs
iget some thing like this
ros2 control list_hardware_interfaces
[INFO] [1738429606.718925216] [_ros2cli_84682]: waiting for service /controller_manager/list_hardware_interfaces to become available…
