Describe the Bug
[webots_controller_TurtleBot3Burger-5] [ERROR] [1727690103.628136189] [controller_manager]: Could not initialize the controller named 'diffdrive_controller'
[webots_controller_TurtleBot3Burger-5] Exception thrown during init stage with message: Invalid value set during initialization for parameter 'left_wheel_names': Parameter 'left_wheel_names' cannot be empty.
Trying the webots_ros2_turtlebot package but fails on the 'diffdrive_controller' node. This makes me unable to use the teleop nodes. I know that it uses "/opt/ros/jazzy/share/webots_ros2_turtlebot/resource/ros2control.yml" as the --params-file, however, that seems to be complete.
...
diffdrive_controller:
ros__parameters:
left_wheel_names: ["left wheel motor"]
right_wheel_names: ["right wheel motor"]
...
Steps to Reproduce
- Install necessary packages for webots_ros2_turtlebot (webots, ros2, ros-jazzy-ros2-turtle
$ ros2 launch webots_ros2_turtlebot robot_launch.py- See terminal for the error.
Expected behavior
Being able to drive the robot with teleop nodes.

The wifi card of my laptop is not working, maybe that is the problem? The webots_controller python script uses ipc by default but maybe using tcp would be better?
