```yaml controller_manager: ros__parameters: update_rate: 1000 use_sim_time: true joint_state_broadcaster: type: joint_state_broadcaster/JointStateBroadcaster ackermann_drive: type: ackermann_steering_controller/AckermannSteeringController ackermann_drive: ros__parameters: publish_rate: 500.0 front_wheels_names: [left_wheel_steering_joint, right_wheel_steering_joint,right_back_wheel_steering_joint,left_back_wheel_steering_joint] rear_wheels_names: [left_wheel_joint,right_wheel_joint,wheel_back_right_joint, wheel_back_left_joint] #left_wheel_names: ["left_wheel_joint"] #right_wheel_names: ["right_wheel_joint"] #left_steering_name: ["left_wheel_steering_joint"] #right_steering_name:...

and here my ros2_control config gazebo_ros2_control/GazeboSystem -10 10 -10 10 -10 10 -10 10 robot_description robot_state_publisher /ackermann_drive/odometry:=odom /ackermann_drive/tf_odometry:=tf $(find my_bot)/config/my_controllers.yaml Gazebo/Blue Gazebo/White Gazebo/White Gazebo/White Gazebo/White

[my_bot.zip](https://github.com/ros-controls/ros2_controllers/files/13540288/my_bot.zip) This zip content my package To launch the simulation , ros2 launch my_bot launch_sim.launch.py
