Hi @vkuehn,
this is very good, the script runs without producing any output message.
Whats important is that your script is being executed without any error messages. The error message that was appearing before has gone!
If you want to confirm that the node is running you can go to a second terminal and type:
ros2 node list
It should show you the name of the node.
Or you could type ros2 action list and yous should see /joint_trajectory_controller/follow_joint_trajectory
under the list of action names.
I think this issue is solved.

Roberto
Hi @rzegers ,
As of your statement I have restarted all
terminal 1 ros2 launch my_box_bot_gazebo start_world.launch.py
terminal 2 ros2 launch my_box_bot_gazebo spawn_robot_ros2_control_velocity.launch.xml
terminal 3 ros2 run my_box_bot_gazebo move_laser.py 0.0
now it shows
[INFO] [1676034335.147019755] [move_laser_actionclient]: Goal accepted :)
[INFO] [1676034335.966443082] [move_laser_actionclient]: Result: control_msgs.action.FollowJointTrajectory_Result(error_code=0, error_string='')
terminal 4 ros2 node list
shows
/box_bot_joint_state
/controller_manager
/differential_drive_controller/gazebo
/gazebo_ros2_control/joint_state_broadcaster
/joint_trajectory_controller
/my_robot_state_publisher_node
/rviz_node
/transform_listener_impl_55cbd69c1b60
/velocity_controller
And the Robot still does not move the laser up and down
which would be expected right ?
Cheers,

Hi @rzegers
ups my fault. It works with
ros2 run my_box_bot_gazebo move_laser.py -20.0
Thank a lot for your passion on the topic
Solved, have a nice Weekend !
Cheers,

Hi @vkuehn,

Nice weekend too!
