I'm trying to launch the file nao_control_trajectory.launch to load the robot's drivers. However, when executing (roslaunch nao_control_trajectory.launch), the process is stopped by the following warning:

[INFO] [1561388368.604146]: Spawner Controller: Waiting for service controller_manager / load_controller   
[WARN] [1561388398.884242]: Controller Spawner could not find the expected controller_manager ROS interface.   
[nao_trajectory_controller-2] process has finished cleanly

Does anyone know why this happens ? Thank you.
