Launch controllers of a robot
I'm trying to launch the file naocontroltrajectory.launch to load the robot's drivers. However, when executing (roslaunch naocontroltrajectory.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.
