Launch controllers of a robot
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.
Have you installed the below packages?
1) gazebo-ros-pkgs and gazebo-ros-control
2) ros-kinetic-ros-control and ros-kinetic-ros-controllers
3) ros-kinetic-gazebo-ros-control
