I'm trying to launch the controllers of a robot. When I run the file responsible for the launch of the drivers I get the following warning and I can not load the drivers:

[INFO] [1561569079.714364]: Controller Spawner: Waiting for service controller_manager/load_controller
[WARN] [1561569110.006476]: Controller Spawner couldn't find the expected controller_manager ROS interface.

I have also tried to launch the controllers with gazebo, but I get the same error. Does anyone know why this happens?
