General Support

Hi,
When launching my demo_gazebo.launch file generated by the MSA after having added the controllers.yaml file I get the error “Action client not connected” After waiting for a while rostopic list does not show any topics related to the controllers as shown in ROS Control 101 Tutorial. Does anybody know what is going on? @staff
