Hi! I am trying to run a custom **humanoid robot (foo) in Gazebo**. I have the urdf running correctly (in Rviz and Gazebo the robot spawns without problems. However i am not able of doing the correct set up of the control in Gazebo. **When the robot spawns it falls to the ground**. The only warning i have is the following: [WARN] Controller Spawner couldn't find the expected controller_manager ROS interface. So i suppose the problem is that the **control is not loaded**. I have searched for similar problems, and i have made sure that the plugin is correctly configured. The output of **rosservice list | grep controller_manager** is /foo/controller_manager/list_controllers /foo/controller_manager/load_controller /foo/controller_manager/reload_controller_libraries /foo/controller_manager/switch_controller /foo/controller_manager/unload_controller I have also checked the **namespaces**, but i can not see anything wrong. I have the following code for the spawn of the robot: The following for the control: I think all the stuff is loaded in the **foo namespace**. If any of you have any clue about why this could be happenning, you will be welcome. Thank you in advance!
