Hi everyone,  
I am simulating a UR3e in ros gazebo and i am trying to get the motor torques of all the joints. When I read out the effort values in the joint\_states topic they always remain 0.0, even when the robot is moving. How can I get the joint torques?  
Kind regards  
Dimitri

I think, ROS answers is the better place to ask this, as this is not containing anything robot- or driver-related.

Gazebo brings along an own simulated hardware interface and controller manager that runs the respective controllers.
