How to publish joint_states after configuring a robot with moveit

edit

Hi everyone,

I am using the hector quadrotor package and I have used moveit to plan path for it. I have configured the robot using moveit_setup assistant. I am visualizing it in rviz using the generated demo.launch file. However in rviz I can only see the planned path and the actual robot does not move. After I looked into several sources I found that the /joint_states topic is not updated as the results are updated via a fake trajectory controller. Can someone provide me a solution on how to update the joint_states topic?

P.N. - the quadrotor does not have any end_effector, thus I cannot set target pose.
