Hi all, how i have the model of a pan-tilt unit that i have wrote xml urdf file and imported in the parameter server, I'm able to see it in rviz but now I want to move it in function of the real position that I can read from the topic ptu/state that is in joint_state form.

I suppose that I need also the tf that robot_state_pubblisher can create but I don't know how to set it to read the correct topic because it create a tf topic but is void.

Thank you

yes, I merged all the joint_state messages of the various node into the input of the robot_state_pubblisher via remapping inside launch file

eg of the remap into launch file:

<node name="joint_state_publisher" pkg="joint_state_publisher" type="joint_state_publisher" >="" <rosparam="" param="source_list">[/ptu/state, joint_states, /motore_1_controller/joint_states, /motore_2_controller/joint_states, /motore_3_controller/joint_states, /motore_4_controller/joint_states]</rosparam> </node>
