Disabling the head from tracking the executed trajectory of the arm

edit

I think there is no explicit ros parameter for disabling head tracking, but if you just set the parameter head_monitor_link to empty or delete it, moving the head should be disabled.

You have several ways to set the corresponding parameters. You can either build up your own launch file by copying and adjusting e.g. move_right_arm.launch or you can create your own launch file that might look like this:

<launch>
  <include file="$(find pr2_arm_navigation_actions/launch/move_right_arm.launch>
  <param name="/move_right_arm/head_monitor_link"
         type="str"
         value=""/>
</launch>

This exploits the evaluation order of launch files. Later parameter definitions can overwrite earlier ones.
