Hi,

It appears that you haven't launched the rviz configuration associated with this particular tutorial but instead have the configuration associated with a previous tutorial.  Try the following command:

roslaunch pr2_arm_navigation_tutorials rviz_collision_tutorial_2.launch

and you should get the StateValidity topic and the ghosted robot.

Let me know if you have other questions.

-Gil

you.
