I am trying to follow '8. PR2 Navigation Stack Demo' in pr2_simulator/Tutorials/BasicPR2Controls.

After launching pr2 with rviz by typing

  • roslaunch ~/pr2_nav_tutorial.launch
  • roslaunch pr2_navigation_global rviz_move_base.launch

In 'move_base.rviz', I can see a (green) path is planned between the init and goal pos selected by me. But PR2 does not move to follow the path as described in the tutorial. The error messages from the command line are as follows:

Any idea to fix this problem?
