<<PackageHeader(pr2_navigation_slam)>>
<<TOC(4)>>

== Overview ==
This package contains configuration files for the [[move_base]] and [[gmapping]] nodes meant to be run in an application that requires SLAM-based global navigation. This package also includes launch files that bring up [[rviz]] and [[nav_view]] with global navigation specific configuration options.

== Applications ==
 * '''`rviz/rviz_move_base_slam.launch`''': Starts [[rviz]] with a SLAM friendly navigation setup.
 * '''`nav_view/nav_view_move_base_slam.launch`''': Starts [[nav_view]] with a SLAM friendly navigation setup.

== Building Blocks ==
 * '''`move_base.xml`''': Holds a PR2 specific configuration of the [[move_base]] node designed fow navigation with a SLAM system. Should be run in conjunction with [[gmapping]] or another SLAM system with a similar interface.
 * '''`slam_gmapping.xml`''': Holds a PR2 specific configuration of the [[gmapping]] node. Designed to be included by applications that wish to run [[gmapping]] on the PR2.

== Configuration Files ==
 * '''`config/base_local_planner_params.yaml`''': Holds parameters for the [[base_local_planner]] specific to SLAM-based navigation on the PR2.
 * '''`config/global_costmap_params.yaml`''': Holds parameters for the global [[costmap_2d | costmap]] used in thee `move_base.xml` configuration file. This is the costmap used by the [[navfn]] planner, and in this case, receives periodic updates from a SLAM system such as [[gmapping]].
 * '''`config/local_costmap_params.yaml`''': Holds parameters for the local [[costmap_2d | costmap]] used in the `move_base.xml` configuration file. This is the costmap used by the [[base_local_planner]] planner, which operates in an odometric frame.
 * '''`config/move_base_params.yaml`''': Holds SLAM-based navigation specific parameters for the [[move_base]] node.
