Installation and Documentation
Install the following packages first:
$ sudo apt install libeigen3-dev python3wstool
$ sudo apt install ros-noetic-cmake-modules ros-noetic-velodyne-gazebo-plugins ros-noetic-ompl ros-noetic-move-base ros-noetic-navfn ros-noetic-dwa-local-planner ros-noetic-costmap-2d ros-noetic-teb-local-planner ros-noetic-robot-self-filter ros-noetic-pointcloud-to-laserscan ros-noetic-ros-numpy
$ sudo apt install ros-noetic-octomap-ros ros-noetic-octomap-server ros-noetic-pcl-ros ros-noetic-pcl-conversions ros-noetic-grid-map-costmap-2d ros-noetic-grid-map-ros ros-noetic-map-server ros-noetic-global-planner ros-noetic-grid-map-filters ros-noetic-grid-map-visualization
Then follow the instructions here to set up the simulation. Then, to build the planner:
$ catkin build smb_path_planner
Additional documentation on move_base
can be found here, while for the local planner, refer to the TEB Local Planner instructions here. Finally, the documentation about costmap_2d
is available here.
The smb_path_planner
package is composed by these packages:
-
smb_ompl_planner
: global planner formove_base
based on the OMPL library for motion planning; -
smb_navigation
: package containing utilities, configurations and launch files for the planning withmove_base
; -
smb_navigation_rviz
: package containing the RViz plugin to put a goal for the planner easily; -
traversability_layer
: customcostmap_2d
implementation to incorporate traversability maps.
This tool can be used to set the goals for the path planner.
Make sure all the packages have built successfully. As a sanity check, re-source your workspace ($ source ~/catkin_ws/devel/setup.bash
) and start up RViz ($ rviz
). In RViz, select Panels -> Add New Panel
and select Planning Panel
under smb_navigation_rviz
.
Next, under Displays
, add an InteractiveMarkers
display with the topic /planning_markers/update
. You should be able to see the interactive markers and the planning panel.
