The autoware_freespace_planner

freespace_planner_node

freespace_planner_node is a global path planner node that plans trajectory in the space having static/dynamic obstacles. This node is currently based on Hybrid A* search algorithm in freespace_planning_algorithms package. Other algorithms such as rrt* will be also added and selectable in the future.

Note Due to the constraint of trajectory following, the output trajectory will be split to include only the single direction path. In other words, the output trajectory doesn’t include both forward and backward trajectories at once.

Input topics

Name Type Description
~input/route autoware_planning_msgs::Route route and goal pose
~input/occupancy_grid nav_msgs::OccupancyGrid costmap, for drivable areas
~input/odometry nav_msgs::Odometry vehicle velocity, for checking whether vehicle is stopped
~input/scenario tier4_planning_msgs::Scenario scenarios to be activated, for node activation

Output topics

Name Type Description
~output/trajectory autoware_planning_msgs::Trajectory trajectory to be followed
is_completed bool (implemented as rosparam) whether all split trajectory are published

Output TFs

None

How to launch

  1. Write your remapping info in freespace_planner.launch or add args when executing roslaunch
  2. roslaunch freespace_planner freespace_planner.launch

The autoware_freespace_planner

freespace_planner_node

freespace_planner_node is a global path planner node that plans trajectory in the space having static/dynamic obstacles. This node is currently based on Hybrid A* search algorithm in freespace_planning_algorithms package. Other algorithms such as rrt* will be also added and selectable in the future.

Note Due to the constraint of trajectory following, the output trajectory will be split to include only the single direction path. In other words, the output trajectory doesn’t include both forward and backward trajectories at once.

Input topics

Name Type Description
~input/route autoware_planning_msgs::Route route and goal pose
~input/occupancy_grid nav_msgs::OccupancyGrid costmap, for drivable areas
~input/odometry nav_msgs::Odometry vehicle velocity, for checking whether vehicle is stopped
~input/scenario tier4_planning_msgs::Scenario scenarios to be activated, for node activation

Output topics

Name Type Description
~output/trajectory autoware_planning_msgs::Trajectory trajectory to be followed
is_completed bool (implemented as rosparam) whether all split trajectory are published

Output TFs

None

How to launch

  1. Write your remapping info in freespace_planner.launch or add args when executing roslaunch
  2. roslaunch freespace_planner freespace_planner.launch

Parameters

{{json_to_markdown(“planning/autoware_freespace_planner/schema/freespace_planner.schema.json”)}}

The autoware_freespace_planner

freespace_planner_node

freespace_planner_node is a global path planner node that plans trajectory in the space having static/dynamic obstacles. This node is currently based on Hybrid A* search algorithm in freespace_planning_algorithms package. Other algorithms such as rrt* will be also added and selectable in the future.

Note Due to the constraint of trajectory following, the output trajectory will be split to include only the single direction path. In other words, the output trajectory doesn’t include both forward and backward trajectories at once.

Input topics

Name Type Description
~input/route autoware_planning_msgs::Route route and goal pose
~input/occupancy_grid nav_msgs::OccupancyGrid costmap, for drivable areas
~input/odometry nav_msgs::Odometry vehicle velocity, for checking whether vehicle is stopped
~input/scenario tier4_planning_msgs::Scenario scenarios to be activated, for node activation

Output topics

Name Type Description
~output/trajectory autoware_planning_msgs::Trajectory trajectory to be followed
is_completed bool (implemented as rosparam) whether all split trajectory are published

Output TFs

None

How to launch

  1. Write your remapping info in freespace_planner.launch or add args when executing roslaunch
  2. roslaunch freespace_planner freespace_planner.launch

The autoware_freespace_planner

freespace_planner_node

freespace_planner_node is a global path planner node that plans trajectory in the space having static/dynamic obstacles. This node is currently based on Hybrid A* search algorithm in freespace_planning_algorithms package. Other algorithms such as rrt* will be also added and selectable in the future.

Note Due to the constraint of trajectory following, the output trajectory will be split to include only the single direction path. In other words, the output trajectory doesn’t include both forward and backward trajectories at once.

~input/route autoware_planning_msgs::Route route and goal pose
~input/occupancy_grid nav_msgs::OccupancyGrid costmap, for drivable areas
~input/odometry nav_msgs::Odometry vehicle velocity, for checking whether vehicle is stopped
~input/scenario tier4_planning_msgs::Scenario scenarios to be activated, for node activation

Output topics

Name Type Description
~output/trajectory autoware_planning_msgs::Trajectory trajectory to be followed
is_completed bool (implemented as rosparam) whether all split trajectory are published

Output TFs

None

How to launch

  1. Write your remapping info in freespace_planner.launch or add args when executing roslaunch

The autoware_freespace_planner

freespace_planner_node

freespace_planner_node is a global path planner node that plans trajectory in the space having static/dynamic obstacles. This node is currently based on Hybrid A* search algorithm in freespace_planning_algorithms package. Other algorithms such as rrt* will be also added and selectable in the future.

Note Due to the constraint of trajectory following, the output trajectory will be split to include only the single direction path. In other words, the output trajectory doesn’t include both forward and backward trajectories at once.

Input topics

Name Type Description
~input/route autoware_planning_msgs::Route route and goal pose
~input/occupancy_grid nav_msgs::OccupancyGrid costmap, for drivable areas
~input/odometry nav_msgs::Odometry vehicle velocity, for checking whether vehicle is stopped
~input/scenario tier4_planning_msgs::Scenario scenarios to be activated, for node activation

Output topics

Name Type Description
~output/trajectory autoware_planning_msgs::Trajectory trajectory to be followed
is_completed bool (implemented as rosparam) whether all split trajectory are published

Output TFs

None

How to launch

  1. Write your remapping info in freespace_planner.launch or add args when executing roslaunch
  2. roslaunch freespace_planner freespace_planner.launch

Parameters

{{json_to_markdown(“planning/autoware_freespace_planner/schema/freespace_planner.schema.json”)}}

The autoware_freespace_planner

freespace_planner_node

freespace_planner_node is a global path planner node that plans trajectory in the space having static/dynamic obstacles. This node is currently based on Hybrid A* search algorithm in freespace_planning_algorithms package. Other algorithms such as rrt* will be also added and selectable in the future.

Note Due to the constraint of trajectory following, the output trajectory will be split to include only the single direction path. In other words, the output trajectory doesn’t include both forward and backward trajectories at once.

Input topics

Name Type Description
~input/route autoware_planning_msgs::Route route and goal pose
~input/occupancy_grid nav_msgs::OccupancyGrid costmap, for drivable areas
~input/odometry nav_msgs::Odometry vehicle velocity, for checking whether vehicle is stopped
~input/scenario tier4_planning_msgs::Scenario scenarios to be activated, for node activation

Output topics

Name Type Description
~output/trajectory autoware_planning_msgs::Trajectory trajectory to be followed
is_completed bool (implemented as rosparam) whether all split trajectory are published

Output TFs

None

How to launch

  1. Write your remapping info in freespace_planner.launch or add args when executing roslaunch
  2. roslaunch freespace_planner freespace_planner.launch

Parameters
