getCostmapMaxExtent()

double nav2_regulated_pure_pursuit_controller::PathHandler::getCostmapMaxExtent ( ) const

protected

Get the greatest extent of the costmap in meters from the center.

Returns

max of distance from center in meters to edge of costmap

transformGlobalPlan()

nav_msgs::msg::Path nav2_regulated_pure_pursuit_controller::PathHandler::transformGlobalPlan	(	const geometry_msgs::msg::PoseStamped &	pose,
		double	max_robot_pose_search_dist,
		bool	reject_unit_path = false
	)

Transforms global plan into same frame as pose and clips poses ineligible for lookaheadPoint Points ineligible to be selected as a lookahead point if they are any of the following:

• Outside the local_costmap (collision avoidance cannot be assured)

  Parameters

  pose	pose to transform
  max_robot_pose_search_dist	Distance to search for matching nearest path point
  reject_unit_path	If true, fail if path has only one pose

  Returns

  Path in new frame
