LPAStarPlanner

Struct LPAStarPlanner 

Source
pub struct LPAStarPlanner { /* private fields */ }
Expand description

Lifelong Planning A* planner.

Keeps g and rhs tables across calls so that incremental replanning (via plan_with_cost_change) only processes nodes affected by edge-cost changes.

Implementations§

Source§

impl LPAStarPlanner

Source

pub fn new(ox: &[f64], oy: &[f64], config: LPAStarConfig) -> Self

Create a planner from raw obstacle x/y slices; panics on invalid input.

Source

pub fn try_new( ox: &[f64], oy: &[f64], config: LPAStarConfig, ) -> RoboticsResult<Self>

Create a validated planner from raw obstacle x/y slices.

Source

pub fn from_obstacle_points( obstacles: &Obstacles, config: LPAStarConfig, ) -> RoboticsResult<Self>

Create a validated planner from typed obstacle points.

Source

pub fn plan(&self, start: Point2D, goal: Point2D) -> RoboticsResult<Path2D>

Plan a path from start to goal.

Source

pub fn plan_with_cost_change( &mut self, start: Point2D, goal: Point2D, changed_edges: &[EdgeChange], ) -> RoboticsResult<Path2D>

Replan after edge-cost changes without restarting from scratch.

changed_edges lists cells whose traversal cost has changed. The planner updates only the affected vertices and runs ComputeShortestPath to convergence.

Source

pub fn grid_map(&self) -> &GridMap

Reference to the internal grid map.
