Navfn Planner

The NavfnPlanner is a global planner plugin for the Nav2 Planner server. It implements the Navigation Function planner with either A* or Dij. expansions. It is largely equivalent to its counterpart in ROS 1 Navigation. The Navfn planner assumes a circular robot (or a robot that can be approximated as circular for the purposes of global path planning) and operates on a weighted costmap.

The global_planner package from ROS (1) is a refactor on NavFn to make it more easily understandable, but it lacks in run-time performance and introduces suboptimal behaviors. As NavFn has been extremely stable for about 10 years at the time of porting, the maintainers felt no compelling reason to port over another, largely equivalent (but poorer functioning) planner.

See its Configuration Guide Page for additional parameter descriptions.

Navfn Planner

The NavfnPlanner is a planning module that implements the nav2_tasks::ComputePathToPose interface.

A planning module implementing the nav2_tasks::ComputePathToPose interface is responsible for generating a feasible path given start and end robot poses. It provides the equivalent functionality to a GlobalPlanner in ROS1 MoveBase.

Status

Currently, NavfnPlanner’s core algorithm is a direct port from the ROS1 MoveBase Navfn planner. The Navfn planning algorithm is based on the Global Dynamic Window Approach.

Characteristics

In Dijkstra mode (use_astar = false) Dijkstra’s search algorithm is guaranteed to find the shortest path under any condition. In A* mode (use_astar = true) A*’s search algorithm is not guaranteed to find the shortest path, however it uses a heuristic to expand the potential field towards the goal.

The Navfn planner assumes a circular robot and operates on a costmap.

Task Interface

The Navigation System is composed of three tasks: NavigateToPose, ComputePathToPose and FollowPathToPose.

The DijkstraPlanner implements the Task Server interface for ComputePathToPose, specifically derives from nav2_tasks::ComputePathToPoseTaskServer. The client to DijkstraPlanner is ‘NavigateToPoseTask’, which periodically sends requests to the path planner.

Next Steps

  • Refactor Navfn. Currently difficult to modify/extend. Issue #244
  • Implement additional planners based on optimal control, potential field or other graph search algorithms that require transformation of the world model to other representations (topological, tree map, etc.) to confirm sufficient generalization. Issue #225
  • Implement planners for non-holonomic robots. Issue #225
