What problem does it solve?

SMAC Hybrid-A* planner provides non-holonomic, kinematically feasible path planning for ROS 2 Nav2 by extending A* into SE(2) with motion primitives and a closed-form analytic expansion when possible.

Core Features & Use Cases

  • Supports planning in SE(2) using discretized headings and motion primitives (DUBIN/REEDS_SHEPP) to produce executable paths for differential drive and Ackermann robots.
  • Exposes tunable parameters such as minimum_turning_radius, motion_model_for_search, angle_quantization_bins, analytic_expansion_ratio, and lookup_table_size to balance speed and path quality.
  • Useful for docking, parking, and navigating tight corridors where non-holonomic constraints are critical for safe, feasible trajectories.

Quick Start

Configure the planner in Nav2 with your robot's parameters and run a planning request on a sample map.
