Navigating the Clutter: Waypoint-Based Bi-Level Planning for Multi-Robot Systems

The paper frames the work as motion planningControl & PlanningMotion planningFinding a path or motion that gets the robot from start to goal.. Start here because it defines what success means and which assumptions the rest of the method inherits.
