THE PROBLEM
This paper focuses on Navigation & LocomotionPath planningChoosing a path from start to goal.. This paper solves the problem of routing a Core ConceptsRobotA physical system with sensors and actuators that can observe the world and take actions. to visit moving targets while avoiding moving obstacles within time windows.

LIMITATIONS
The main limitation to check is whether the claimed behavior holds outside the paper's reported setup. That means testing across different Core ConceptsRobotA physical system with sensors and actuators that can observe the world and take actions. embodiments, scenes, objects, and data distributions.
WHAT COMES NEXT
The practical next step is independent reproduction with clear baselines, ablations, and stress tests. For a developer, the useful follow-up is to map the paper's Navigation & LocomotionPath planningChoosing a path from start to goal. assumptions onto a concrete Core ConceptsRobotA physical system with sensors and actuators that can observe the world and take actions. stack, then test the smallest version of the method that could run end to end.
