DAG-STL: A Hierarchical Framework for Zero-Shot Trajectory Planning under Signal Temporal Logic Specifications

The paper frames the work as planningControl & PlanningPlanningFiguring out what the robot should do before or during movement.. Start here because it defines what success means and which assumptions the rest of the method inherits.

This paper lets robots plan long-horizon tasks specified in natural logical constraints (e.g., 'visit region A, then B, while avoiding obstacles') without knowing the robotCore ConceptsRobotA physical system with sensors and actuators that can observe the world and take actions.'s dynamicsMovement, Mechanics & Robot BodyDynamicsThe study of motion including forces, torques, mass, and inertia. or trainingRobot LearningTrainingThe process of fitting a model using data or experience. on task-specific data.
