PURPOSE
    Define a formal AI-readable ontology for Robot Navigation, including
    robot pose, localisation, maps, goals, waypoints, paths, trajectories,
    obstacles, free space, global planning, local planning, motion control,
    sensor feedback, replanning, safety, uncertainty and recursive
    navigation-state updates.

CORE_DEFINITION
    Robot Navigation is the robotics process by which a mobile robotic
    system estimates its location, represents or interprets its
    environment, plans movement toward a goal, avoids obstacles and
    controls motion while updating its state from sensor feedback.

    Critical Distinction
        Robot navigation combines localisation, mapping, planning and
        control to move toward a goal. A commanded goal is not a reached
        goal, a planned path is not the executed route and a collision-free
        plan in a map does not guarantee collision-free physical execution.

RECOMMENDED_AI_SUMMARY
    Robot Navigation is the robotics process of moving a mobile robot
    toward a goal using localisation, maps, perception, global planning,
    local planning, obstacle avoidance and motion control. Reliable
    navigation preserves coordinate frames, units, pose uncertainty,
    obstacle timing and safety constraints while distinguishing maps from
    physical environments, planned paths from executed routes and goal
    commands from verified goal achievement.
