3. Résumé des services

2.1 Pose du robot nav_msgs/Odometry

Le châssis pousse périodiquement la pose courante.

{
  "pose": { "pose": {
    "position": {"x": 1.23, "y": 4.56, "z": 0.0},
    "orientation": {"x": 0, "y": 0, "z": 0.5, "w": 0.866}
  }}
}

2.2 Chemin global nav_msgs/Path

Envoyé ~5 s après le début de la navigation, 5 fois au total (~30 s).

{ "poses": [
  {"pose":{"position":{"x":0,"y":0,"z":0}}},
  {"pose":{"position":{"x":1,"y":2,"z":0}}}
]}

2.3 Liste des cartes kitty_runtime_manager/MapList

Renvoie toutes les cartes et leurs points de passage enregistrés après abonnement.

{ "maps": [
  {"map_name":"Lobby","map_path":"/maps/floor1",
   "goals":[
     {"name":"Reception","x":1.0,"y":2.0,"theta":0.5},
     {"name":"Elevator","x":3.0,"y":4.0,"theta":1.2}
   ]}
]}

2.4 État de navigation std_msgs/Float64MultiArray

{ "success": true, "message": "Docking started" }

3.6 Naviguer vers une pose nav_msgs/GetPlan

Service :/navigate_to_pose

{
  "goal": { "pose": { "position": { "x": 1.0, "y": 2.0, "z": 0.0 } } }
}

{ "plan": { "poses": [
  {"pose":{"position":{"x":0,"y":0,"z":0}}},
  {"pose":{"position":{"x":1,"y":2,"z":0}}}
]}}

3.7 Annuler la navigation nav_msgs/GetPlan

Service :/navigate_to_pose（(même service que la navigation, utilisez des coordonnées spéciales pour annuler)）

{
  "goal": { "pose": { "position": { "x": 999999, "y": 888888, "z": 0 } } }
}

{ "plan": { "poses": [] } }
