7.3.5 导航之目标点与路径规划

目标点相关消息是:move_base_msgs/MoveBaseActionGoal，调用rosmsg info move_base_msgs/MoveBaseActionGoal显示消息内容如下:

std_msgs/Header header
  uint32 seq
  time stamp
  string frame_id
actionlib_msgs/GoalID goal_id
  time stamp
  string id
move_base_msgs/MoveBaseGoal goal
  geometry_msgs/PoseStamped target_pose
    std_msgs/Header header
      uint32 seq
      time stamp
      string frame_id
    geometry_msgs/Pose pose #目标点位姿
      geometry_msgs/Point position
        float64 x
        float64 y
        float64 z
      geometry_msgs/Quaternion orientation
        float64 x
        float64 y
        float64 z
        float64 w

路径规划相关消息是:nav_msgs/Path，调用rosmsg info nav_msgs/Path显示消息内容如下:

std_msgs/Header header
  uint32 seq
  time stamp
  string frame_id
geometry_msgs/PoseStamped[] poses #由一系列点组成的数组
  std_msgs/Header header
    uint32 seq
    time stamp
    string frame_id
  geometry_msgs/Pose pose
    geometry_msgs/Point position
      float64 x
      float64 y
      float64 z
    geometry_msgs/Quaternion orientation
      float64 x
      float64 y
      float64 z
      float64 w
