如何在不使用nav2_amcl节点的情况下实现单点导航？

孤独的幸存者

我自己写了一个定位的节点可以发布map->odom的tf转换。
我的机器人上面有里程计节点提供odom->base_link的tf转换。
因为我是直接使用平面图作为map的，不需要LIDAR来进行建图和定位，但是我不知道如何配置navigation.yaml.

我尝试调用nav2_bringup里的navigation.launch.py且使用了下面这个yaml文件：

# GPS WPF CHANGES: 
# - amcl params where removed. They are not needed because global localization is provided
#   by an ekf node on robot_localization fusing gps data with local odometry sources
# - static layer is removed from both costmaps, in this tutorial we assume there is no map
#   of the environment
# - global costmap is set to be rolling to allow the robot to traverse big environment by
#   following successive relatively close waypoints that fit in a smaller rolling costmap

启动后没有报错，但是我不清楚如何给它机器人的初始位姿和目标点的位姿，如果使用rviz2里的插件在map上给的话会有报错：

我一开始以为是我的global_costmap大小太小没有把目标点也包含在内，但是之后我将global_costmap改大之后还是报同样的错误。

会不会是我那个自己写的定位节点除了发布map->odomtf转换之外还需要别的？
