使用鱼哥第七章的fishbot_navigation2功能包想做实体小车导航。问题是2D pose estimate后全局代价地图和局部代价地图始终不显示,请鱼哥和各位大佬看看我朝哪个方向排查:
详细描述如下:
1.版本:ROS2 jazzy ubuntu24.04 树莓派5。激光雷达是实体单线雷达 自己搓的麦轮小车,能发布里程计(自己测试还挺准的)
2.使用里程计小车能找到自己的位置,配合雷达能完成家里客厅的简单建图
3.nav2_params.yaml 和 navigation2.launch.py(这个launch里调用了nav2_bringup,传参是map_yaml_path,use_sim_time,和yaml文件路径)是在鱼哥的基础上改的,主要修改的1)use_sim_time: False 2)没有URDF,所以发布了一个 1hz的base_footprint->base_link->laser的TF 3)其他小的参数改动
4.运行navigation2.launch.py后,查看TF都正常,2Dpose estimate后能看到周围有粒子(看样子负责定位的自适应蒙特卡洛粒子滤波起作用了),但是代价地图(全局 局部)都不显示 代价地图模块说no map received
5.显然在代价地图说收不到map的情况下点NAV2 GOAL也是无效的 terminal说 没有设置起始位置(但是其实我设置了)
6 补充:我在目前的基础上丧心病狂的再运行一下ros2 launch nav2_bringup navigation_launch.py 代价地图就有了(代价有点大 我家客厅有点小😕 ),但是NAV2 GOAL还是失败
请各位大佬指点一二,帮我看看我的问题可能在哪:
**问题1 我没有代价地图的问题可能在哪?
初始位置没设置对?(AMCL模块正常,TF显示map->odom)
代价地图的YAML没配置对?(我跑鱼哥的yaml仿真能跑,仅仅改了footprint坐标系和仿真时间)
为什么我运行ros2 launch nav2_bringup navigation_launch.py 能出代价地图?
问题2 我运行ros2 launch nav2_bringup navigation_launch.py 显然是不应该有的做法,让节点重复发布了。这时候不能导航仅仅是因为节点重复发布的原因吗?还是我还有一些别的没做对?**

这是点2d pose estimate后的结果

这是此时的TF

这是此时的节点

这是小车反馈信息 里程计发布应该都正常(这个图是我后截取的,用遥控器控制小车 确认小车发布的里程计有效)

这个是再没有代价地图的情况下强行点NAV2GOAL的结果

这个是运行一遍ros2 launch nav2_bringup navigation_launch.py 后的结果,注意此时节点几乎都存在两个同名节点,不知道不能导航是否和同名节点有关,但是起码运行这个显示代价地图了

这个是在运行ros2 launch nav2_bringup navigation_launch.py后有代价地图 点NAV2 goal的结果
