@小鱼 不好意思，这个没考虑到
-
@1281857896 这个参数是哪里来的
-
@小鱼 第17章建图与导航实践 fishbot导航实现 fishbot导航实现那块安装了nav2功能包，然后从功能包里复制出来的参数就这么多，我刚打开功能包确实是这些参数
复制的时候用的下面这个命令
cp /opt/ros/$ROS_DISTRO/share/nav2_bringup/params/nav2_params.yaml src/fishbot_navigation2/config -
@1281857896 你从快速上手教程里拷贝试试，或者直接用快速上手教程里的导航配置跑跑，看看能不能跑起来
-
@小鱼 有些参数不一样

@小鱼 鱼哥，用最新的底板固件加上快速上手里面的fishbot.yaml可以很好实现导航，用那个fishbot_nav2.yaml就会加载不出地图，跑不了，应该是有缺东西
-
第三步，话题里面有scan，但出现警告是怎么回事
-
@1281857896 对比下文件区别，可能哪里不对劲的
-
-
-
-
@775405893 雷达驱动意外挂了，重新运行下试试
-
@小鱼 ubuntu 24 ，ros2是jazzy版，虚拟机桥接，雷达连的电脑热点。重启了一下还是这个问题，雷达地址能ping通。
-
@775405893 估计是版本问题，docker里面是22.04的，最好主机也用22.04，教程也是22.04的，还会有坑等着你。你那里有书吗，书上有源码驱动雷达的方法，只能用这个了，或者你需要等一段时间（半个月左右），我抽空时间来适配下24.04系统。
-
@小鱼 好的谢谢，有书，我现在去翻一下
-
@775405893 第九章，你找找
-

请问小鱼有没有解决办法，有没有类似 miroros agent 的离线解决方案？ -
@466413819 arm架构下不支持这个镜像，需要按照
拓展1：FishBot配套雷达驱动教程（源码版）
拓展2：树莓派上使用micros-agent驱动主控板的方法
拓展3：FishBot 树莓派配置建图导航
