@775405893 雷达驱动意外挂了，重新运行下试试

775405893

@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。

小鱼

@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？

小鱼

@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

ist，查看是否有scan话题。

找不到/scan的话题

我也是同样的问题没有scan 出来系统是ubuntu24.04 jazzy 版本，这个要怎么解决

小鱼

@279401783 大概要换系统，或者使用后面的源码方式使用

请问这个是什么问题呀，出现下面这个错误，已知ping可以正常运行，雷达是转的，跳线帽也是对的，ip地址配置正确，处于RUN MODE模式
