鱼哥，如果我要自己写控制算法，应该在哪里改，没找到源码的控制算法在那里
-
@safereinforcementlab 我重新装了ros2，就好了
-
请问在这个程序里面，具体的控制算法程序在哪里，https://github.com/fishros/fishbot，没有看到

@小鱼
鱼哥 都做完了 最后给了小车目标之后 他只是转了个向 并没有移动 我看雷达这边报了警 是这个原因吗？ 还是因为什么？ -
@1147022743 这个警告没关系，是Qos 主要是你这膨胀半径太大了吧
-
@小鱼 鱼哥，我安装依赖是成功的，但是在编译的时候我也出现了这个问题，请问该怎么解决
-
@blairan121122885 解决了吗，跑了一次一键安装？
-
@192224801 同样问题解决了吗
-
@小鱼 鱼哥这一步跑一键安装，输入命令后安装第几项？
-
@小鱼
鱼哥，卡在“fishbot_bringup”这里了，没找到如何解决的方法呢，帮我看看怎么个问题，多谢

我下载的NAV2的代码为什么编译阶段会报错

@1032063747 第二个命令应该在第一个后面输入，注意终端目录

@小鱼 在 [FishBot教程]7. FishBot-Nav2导航测试 中说：
source install/setup.bash
ros2 launch fishbot_navigation2 navigation2.launch.py哥，我前面都弄好了，最后一步点击Rviz2工具栏——2D Pose Estimate没有反应是什么原因？
，是Ubuntu22.04，humble版本，前面的都没问题，知道一下呗，很急！！！重试了很多次都是没反应。 -
@1923825015 你提供的信息不足，连个日志都没有
@小鱼 在 提问前必看！一定要看！必须看一下！ 中说：
一个好的提问不仅能够帮助自己理清楚问题，还有助于别人快速帮助到你。——提问的智慧
问题一定要描述清楚，终端打印一定复制粘贴，方便回答者检索和引用（你可以在linux系统上打开浏览器进社区）
基本的Markdown语法一定要学习下，有的小伙伴图片代码一团糟
提问时一定要提供尽可能多的信息(系统版本，ROS版本，前后操作，终端日志)，包括你的目的，比如你其实想装装某个库遇到问题，不要只说这个问题，因为可能有更好的替代方案
先搜索再提问，很多问题其实都有解决方案，确保你自己对自己的问题有一定了解再提问
尽量一句话说完，不要把社区当微信聊天一样用，每一个回复都尽量提供更多的的信息。
