[FishBot教程]7. FishBot-Nav2导航测试

h1

@小鱼好吧，目前我就是源码编不过，其他都可以，有没有什么方案能解决下这个问题呢，大佬

小鱼

@429016267 看d2lros2教程前面的仿真部分，根据提示重新从原来的仓库克隆

@小鱼在 [FishBot教程]7. FishBot-Nav2导航测试中说：

rosdep install --from-paths src --ignore-src -y -r # 安装依赖

在安装依赖时报错，用的ubuntu22.04 humble版本然后图上的网址打不开。

鱼哥，这是什么问题

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

@safereinforcementlab 我重新装了ros2，就好了

safereinforcementlab

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？

小鱼

@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

大道至简

@blairan121122885 解决了吗，跑了一次一键安装？

大道至简

@192224801 同样问题解决了吗

大道至简

@小鱼鱼哥这一步跑一键安装，输入命令后安装第几项？

大道至简

@小鱼截图 2024-02-20 20-03-27.png 截图 2024-02-20 20-13-53.png 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
