[FishBot教程]9.0.7. FishBot-Nav2导航测试

[15724948]

在做nav2导航测试，为什么有个标识车辆位置的点在图外。左下角的位置。是否中间什么点错了？
目前目标位置，车子可以正常过去。
有时发现车子检测的位置和地图不匹配，有方向偏移或位置偏移，这个如何矫正。

发现的其他问题1：
过一段时间雷达会超时（时间不固定ctr+C，退出，重新选1驱动雷达。数据会正常。l

发现的其他问题2：
rviz2中雷达数据和小车状态不更新，提示queue is full
处理方式：关闭rviz2,重新启动程序ros2 launch fishbot_navigation2 navigation2.launch.py

左下角是odom转换正常，雷达这边考虑网络问题

@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

这一步，先跑一次一键安装

[lzw]

@小鱼 安装过了，最后还是这样。

@lzw 下次最好单独提问，不然容易看不到帖子。

这个问题之前应该出现过，提示缺少的那个包装一下就好（最好复制粘贴错误，我也好复制粘贴给你命令）

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

1.请使用ubuntu22.04 系统 2.请安装 joint_state_publisher

就是这里

sudo apt install ros-humble-joint-state-publisher

[lzw]

跟着文字做到第五步导航测试时输入命令出现以下错误：
版本为22.04

[小鱼]

@lzw 工作空间不对，你的目录在主目录了，应该到工作空间下执行

我在拉取项目，也就是文中第二个命令时，出现了下面的错误：正克隆到 'fishbot'...

@2462331351 换个github代理试试

[2462331351]

@小鱼 换了，发现还是不行，我去我的windows（可以正常Google的）发现还是有错误```

我说的代理是这里的网址

[2462331351]

@小鱼 我不太明白，请问
这个代理怎么换呀

我在运行sudo apt install ros-humble-joint-state-publisher发生下面的错误，我换源了但是还是会从清华源下载，真不知道怎么办了我的小车都连上了

我在运行到最后一步时，雷达镜像出现了下面的问题：```
[WARN] [1724764700.139124810] [ydlidar_node]: New subscription discovered on topic '/scan', requesting incompatible QoS. No messages will be sent to it. Last incompatible policy: RELIABILITY_QOS_POLICY

[小鱼]

@2462331351 这个不是错误，可以忽略

[小鱼]

@2462331351 在 [FishBot教程]7. FishBot-Nav2导航测试 中说：

sudo apt --fix-missing

[HermitWJ]

一、下载与编译导航代码

打开终端，输入下面的指令。

git clone https://github.com/fishros/fishbot.git -b v1.0.0 --depth=1
cd fishbot
rosdep install --from-paths src --ignore-src -y -r # 安装依赖
colcon build

执行最后一步colcon build报错

以下是报错信息：

@HermitWJ 问一下你的操作系统版本信息，还有你把代码放到了哪个位置，不要放桌面之类的奇怪位置哦
