求助，使用官方代码和套件导航部分出错

小鱼

@1683127550 雷达话题呢

ppqppl

@小鱼雷达偶尔几次连接时会出现这样：
#? 1
UART2SOCKET:8888->/tmp/fishbot_laser
Prepare to Accept connect!

但是连接成功之后还是没用，目前雷达没问题

小鱼

@1683127550 连接成功后有全部重启吗

ppqppl

@小鱼启动后直接连接就不行，连接后全部重启之后还是不行

小鱼

@1683127550 倒是贴一下终端日志，日志会告诉说为什么不行

ppqppl

中断一直输出这一个

小鱼

@1683127550 看一下fishbot_bringup 终端输出，这个节点负责发布 odom 到 base_link 的变换

是这样的

小鱼

@1683127550 动一下小车，看一下数据是否有变化，全部都是 0 有点不正常

ppqppl

@小鱼就是我用键盘节点控制车吗，我明天试试，今天上课没啥时间，我想问一下，如果没有车能运行那个自动导航的launch吗，还是有别的部分能代替，做没有车的情况下的自动导航？

小鱼

@1683127550 没有车的情况可以采用仿真形式：https://fishros.com/d2lros2/#/humble/chapt9/get_started/1.机器人仿真介绍

ppqppl

@小鱼有开源代码集吗，类似于github开源库那种

小鱼

@1683127550 fishbot的主分支可以直接仿真使用：https://github.com/fishros/fishbot

ppqppl

@小鱼现在这个导航还是不行

数据还是一直这样，其他部分都是好的，只有小车自动导航这里不行，移动小车数据不变，然后另一个中断返回值是这样的：

小鱼

@1683127550 这个数据不太正常，检查小车线有没有松，能不能键盘控制移动

ppqppl

此回复已被删除！

ppqppl

@小鱼雷达和里程计测试通过，所有线都没有松动，现在数据是这样的

用键盘控制小车，第一张图中数据发生改变

但是小车自动导航的还是不行

这里我点了 2D Pose Estimate 还是没有反应

小鱼

@1683127550 rqt tf tree 看下

ppqppl

@小鱼
我重新下载了一下源码编译了一下，现在和刚才错误显示不一样了

这个是 rqt-tf-tree

我这边给出小车的初始坐标和方向之后，显示这些，好像是有我点击的点的信息，但是小车那边还是没反应

在这个基础上我重启了一下雷达，然后显示这样：

ppqppl

@小鱼我搞定了，多谢，我看了一下 rqt-tf-tree，改了一点东西就好了
