有啥比较一条龙(除moveit)的实现方案么。
除开视觉部分，我找到用tesseract库，但是，它的专属srdf模型生成工具，5年没有维护，已经用不了了，从moveit改，太困难了。

moveit2我上手，感觉难度曲线有些陡峭

您好：
目前我想讓TB4可以自行導航，但現在遭遇幾個問題：

我們目前遭遇到Global Status為error，RobotModel的status為error，有嘗試重連後還是沒辦法執行。

配置好后出现这样，WiFi显示 ping timeout

四驱v2的主控板使用下载的固件里程计正常，使用源码编译的就没有读取不到里程计数据和更新，使用了master版本源码和最新的2.0.6的源码都不可以

按照图中下载示例代码部分中，出现一下提示。且两条都是如此，寻求一下解决办法

fatal: 目标路径 'moveit_tutorials' 已经存在，并且不是一个空目录。

我尝试在Nav2官方的示例上修改，但是今天启动的时候我却遇到了莫名奇妙的tf帧时间同步错误。下面是我的配置文件，同样的配置文件在昨天还是工作正常的。

我检查了我的其他配置文件，确定这些配置在之前都从未修改，工作正常。
请大佬看看我是不是错漏了什么？

[ERROR] [1753014823.444899784] [move_group_interface]: Failed to fetch current robot state

根据官方文档一直查到提示信息在waitForCurrentState()的函数中被打印，函数主要逻辑是使用while阻塞等待回调执行，直到接收到数据的时间戳大于指定的目标时间，但是为了避免一直阻塞，函数会在每次循环求出与初始时间的间隔，然后做一个超时判断，可以看到提示信息第三个浮点数，含义是接收到数据的时间戳，但是它为0，这说明在对象初始化结束后，从未接收到过数据，回调函数没有被执行。检查回调绑定的函数startStateMonitor()，函数接受默认参数主题名joint_states，然后绑定回调然后打印监听中的信息。但是回调似乎不被执行。

已验证主题存在，并且数据正常发布，自已写一个订阅节点也能够正常输出得到的时间戳。

使用ROS2 humble开发机器人导航系统，主控机除了接入底盘STM32外，还接入了雷达和IMU。
请问我该选择树莓派4B还是5？

运行如下代码时，如果使用fish的源码会出现的问题，

有:

就是时间戳的问题，因为我增大过slam_toolbox的online_async这个文件的配置文件的栈的大小和保存数据的时间但是都没有效果,也不是网络问题，然后就发现了只可能是时间戳的问题。电脑有自己的时钟，小车也是，就发现了odom2tf.cpp文件里面的一个地方出现了问题，时间戳应该都要用电脑的时间戳，不能两者混在一起。
具体的解释你们可以把代码发给AI问一下，我可能说的不清除，但是一定能解决。
只要按照下面的方法把时间戳统一到电脑的就完美解决问题了,
找到odom2tf.cpp文件，按照下面的改:

报错代码如下

是跟镜像问题相关吗？我在安装PlateformIO MicroROS开发环境前已经用一键安装命令更换了系统镜像源，并且根据视频教程【《ROS 2机器人开发从入门到实践》9.2.1开发平台介绍与安装】 https://www.bilibili.com/video/BV1pLf2YxEzv/?share_source=copy_web&vd_source=b55b762ce28a6ddb1537f871dc7d4a1d 配置完platformio.ini文件后，用

pio run

编译运行时下载速度也特别慢。求各位大佬指点下解决方法。

如题，我自己整了个YDLIDAR X2激光雷达，用wifi发给电脑能收到，但是小鱼的雷达驱动的tcp通信无法解析，我想知道通信协议。

鱼哥，wifi连接正常，雷达模式调到了WiFi模式，小车和虚拟机都连接到了一个WiFi，但是接收不到雷达数据，请问是什么原因呢

虚拟机使用VM，系统乌班图22.04
