兄弟你解决了吗，我也遇到这个问题了。
这是我在将宇树四足机器人go2的ros1开源代码移植到ros2时遇到的问题。
造成这个问题的原因是，在ros2的launch启动文件中，写入了加载控制器节点，但是ros2的controller_manager在搜索控制器时却搜索不到。所以解决本问题的思路是如何让controller_manager知道在哪搜索控制器。
1）新建xacro文件，添加ros2_control标签，并在标签中定义控制器，并加入你的yaml文件路径。注：如果你也是ros1移植ros2，要注意ros1定义控制器的标签是transmission，在ros2中已经替换成了ros2_control标签，你需要将transmission标签换成ros2_control标签，包括里面的内容也可能需要修改
<?xml version="1.0"?> <robot xmlns:xacro="http://www.ros.org/wiki/xacro"> <!-- 声明宏 --> <xacro:macro name="your_controller" params="name"> <!-- 需要替换成你的名字，可随便起 --> <ros2_control name="your_hardware_interface" type="system"> <!-- 需要替换成你的名字，可随便起 --> <hardware> <plugin>gazebo_ros2_control/GazeboSystem</plugin> </hardware> <joint name= "your_joint"> <!-- 需要替换成你的名字，需与模型文件里的关节名一致 --> <!-- 命令接口：力矩控制 --> <command_interface name="effort"> <param name="min">-10.0</param> <!-- 实际值需根据电机调整 --> <param name="max">10.0</param> <!-- 单位：牛顿米(N·m) --> </command_interface> <!-- 状态反馈接口 --> <state_interface name="position"/> <!-- 关节位置 --> <state_interface name="velocity"/> <!-- 关节速度 --> <state_interface name="effort"/> <!-- 关节力矩 --> </joint> </ros2_control> </xacro:macro> <gazebo> <plugin filename="libgazebo_ros2_control.so" name="gazebo_ros2_control"> <parameters>$(find your_pkg)/config/your_config.yaml</parameters> <!-- 需要替换成你的包名和路径 --> </plugin> </gazebo> </robot>2）修改yaml文件格式，确保格式正确
controller_manager: ros__parameters: update_rate: 100 # Hz use_sim_time: true # 控制器列表及类型 joint_state_broadcaster: type: joint_state_broadcaster/JointStateBroadcaster your_controller: type: unitree_legged_control/UnitreeJointController # 各个控制器的具体配置 joint_state_broadcaster: ros__parameters: # No specific parameters needed for the broadcaster usually update_rate: 1000 # FL Controllers Parameters your_controller: ros__parameters: joint: your_joint command_interfaces: - effort state_interfaces: - effort - position - velocity #!!!your_controller名字需一致3）如果你也是ros1迁移ros2，需要注意在xacro文件里的很多插件，如gazebo_ros_control，是ros1提供的插件，但是在ros2中是不能使用的，所以需要对其注释掉或者修改

由于没有aarch64平台的nav2，所以自行编译了nav2，下载了gazebo_ros_pkgs和navigation2两个包，编译后运行官方示例，发现gazebo和riviz都正常启动，但是gazebo的激光雷达线束并没有展示出来

./install/nav2_costmap_2d/lib/liblayers.so用ldd命令查看这个动态链接库是否加载成功，发现是正常加载的，然后用nm的方式去找，也能找到VoxelLayer和StaticLayer的符号，证明这个动态链接库是没问题的，然后就去找动态库的路径是否有放在LD_LIBRARY_PATH里面，发现也是有的，后面写了个简单的demo去加载VoxelLayer和StaticLayer，发现也是正常加载，但是运行官方示例就没办法加载这两个插件，导致整个项目运行不起来，实在想不通是为什么

目前可以在ros中打开groot，解锁后可以拖动行为树相关的节点，但是没有找到咋运行拖动后的文档，怎么让ros2里面实现通过直接拖动行为树来模拟仿真飞行

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

首先是提示信息:

Check clock synchronization if your are running ROS across multiple machines!
[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。
