@1769564038
1.第一张图片是启动什么指令报的错
2.你的目的是让自己配置的机械臂点击exevute的时候在rviz中动起来是吗？如果是其实这个通过的是fake_controller进行的
3.提供一下rqt_grapher、rostopic list 、rostopic echo /joint_states 的结果和你的机械臂的urdf文件，你的错误应该是某一个类型对不上造成的，需要进一步检查

另外请尽量复制粘贴代码，我这边好方便引用和检索。

一个好的提问不仅能够帮助自己理清楚问题，还有助于别人快速帮助到你。——提问的智慧

问题一定要描述清楚，终端打印一定复制粘贴（你可以在linux系统上打开浏览器进社区）
基本的Markdown语法一定要学习下，有的小伙伴图片代码一团糟
提问时一定要提供尽可能多的信息(系统版本，ROS版本，前后操作，终端日志)，包括你的目的，比如你其实想装装某个库遇到问题，不要只说这个问题，因为可能有更好的替代方案
先搜索再提问，很多问题其实都有解决方案，确保你自己对自己的问题有一定了解再提问

roslaunch robot_gazebo robot_bringup_moveit.launch
这是我启动的指令，然后在rviz里面点击execute的时候报的错误如下错误

[ERROR] [1669182292.117079150, 31.722000000]: Unable to identify any set of controllers that can actuate the specified joints: [ joint_1 joint_2 joint_3 joint_4 ]

[ERROR] [1669182292.117213348, 31.722000000]: Apparently trajectory initialization failed

我是想在gazebo里面动起来，通过rvize界面发送指令让仿真机械臂动起来。

@1769564038 在 Unable to identify any set of controllers that can actuate the specified joints: 中说：
贴一下你的robot_bringup_moveit.launch内容，另外如果是控制gazebo的机械臂需要gazebo来提供joint_states和actionserver,所以你要提供下rqt_graph,确定下gazebo是否正常再检查moveit这边

rqt_graph别忘记了

@小鱼在 Unable to identify any set of controllers that can actuate the specified joints: 中说：

3.提供一下rqt_grapher

不好意思鱼哥，等久了，我终于把我的grapher调出来了。

问题已解决，主要问题是gazebo里面没有添加gazebo标签。

小鱼

@1769564038 棒，这种复杂的问题，可以就是一块块的检查，你的gazebo这边的rqt_graph看起来就是不正常的，啥都没提供。

扶苏

@1769564038 您好，请问哪个文件里没有添加gazebo标签，能具体说一下吗

ㅤ

@1769564038 大佬，我也遇到了和你相同的问题，可以具体说一下解决方法吗，感激不尽。
