我docker中以Ubuntu20.04为镜像创建了包含ROS noetic的容器，现在无法驱动真实机械臂

[ChuckAlex]

我的机械臂型号是RM-65，已经按照介绍页面所说的去掉了load controllers.yaml.的注释，但是现在Motion Planning一直是warn状态，请问我应该怎么解决
看终端输出信息有下面俩个报错
[ERROR] [1723189561.492637086]: No sensor plugin specified for octomap updater 0; ignoring.
[ERROR] [1723189577.180458991]: Action client not connected: rm_group/follow_joint_trajectory

拖动rviz界面的机械臂可以plan但不能execute，报错如下
[ERROR] [1723189837.117922724]: Unable to identify any set of controllers that can actuate the specified joints: [ joint1 joint2 joint3 joint4 joint5 joint6 ]
[ERROR] [1723189837.118033730]: Known controllers and their joints:

[ERROR] [1723189837.118611296]: Apparently trajectory initialization failed

同样的问题，解决了吗

At present, many data information of robotic arms are actively reported, and the prerequisite for active reporting is to obtain your address. When using Docker environment, it is very likely that your IP address is not publicly available, and if the robotic arm cannot obtain your IP address, it will not be able to report information, ultimately leading to problems.
Solution: Currently, it has not been tested in an actual Docker environment. The key is whether another external device can ping the Docker address.
目前机械臂的很多数据信息是主动上报的，主动上报的前提是能拿到你的地址。使用docker环境时，你的IP地址很有可能对外是不公开的，机械臂拿不到你的IP地址，就没有办法上报信息，最终导致问题。
解决方式：目前没有在实际的docker环境测试过，核心就是，外部的另一个设备能不能ping通docker地址。
以上是我的分析，希望对你有所帮助。
