【control_manager】无法加载，gazebo_ros2_control 0.4.8，机械臂乱飞

删除URDF和SDRF文件中的特殊注释#, !,：

xacro文件解析为字符串时出现报错

一开始疯狂报错Waiting for '/controller_manager' node to exist

1）是控制器没安装，把所有控制器都安装一遍后

sudo apt-get install ros-humble-controller-manager
sudo apt install ros-humble-ros2-control
sudo apt-get install ros-humble-gazebo-ros2-controlsudo apt install ros-humble-gazebo-ros-pkgs

Controller manager not available in ROS2
确认安装

ros2 pkg list | grep ros2_control
ros2 pkg list | grep ros2_controllers

#更新软件源
sudo add-apt-repository ppa:openrobotics/gazebo11-non-amd64
sudo apt update
# 安装gazebo11
sudo apt install gazebo
sudo apt install ros-humble-gazebo-*

此时，注意到gazebo_ros2_control为最新版0.4.8

我遇到的问题就是在另一台虚拟机上可以正常进行moveit2+Rviz+Gazebo的联合仿真，但是相同的文件换一台电脑就无法执行了。
Rviz中显示报错TF有部分显示No transform from [..._link] to [world]

2)命名空间问题？Unicode编码？Fix Frame设置？gazebo世界模型加载失败？

安装Unicode

sudo apt-get install unicode 

下载Gazebo模型到本地~/.gazebo/models

cd ~/.gazebo/models/
wget http://file.ncnynl.com/ros/gazebo_models.txt
wget -i gazebo_models.txt
ls model.tar.g* | xargs -n1 tar xzvf

rviz模型显示异常，且rviz中提示rviz No transform from [link1] to [link2]

/spawn_entity无响应，RViz模型加载失败
