我是在练习机器人操作系统理论与实践
首先下载gazebo模型
然后将将gazebo模型的相关模型添加进去，具体看这个网址

最后运行roslaunch文件出错了
错误如下：
No such file or directory: /home/cez/catkin_ws/src/urdf/xacro/gazebo/mbot_gazebo.xacro None None
Invalid tag: Cannot load command parameter [robot_description]: command [/opt/ros/kinetic/lib/xacro/xacro --inorder ‘/home/cez/catkin_ws/src/urdf/xacro/gazebo/mbot_gazebo.xacro’] returned with code [2].
Param xml is
The traceback for the exception was written to the log file
解决如下
将 mbot_description 添加进去 ROS_PACKAGE_PATH=~/catkin_ws/src/mbot_description:$ROS_PACKAGE_PATH
然后再紧接着运行就可以啦
