原因·：对于mesh文件（dae、stl），gazebo那边识别不了 package://claw_description 这种ros系统的路径查找方式（尝试运行的话，gazebo直接卡在那里），只能用 $(find claw_description)这种方式找到绝对路径并替换。

@ls3470319318 在 launch文件启动gazebo 中说：
[ERROR] [robot_state_publisher-1]: process has died [pid 18641, exit code -6, cmd '/opt/ros/humble/lib/robot_state_publisher/robot_state_publisher --ros-args --params-file /tmp/launch_params_xpjnnng3'].
参数文件看起来不太对，你把完整的报错拿出来，另外尽量抄一下书上的代码
