新手小白在做一个可动小车的仿真时，遇到了如下问题，恳请各位相助！
我在RVIZ里查看小车模型时可以得到下图所示的模型图
小车模型图.png
但是当我输入命令
roslaunch steer_mini_gazebo steer_mini_sim.launch
在gazebo中驱动小车时，却出现了如下报错
[ INFO] [1701960022.508446103, 61.242000000]: gazebo_ros_control plugin is waiting for model URDF in parameter [robot_description] on the ROS param server. [FATAL] [1701960022.609885892, 61.242000000]: Failed to create robot simulation interface loader: Could not find library corresponding to plugin steer_bot_hardware_gazebo/SteerBotHardwareGazebo. Make sure the plugin description XML file has the correct name of the library and that the library actually exists. [ INFO] [1701960022.610109458, 61.242000000]: Loaded gazebo_ros_control.且在RIVIZ中车轮的link也无法识别，如下图所示

在网上找了很久都没找到解决方案，恳请各位大佬帮忙！万分感谢！
