update to ros2

[QILIANGDELEISHUI]

I am a beginner of ros2, thank you very much for developing this plug-in, which helps me to build complex models in visual graphics software and can be easily displayed. I recently encountered an issue where urdf files generated using this plugin and STL files in the meshes folder could no longer be visualized in gazebo, in the ros2 environment. I can't solve the problem, and I can't judge the source of the problem. However, in 2024, ros1 is already lagging behind, would you consider upgrading this plugin to ros2? . Requests from beginners. Thank you very much!

I created a small tool in my repository that can convert the directory generated by sw2urdf into a format compatible with ROS2. It allows the model to be displayed in both RViz2 and Gazebo. I have already tested it and confirmed it works on Humble.
