Could you provide/upload the folder with the urdf description and meshes to try to reproduce it?
Btw, the Isaac Sim 2020.2 version has a better urdf import extension.
The urdf could be imported successfully in Isaac Sim 2020.2…
Btw, it is necessary to import this urdf with the Fix Base Link parameter unchecked. After that, you have to add a Fixed joint for the base_1 XForm/link To world space (All operation in the Physics menu). If you does not uncheck this parameter the robot will be loaded with the hand fixed to the world (Why? Idk).
It it glad hear that it works with new Omiverse version.
I am going to migrate from ROS Gazebo to Omiverse because I checked it has
many various option for Deep Learning.
I am glad to hear about it.
Come back here any time…
Btw, if any response of this post was your solution you can also check the Solution checkbox to close this post successfully 😅
