Carter_v2 urdf & Mesh

Hi,
I’m trying to follow the tutorial ( Multiple Robot ROS Navigation) using carter_v2(Below figure).

But for using that tutorial, i have to need the urdf and mesh of carter_v2.
But Only carter_v1 urdf and mesh are provided in Isaac Simulator.

So,
Where and How can i get the urdf and mesh of carter_v2?

Thank you :)
