4-mecanum-wheeled Robot not moving

Hi,

I’m working on a Robot with 4 mecanum wheels, which i copied from the O3dyn and scaled them down. I also built my ActionGraph like the one for the O3dyn, but my robot is not moving, without giving any error messages. I gave all wheels the needed attributes for radius and mecanum angle and selected the right prims in the USD Setup and articulation controller node. The articulation Controller is getting the velocity commands fromt’the holonomic controller, but somehow the wheels dont spin. I attached the usda file, can someone please help me with that? Thank you!
