I’m trying to build a legged robot with an arm. I hope the joint order follows [base_dof, arm_dof]. However, when I import my urdf, the joint indices have changed. (I find out this by Articulation Inspector). Is there anything wrong with my URDF? Thanks a lot!

I change the parent link of joint1
from trunk
to imu_link
, then the joint indices is correct. But I still don’t know how the physics engine of Isaac Sim works to figure out the joint indices.😥
