Bringing my robot into Isaac Sim

Hi everyone. I created a 3D model and defined all the physics (joints, rigid bodies, and so on) but when I make it move using omnigraph, it is no following the expected movement. Here I included a video of what is happening. If anyone has any suggestion, please let me know. The front tires have defined revolute joints and angular drives as well as for back tires. Do not understand why they are not rotating accordingly.

You can do these things.

  1. In Articulation attribute, disable self-collision - this helps avoid collision when your chassis collision mesh overlap with the wheels collision meshes.
  2. Change the collision mesh of the wheel to sphere approximation - the initial mesh can cause disturbance, imagine your wheel is a polygon while the ground is flat.

2*. The option that I suggested is “Bounding Sphere”
3(Optional). Draw a simple collision mesh your self or use a simple mesh approximation for the chassis.
