Hi @904798869,

I think this is best asked in the Omniverse->Isaac Sim category. I move your post over.

Thanks!

Hi @904798869

This link may help:

(…) You can either keep usePath checked and type in the path to the robot articulation in the robotPath, or you can uncheck usePath and then click Add Targets near the top of the pane for input:targetPrim, and select the robot articulation in the pop up window.

Do you have a detailed example? My car has a four-wheel differential and I don’t know how to set it up，thanks

Hi @904798869 , for the articulation controller to work, you need to setup the robot as an articulation. Here is a link to an Isaac Sim tutorial which has more details.

Hope this helps!
