Two revolute joints at the same place is not working as expected

Hi All,

I have created two revolute joints along x and z axis correspondingly at the same place in the attached usd. But I see that when I am playing the scene only one joint is working at a time. I have checked that both joints are working individually but not together. Can you please let me know is there any way i Can make it work for both the joints?

Please find the attached usd.

Thanks and Regards,
Santu

Revolute joints restrict all degrees of freedom except the rotational axis. The best way to achieve what you want is to add a rigid body in between with a mass/inertia but no collision.

body_link → revolute_x ->dummy_link->revolute_y->shoulder_link

Thanks a lot. It’s working now.
