Is it possible to implement equipment that uses a pulley method in Isaac Sim using Rigid Body, Collider, and Joint?

Hello @toni.sm, Long time no see.
I’d like to physically implement something similar to a conveyor belt but with a different pulley system, and I’m not sure if that’s currently possible in Omniverse and Isaac Sim. And if this is possible, I’m not sure which Joint to use.

This facility uses a pulley method to make the gripper body that picks up the box move up and down.

Please refer to the photos and video below.
The movement of the equipment in the video was made to move with a simple action graph, and no physical rigid bodies were included.

Due to the complex equipment and modeling, the frame falls with many colliders and rigid bodies, but the overall movement of the equipment is made to move by connecting revolute joints to the wheel and body.
As shown in the picture above, I want to physically move the pulley method as well.

Hi,
We are planning to release C++ Omniverse PhysX Examples, where one can implement its own type of joint, for example pulley joint. (thats actually an example of a custom joint in PhysX SDK and will be available as an example in the released C++ Omniverse PhysX Examples). However till this is released you would have to cheat somehow by adding a prismatic joint to restrict the movement long the axis and using joint drive to drive towards a desired position.

Regards,
Ales
