Hello, it has taken me a while to sift through the API docs and the other SDF samples, but I'm still not able to quite get this ball-on-beam sdf functioning as expected. The previous version was highly unstable prev version.

The current version doesn't isn't controllable. Maybe a gearbox is needed? Maybe I shouldn't actually try to use a real object that can leave the surface of the beam?

Any suggestions?

For reference, here's one clip of the model in the wild..

Maybe you can try to add some friction on your upper_joint. If you want an accurate model, you will also have to set the inertial matrix for your links.

You can visualize the inertia matrices by right-clicking on the model, and selecting View->Inertia. The purple boxes should roughly match the collision/visual objects. Ref:
