Help I want to shake what I attached to the rod

[nyame]

If I understood correctly, you want the sphere at the end of the rod to "wiggle" with it, right? Kinda like the "spring rod" sample scene.

This should work just by using a dynamic attachment, provided that the sphere is a rigidbody. Let me know if you hit any issues or have any problems using this.

You understand exactly!
I want to put a rod and sphere antenna on the head of a square robot and shake it cutely.


Should I connect the spheres with obi particle attachments and make the type dynamic?

The spheres moves violently and goes somewhere. 
Rigid body, obi rigid body, sphere collider, obi collider are set on the spheres.

I saw a "spring rod" sample scene, which is very similar to what I want to do.
The obi rope I'm using is 5.0 so I didn't understand...sorry.
It would be very helpful if you could give me a hint.Thank you.
