How to make an object move without an attached object moving with it

I’d like to know (if it’s possible) how to move the main object (the parent I suppose) but keep it’s children still and not moving.

In the provided image I have a sphere with a cylinder, a cube and a SpringArm attached to the cube. What I would like is for the ball to move around without the cylinder, cube and SpringArm moving with it. What I’d like to know is: How would one do this?

Any advice would be greatly appreciated!
