Autodesk Inventor- parts act as if in sub-assembly

I am making a tri-star wheel in Inventor and I am making the whole tri-star wheel an assembly, so when I import it into my Robot, I don’t have to remake the wheel. How do I get the wheel, along with the gears inside of the wheel, to move when I place the tri-star wheel in the Robot assembly? I am not asking how to get the rotational constraints set up, I am wondering how to get the whole tri-star wheel to act as if it is made up of seperate parts, instead of one whole piece.

You need to turn on “Flexible”. Right-click on the Assembly and you should see “Flexible”. Click on it to turn it on.
