New Unity User: Rotating Joints in Robot Kyle

Hello, I’m a new Unity user looking to do a certain function within Unity. I saw that after downloading the Robot Kyle assets from the Asset Store, there are several different children under the root. Each one of these (Hip, Ribs, Neck, etc.) can be individually rotated from within Unity. I wish to make a Unity script controlling the rotation of these joints, as well as the positions of them. In a C# Unity script, how do I reference each of these child joints in order to control them from the script?

The skeleton in Unity is a hierarchy of regular Unity transforms. You can get the specific joints by finding them by name, or starting at the root and then walking the skeleton hierarchy using transform.GetChild().
