Ok so why can iron man's armor not pick up Thor's hammer like vision did if the suit and vision are similar?

Ok so vision was created using that machine that created life like flesh or whatever and was uploaded with jarvases program so I think. If vision picked up Thor's hammer the same way an elevator or a plane could then why can't Tony Stark's iron man suit using the same type of functions not be able to weild it like vision.
