There are a lot of things we consider intelligent actions that we do unconsciously. I recommend reading "Incognito - David Eagleman" it basically says that the simpler an action is, the more complex it is in our brains to accomplish it. Consciousness is actually detrimental to a lot of simple actions.
Here is a story: There was a centipede with 300 legs walking around, until a bug walked by and said, "Wow! How do you walk with so many legs! Which one goes in front of the other?" The centipede stopped and thought about it and couldn't explain it. When he tried to walk he fell over and couldn't move. He forgot how to coordinate his movements.
This is an example of "muscle" memory. Some functions are so essential to our survival that they become instinct and are hardwired into our brains.
I would think an intelligent being would not be so different in mental capability to ourselves, although thought process is probably very different. They wouldn't have to worry about instinctual behaviors (these are what robots are good at btw), and they probably stopped evolving once they reached the intelligence level to do basic hunter/gather stuff. Evolution in a society like that would take a looong time, and by the time their intelligence or brain structure could change they would have already become advanced enough to take control over biology with technology.
Maybe I'm wrong but I think any other form of intelligence is probably only able to be so different than us or it risks not being able to function properly to develop technology in a form we could relate to.
