Of Artificial Intelligence, Robotics, Chaos and Universe

Thus far US and Japan are the leading countries in terms of Robot engineering, and I believe the latter is more commercially successful than technologically advanced compared to the US.
Japan has created a lot of commercial robots, ready to serve mankind. There's this mecha receptionist, which spot some of the most advanced technologies like voice recognition, facial recognition, emotion simulation, comprehension engine, etc. In other words, it can understand you. Not that it really understands you, but it is made in such a way that it convinces you of its genuinility as "human". It tries to decieve you.
Without proper instructions to guide them, they can't work. When we've finally moved out of that menial heavy industry era, so to speak (because most of the jobs are specific and repeatitous), we talk about smarter machines. The need for smarter machines arises because when they stumble upon simple obstructions, they can't analyze the situation and make a plan to go around it. Such, again menial jobs, still need the intervention of Human beings.
That's part of the reason we try to create Artificial Intelligence. Another reason would be that it's a delicious challenge, as there are no other entity in this universe that is capable of creating existence and intelligence except the all-mighty god, as some of you may believe. To actually create the underlying mathematical formulae that'll power this articial intelligence is not of without difficulties. Humans, for the very first time, started to be humble.
For centuries human takes pride of themselves for the ability to understand and solve the most complex problems ever conceived (or is it human themselves that complicate matters? Heck they can even create the math formula that draw out a fern's image. But can you see how simple a fern is? It's just a plant!) So why do we still stuck with this artificial intelligence? That's because we never understand ourselves.
Artificial Intelligence may or may not requires cognitive abilities, consciousness, self-awareness and free-will ability. Thus far it is only mathematical models. That means such product of it is always predictable. we can blurt out random stuffs easily, but not with machines. Machines are logical devices, so they can never produce true random numbers. Ironic, it seems, that patterns always arise from chaos and randomness (the chaos theory?). So does that mean that if we're given enough physical information of the earliest times of the universe, we'll be able to predict pathways of particles and waves, space and time, which eventually leads to prediction of events, or even tracking back particles' journey and from there we can paint a picture of what had happened before? No, it seems, for the uncertainty principle dictates so. We can't observe the velocity and exact position of a particle at the same time. Observing one will most likely affect the other. Because we're using the very materials that fabricate this universe to peek into the graininess of the universe. The photons or any minute particles may interfere with the particle that we're observing.
When I come to think that we humans are merely carbons, hydrogens, oxygens, nitrogens and all sorts of elements and particles got stucked together that collectively create the correctly ordered hierarchy of organels, cells, tissues, organs, systems and finally a complete body, it struck me that we humans are also robots, only that we are not made of metal. We, or our body, including the neurons that depicts our consciousness, may work based on a mathemetical formula, that ultimately, only God knows (it also occur to me that we may be computer simulations in a lab by aliens, to study the complex social structures amongst the homo sapiens species itself). So if we as robotic organisms can understand the meaning of existence and possess cognitive abilities and most importantly, freewill, might it not that one day we can achieve that too, albeit with bolts and nuts?
