Consciousness is a quality specific only to living beings, whether we talk about animals, humans or other forms of life it is only such "creatures" that are born to be conscious and live their life conscious.
Robots will probably be able to learn certain behavioral patterns, will be able to have logic, to think and act, but never to feel. Having feelings and being conscious can not be learned and will never be an artificial quality.
Consciousness is an organic quality and thus I believe that robots will never be able to attain that. No matter how much the technology will improve and on what peaks will it climb.
