Many highly intelligent humans predict highly intelligent robots as soon as researchers find the programming and/or hardware to make it work. Theories about the technological singularity, the point at which artificial intelligence surpasses human intelligence, are supported by notable figures such as Ray Kurzweil and Vernor Vinge. It's a very attractive advancement, one in which intelligent systems can help move humanity forward faster than we ourselves are capable of managing. Coupling artificial intelligence with robotics would provide devices capable of not only responding to human need, but identifying human need in real time or even in advance of the need - and not only based on human trends, but on the needs of an individual human.
As an aside, we should also note the Terminator series turns artificial intelligence into Skynet and nearly indestructible robots with time travel capabilities. A far cry from helpful butler-bots, life-saving surgical-bots, and wiggly sex-bots.
