The South Yorkshire professor claims human-like robots will be so like-life, we won't even spot them!
Sheffield University's Prof Noel Sharkey says the complete society integration will involve shop assistants and bar staff but also potentially "deceitful" doctors and care workers.
The robotics authority's alert comes ahead of tonight's premiere of TV's latest re-imagining of a futuristic fantasy wild west park.
Start of Westworld, produced by JJ Abrams - the man behind Star Wars: The Force Awakens, Star Trek and Cloverfield - will confirm robot supreme being fears.
The academic, emeritus professor of AI and robotics at University of Sheffield, warned: “The robotics community has certainly been considering the idea robots will be walking among us. It is just a matter of when really.
"We are likely to see robots integrated into society in the near future as shop assistants, receptionists, doctors, bar tenders and also as carers for our elderly and children.
"I think it'll all happen very gradually over the next 20-30 years until we don't even notice they're among us".
He continued: ""The way we're first going to see robots integrated into society in the near future will be as shop assistants, bar tenders and also as carers for our elderly and children.
"I don't think there's anything to be concerned about but if they come to look too human-like then they could be used to deceive us in many, many ways."
Britons remain terrified of being enveloped by a dystopian future in which robots take complete control of society, research reveals.
More than a third of us fear rise of artificial intelligence could lead to robots evolving beyond our own understanding to take over.
And around 40 per cent think so-called humanoids could eventually destroy humanity as we know it, concerns echoed by Professor Stephen Hawking and Elon Musk, founder of SpaceX programme who previously described AI as "mankind's biggest existential threat".
One in seven of us think we will encounter human-like robots on a day-to-day basis within a decade while two thirds expect this to be the norm within 50 years.
Men are almost twice as likely as women to relish living among androids but Britons in general are most worried about what impact robots could have in the way they interact with children, followed by worries of losing jobs to super-efficient humanoids.
