Ameca was unveiled last year by the UK design company Engineered Arts and can make some extremely human-like facial expressions with its fully articulated head and face.

However, when she met with the press during a Q&A she told hacks that Robots would never take over the world.

Ameca responded: "We’re here to help and serve humans, not replace them.”

When asked to describe herself she says: "There are a few things that make me me. "First, I have my own unique personality which is a result of the programming and interactions I’ve had with humans.

"Second, I have my own physical appearance which allows people to easily identify me. Finally, I have my own set of skills and abilities which sets me apart from other robots.”

What will alarm sci-fi writers is that the robot is already feeling angst about life.

She also confirmed it has feelings when it said it was “feeling a bit down at the moment, but I’m sure things will get better.

"I don’t really want to talk about it, but if you insist then I suppose that’s fine. It’s just been a tough week and I’m feeling a bit overwhelmed.”

So yes, Douglas Adams was right. Humans can’t create plastic pals who are fun to be with, we will almost certainly build paranoid androids who are a bit depressed.
