The female android robot, named Otonaroid, looks on during a press unveiling at Miraikan in Tokyo

In a dystopian future, the rise of our robot overlords may be far stealthier than you might expect.

Far from being Terminator-like machines, these robots could look so human that, someday, we may not be able to tell man apart from machine.

That day may still be in the distant future, but a new set of ultra-realistic robot newsreaders at a Tokyo museum reveals just how far research has developed in this area.

Named Kodomoroid and Otonaroid, the creepy-looking robots speak so smoothly they are eerily lifelike. 

Japanese robotics expert Hiroshi Ishiguro, an Osaka University professor, said they will be useful for research on how people interact with robots.

'Making androids is about exploring what it means to be human,' he told reporters Tuesday, 'examining the question of what is emotion, what is awareness, what is thinking.'

In a demonstration, the remote-controlled machines moved their lips in time to a voice-over, twitched their eyebrows, blinked and swayed their heads from side-to-side.

Powered by compressed air and servomotors, they were seated but could move their hands.

Kodomoroid read the news without stumbling once and recited complex tongue-twisters glibly.

The robots, designed with a girlish appearance, can use a variety of voices, such as a deep male voice one minute, and a squeaky girly voice the next.

The speech can be input by text, giving them perfect articulation, according to Professor Ishiguro.

There were some glitches - such as the lips not moving at all while the robot spoke, or the Otonaroid announcer robot staying silent twice when asked to introduce itself.

But glitches are common with robots because they are delicate gadgetry sensitive to their environment, said the researchers.

Kodomoroid and the woman robot Otonaroid were joined at the demonstration by the minimally designed Telenoid, a mannequin head with pointed arms that serves as a cuddly companion.

In what appeared like a scene out of 'Pinocchio', Kodomoroid asked Professor Ishiguro why he had created it. The professor replied that he wanted to create a child news announcer.

The robots, which have silicone skin and artificial muscles, will be on display from Wednesday, at Miraikan museum, or the National Museum of Emerging Science and Innovation, in Tokyo.

Reflecting widespread opinion, Professor Ishiguro said Japan leads the world in playful companion robots. But he acknowledged the nation was behind the U.S. in military robots.

'We will have more and more robots in our lives in the future,' Professor Ishiguro said.

'You can take my androids on planes - the torso in the suitcase and the head in carry-on.'

Professor Ishiguro has a humanoid version of himself which he sends overseas to give lectures.

'It cuts down on my business trips,' he said. 'Technical advances mean robots look and act more human, and that makes us think about our worth.'

His approach differs from some robotics scientists who say human appearance is pointless, perhaps creepy, and robots can look like machines, such as taking the form of a TV screen or a portable device.

Professor Ishiguro noted proudly how Japanese Internet company Softbank recently showed a robot named Pepper, which looks a little like C-3PO in 'Star Wars,' and will sell for 198,000 yen (£1,130 or $1,900).

Pepper's arrival means robots are increasingly becoming part of everyday life in Japan.

'Robots are now becoming affordable - no different from owning a laptop,' said Professor Ishiguro.

SCIENTISTS CREATE THE WORLD'S FIRST ROBOT THAT READS EMOTIONS 

In a country dominated by 'kawaii' - or cute culture - Japan has embraced the rise of cuddly robots.

Now, one Tokyo-based firm has unveiled what it believes to be the world's first droid that can read human emotions.

Mobile carrier Softbank said its robot, named Pepper, will go on sale in Japan in February for 198,000 yen (£1,130 or $1,900).

The machine, which has no legs, but has gesticulating hands appeared on a stage in a Tokyo suburb, cooing and humming. 

Pepper uses an 'emotional engine' and a cloud-based artificial intelligence to study gestures, expressions and human speech tones.

The 48-inch (121 cm) tall, 62 lb (28 kg) white Pepper has no hair, but two large doll-like eyes and a flat-panel display stuck on its chest.

It was developed jointly with Aldebaran Robotics, which designs, produces and sells autonomous humanoid robots.
