A cooing, gesturing humanoid on wheels that can decipher emotions has been unveiled in Japan by billionaire Masayoshi Son who says robots should be tender and make people smile.
Son's mobile phone company Softbank said that the robot it has dubbed Pepper will go on sale in Japan in February for 198,000 yen. Overseas sales plans are under consideration but undecided.
The machine, which has no legs, but has gently gesticulating hands appeared on a stage in a Tokyo suburb, cooing and humming. It dramatically touched hands with Son in a Genesis or ET moment.
Son, who told the crowd that his longtime dream was to go into the personal robot business, said Pepper has been programmed to read the emotions of people around it by recognising expressions and voice tones.
"Our aim is to develop affectionate robots that can make people smile," he said.
Cuddly robots are not new in Japan, a nation dominated by "kawaii," or cute culture, but no companion robot has emerged a major market success yet.
Japanese electronics and entertainment company Sony discontinued the Aibo pet-dog robot in 2006, despite an outcry from its fans. At that time, Sony had developed a child-shaped entertainment robot similar to Pepper but much smaller, capable of dances and other charming moves, which never became a commercial product.
Honda has developed the walking, talking Asimo robot, but that is too sophisticated and expensive for home use, and appears in Honda showrooms and gala events only. Even then, it is prone to glitches because of its complexity.
Many other Japanese companies, including Hitachi and Toyota, not to mention universities and startups, have developed various robots, big and small, which entertain and serve as companions.
There is little emphasis on delivering on practical work, in contrast to industrial robots at factories and military robots for war.
But the potential is great for intelligent machines as the number of elderly requiring care is expected to soar in rapidly-aging Japan in coming years. Robotic technology is already used to check on the elderly and monitor their health and safety, but robots might also play a role in reducing feelings of loneliness and isolation.
The 121 centimetre tall, 28 kilogram white Pepper, which has no hair but two large doll-like eyes and a flat-panel display stuck on its chest, was developed jointly with Aldebaran Robotics, which produces autonomous humanoid robots.
Besides featuring the latest voice recognition, Pepper is loaded with more than a dozen sensors, including two touch sensors in its hands, three touch sensors on its head, and six laser sensors and three bumper sensors in its base.
Pepper can get information from cloud-based databases and comes with safety features to avoid crashes and falls, and its capabilities can grow by installing more robot applications, according to Softbank.
It also has two cameras and four microphones on its head and has Wi-Fi and Ethernet networking capabilities.
In this week's demonstration, Pepper sang, "I want to be loved."
Softbank said Pepper can dance and tell jokes. The machine will be on display starting Friday at Softbank retailers.
