Sanja Suljagic speaks to Dr Edmund Ronald about Japanese robotics.

In this time of technological revolutions, computers have popped up everywhere - homes, the workplace and even hair salons. More and more people are becoming curious about new technology, and as a result, robots have also increased in popularity. From mechanical pets to automatons that look and act like humans, experts from around the world are creating 'bots that not only look cool and provide entertainment, but are useful in all areas of human existence. Dr Edmund Ronald, a visiting researcher at the Swiss Federal Institute of Technology, is a robotics expert that is well aware of the leaps and bounds made in his field worldwide. TC asked Dr Ronald to relay some of his opinions on the status of Japanese robotics today, technically speaking.

Do you see any difference in your field between Japan and the rest of the world?
Japan has much better and cheaper technology. Japanese firms (Sony, Bandai, etc.) are bringing out entertainment robots today, selling dancing dolls, prancing dogs and crawling bugs to kids in the mall. On the other hand, in Europe, we do a lot of theoretical work on future self-reproducing systems and artificial life. And in the US, in the past, work was often military-funded and the goal was to send robots into dangerous environments - like space - or outright hostile situations like a future battlefield.

So, Japanese robots are friendly and playful?
That's right. Japanese researchers view every interaction as a social interaction. While in the West a robot was often conceived as a tool with a claw, in Japan researchers emphasize the personality of their robots. You can see this trend with mobile phones, which greet their users with a winking cartoon face when turned on, so people will trust these new devices with their pleasant, friendly faces and allow them into their homes. Today, a kid plays with its Aibo. But tomorrow, the parents will notice the built-in TV camera and optional wireless link, which could send pictures to them at work, via the Internet, and reassure them about their offspring's well-being. Putting a nice face on the technology makes it socially acceptable and creates a market for it.

What fascinates you about Japanese robots?
The originality and variety of the work, as well as its technical excellence fascinates me. The walking robots created by the Honda Corporation and Waseda University are technically amazing. I have also seen the Flute Playing Robot at Professor Takanishi's lab at Waseda, a robot that plays on a real Yamaha flute, with air blown from mechanical bellows through flexible lips. There is also a robot set of jaws that can chew on food and evaluate its texture, as well as a face that will blush when smoke is blown up its artificial nostrils. You'll see some far out stuff in the States too, but I'd say the robots here are more fun!

What is the future vision driving Japanese robotics?
It is that of a caring society, where a multitude of robots will help the elderly in a variety of day-to-day situations - from the simplest physical assistance for getting out of bed, to teleoperated medical procedures. Robots in Japan are being invented to help humans here on planet Earth, although I have a feeling that the entertainment industry will reap the actual short-term economic benefits.
