Robots

No discussion of cool tech in Japan would be complete without robots. Japanese researchers are leading the world in robot technology, and humanoid bots like Honda's Asimo are especially impressive.

The latest version of Asimo can serve drinks on a tray and has gained the ability to work intelligently with other Asimo robots in the vicinity to get jobs done faster. Two of the robots have spent most of January working at Honda's Tokyo offices, bringing tea or coffee to guests--and almost certainly entertaining the visitors at the same time.

Rival car-maker Toyota has a clutch of robots including one unveiled in December that plays the violin. (It follows a trumpet-playing robot created a year earlier, so perhaps a robot orchestra is in the making?) The company also has Robina, which is intended to serve as a guide in a public space. Toyota put it into use last year at a public hall in Japan and expects robots like Robina will be commercially realistic in the middle of the next decade.

Taking on a much more serious role is Twendy One, a home-help robot developed by Tokyo's Waseda University. It can do many of the basic tasks that a frail person may need help with, such as assisting people out of bed and serving up toast and drinks.

The robot is still under development but could have a bright future. Japan's population is aging fast--already, 22 percent of people are over 65--and the birth rate is slowing. That likely means a future shortage of workers. It's one of the reasons money is being poured into robot technology in this already technology-saturated nation.
