Postman, shopper, builder: In Japan, there's a robot for that

TOKYO - Forget the flashy humanoids with their gymnastics skills: at the World Robot Summit in Tokyo, the focus was on down-to-earth robots that can deliver post, do the shopping and build a house.

Introducing CarriRo, a delivery robot shaped a bit like a toy London bus with bright, friendly "eyes" on its front that can zip around the streets delivering packages at 6km/h.

CarriRo "is designed to roll along the pavements and direct itself via GPS to an address within a two-kilometre radius," explained Chio Ishikawa, from Sumitomo Corp, which is promoting the robot.

The lucky recipient of the package is sent a code to a smartphone allowing him or her to access CarriRo's innards and retrieve whatever is inside -- post, medicine or a take-away.

Services like this are especially needed in ageing Japan. With nearly 28 percent of the population over 65, mobility is increasingly limited and the country is struggling for working-age employees.

Omron showcased a robot that can be programmed to glide around a supermarket and place various items into a basket. Possibly useful for a lazy -- or infirm -- shopper but more likely to be put to use in a logistics warehouse.

Japan also has difficulty finding staff to stack shelves at its 55,000 convenience stores open 24/7 and here too, robots can fill the gap.

With buildings going up at breakneck pace as Tokyo prepares to welcome the world for the 2020 Olympics, there are construction sites all over the city but not always enough people to work them.

Enter HRP-5P. The snappily named, humanoid-shaped machine certainly has the look of a brawny builder, at 182cm tall and weighing in at 101 kilogrammes.

And HRP-5P is designed to carry out the same construction tasks that humans currently perform -- even when left to its own devices.

Sharp's Robohon, a cute-as-pie humanoid robot standing only 20 centimetres tall, has been employed since last month to recount to tourists the history of the ancient Imperial capital of Kyoto -- in English, Japanese or Chinese. 

And very popular among Japanese visitors to the World Robot Summit was a robot replica of Tetsuko Kuroyanagi, one of the country's top TV stars.
