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

These are some of the skills new robots presented at the World Robot Summit in Tokyo can perform. From enormous'construction workers' to helpful personal shoppers, here are some of the latest breakthroughs in robotics. CarriRo, shaped like a toy London bus with friendly'eyes' on its front, delivers packages by rolling around streets at four miles per hour. It directs itself via GPS to addresses within a one-mile radius, explained Chio Ishikawa from Sumitomo Corp which is promoting the robot. The person receiving the package is sent a code to their smartphone which allows them to open up CarriRo and retrieve whatever it is delivering them.
