Billionaire Masayoshi Son wants to create Android for robots.

A unit of Son's SoftBank Corp. has unveiled an operating system that purports to offer a way to control robots just as Google Inc.'s software runs smartphones and tablets.

The platform, called V- Sido OS, can be customized for a wide variety of robot roles, including those used in home health care, construction and entertainment, Wataru Yoshizaki, the chief developer at Asratec Corp., said on Tuesday.
