Clearly, Google has the capital to invest in projects totally unrelated to search.
Sorry about the title, I couldn't resist.
Over the last half-year, Google has quietly acquired seven technology companies in an effort to create a new generation of robots. And the engineer heading the effort is Andy Rubin, the man who built Google’s Android software into the world’s dominant force in smartphones.

Unlike Google’s futuristic X lab, which does research on things like driverless cars and the wearable Google Glass device, the robotics effort — moonshots aside — is meant to sell products sooner rather than later. It has not yet been decided whether the effort will be a new product group inside Google or a separate subsidiary, Mr. Rubin said.
The Google robotics group will initially be based here in Palo Alto, with an office in Japan. In addition to his acquisitions, Mr. Rubin has begun hiring roboticists and is bringing in other Google programmers to assist in the project.
