Search engine giant Google has a clandestine research and development division which is working on advanced robotics and other futuristic technology.
According to The New York Times, Google has its own secret research program called Google X, whose existence is not known to a majority of Google employees.
Google X has two offices, one located in its Mountain View HQ, used for logistics, while the other, whose location is unknown to many, deals with robotic and artificial intelligence research.
Google co-founders Sergey Brin and Larry Page are actively involved in the project and so is former CEO and now executive chairman Eric Schmidt including other senior level executives.
Google X is strewn with former Microsoft, Nokia Labs employees while others have been recruited directly from Stanford, M.I.T., Carnegie Mellon and New York University.
The secret division also employees some of the most notable names in the field of advanced robotics and artificial intelligence including Sebastian Thrun, Andrew Ng and Johnny Chung Lee.
Many products thought off and designed in Google X may not see the light of day but the division keeps Google's innovative spirit alive and kicking.
