Early last year, Andy Rubin left the position of head of the Android developers' team, the technology giant's robotics project. Then he was replaced by Sunder Pichai, the head of Chrome.
But this year Ruby finally decided to leave Google.
Mr Rubin, who has also worked for Apple, reportedly plans to found an incubator for hardware start-up firms.
Google's chief executive and co-founder Larry Page commented on Andy"s departure, "I want to wish Andy all the best with what's next. With Android he created something truly remarkable – with a billion plus happy users. Thank you."
