Last time I counted (in mid December), Google had purchased eight robotics company over the last six months. After they acquired Nest Labs for $3.2 billion in cash in the beginning of January and bought London-based DeepMind for $500 million yesterday, that makes 10. What do they plan on doing with all their assets and have they done anything lately?

According to Tech Crunch, Google's heavy investments aren't strictly tied to building a traditional robot, but more about the general pursuit of artificial intelligence. Because the company thrives on anticipating where its users will go on the internet and customizing their experience accordingly, developing computer systems more in tune with the way humans think is massively important. Being the $28 billion company they are (as estimated by Forbes in October of 2013), Google is at the forefront of this pursuit by ensuring itself the best resources and most advanced companies. (Facebook also put a bid in for DeepMind, according to Tech Crunch.)

Called the "thread" that could bind Google's other purchase together, DeepMind's technology is more focused on artificial intelligence than actual robots, according to Tech Crunch. Thus, it could help bring a universal element when applied to more traditional robotic technologies, such as the animal-modeled transport bots from Boston Dynamics, which Google purchased in December.

Perhaps anticipating a rash of visits, DeepMind's website is currently just a single page, which was also the case for Boston Dynamics when it was bought (it's since expanded back to original proportions). DeepMind's four sentence "About Us" goes:

DeepMind is a cutting edge artificial intelligence company. We combine the best techniques from machine learning and systems neuroscience to build powerful general-purpose learning algorithms.

Founded by Demis Hassabis, Shane Legg and Mustafa Suleyman, the company is based in London and supported by some of the most iconic technology entrepreneurs and investors of the past decade.

Our first commercial applications are in simulations, e-commerce and games.

As for answering the question of what Google has done with all of its purchases, it would seem the company, at this point, has more assets than actual results.
