Online giant Google is all about robots these days. They’ve purchased seven in total, including Boston Dynamics, smart appliance producer Nest, and Meka, which makes humanoid robots. Now, they’re interested in making those robots a little less, well, robotic. Google announced the purchase of DeepMind, a UK artificial intelligence firm that aims to make machines behave more like humans. Estimates on the value of the deal range from $400 – $500 million.

The DeepMind website states: “We combine the best techniques from machine learning and systems neuroscience to build powerful general-purpose learning algorithms. Our first commercial applications are in simulations, e-commerce and games.”

Google is keeping quiet as to their intentions for all of these robotics, but evidence points to plans for creating artificially intelligent robots and machines for the home. Others speculate that it might lead up to an automated transportation network. Perhaps in anticipation of public backlash, or perhaps because of a genuine need, Google has reportedly created an ethics board in partnership with DeepMind to avoid abuse of the powerful artificial intelligence.

Though the structure is unclear, The Information reports that the board was requested by DeepMind as part of the merger.

Google’s products are already plenty smart on their own. Their “Hummingbird” search update was designed to understand search terms in context, much like the human brain. The Google app for Android reportedly uses “predictive analysis” to determine what users will do next and offer unsolicited help and information. With DeepMind, whose technology has been used in demonstrations where computers play video games very much like humans, Google is one step closer to further blurring the line between man and machine.

DeepMind was founded by neuroscientist Demis Hassabis, along with AI experts Shane Legg and Mustafa Suleyman. Those talent acquisitions lead the LA Times to speculate that Google might be as interested in DeepMind’s human brains as they are their artificial ones. Re/Code reports that DeepMind had been recruiting heavily in the AI space, taking talent from companies like Google and Facebook, who Google apparently edged out for the acquisition.
