We've already seen several dog-like quadruped robots, which move by walking with their four backward-bending legs. Researchers at Florida Atlantic University are now getting in on the act, with their artificially-intelligent (and dog-headed) Astro robot. First of all, Astro's style of locomotion is intended to be more than just an attention-getter. Like the other robo-dogs that are on the market or in development, it's able to withstand attempts at knocking it over, plus it's well-suited to traversing rough terrain – such as it might encounter in search-and-rescue operations, or when surveying disaster sites. What reportedly makes Astro special, however, is the set of Nvidia Jetson TX2 graphics processing units contained within its 3D-printed, Doberman pinscher-inspired head.

A 3D-printed head can trick your smartphone's facial recognition technology into unlocking your phone. Experts showed that Android's models were the least secure, with some devices opening by simply showing a photograph of the owner. It was found that Apple, who got rid of its finger print reading ID in favour of facial recognition last year, was the most secure when tested. The findings bring up concerns over offering hackers and police an entry route into your personal information stored on your handset. A test conducted by Forbes magazine showed that Android's models were the least secure, with some devices opening by simply showing it a photograph of the owner.
