Programming expert Rongzhong Li has designed a complex 3D printable robotic cat equipped with artificial intelligence and numerous cool features. The fake feline, which contains an Arduino Pro Mini and a Raspberry Pi 3 Model B, has a "Super Hard" classification on hackster.io. Robotic pets have long fascinated the consumer market, with toys like the Sony AIBO enjoying big success. In fact, the legendary AIBO is now back after an 11-year hiatus, to the delight of many. Unfortunately, it comes with a $1,800 price tag.

Sony's newest push into robotics is a dog. And while it's primarily intended to be a toy, it has the makings of an adorable pet and the artificial intelligence capabilities of a bot. So all in all, Sony's pet dog "Aibo" is a toy, a pet and a robot in one. By introducing Aibo at CES 2018, Sony resurrected the robot dog line that was all the rage back in the late '90s to early 2000s. The mutt-looking gadget absolutely stands out among the products and inventions showcased at the Las Vegas trade show for all the right reasons.

Sony revived its robodog series late last year, offering a limited first run of next-generation Aibos for keen Japanese fans. Despite a killer $1,800 price-tag, the company apparently sold plenty, and those preordered Aibos are finally on their way to their new owners. Finally, the company has brought the new robotic pet out of Japan, and while I could coo in Aibo's general direction, unfortunately no petting was allowed. Regardless, it was disarmingly cute. The dog dunderstood a handful of English-language directions, including hand-shaking and commands to sit.

Sony has resurrected Aibo, the robot dog it stopped selling back in 2006. The electronic, internet-connected pet has been updated with modern components and been given a brand new look, which the company describes as "adorable" and "irresistible". It's autonomous, meaning it can wander around your home on its own, and Sony says it can "develop its own unique personality" and also show "love and affection". It measures 180 293 305mm, weighs approximately 2.2kg and has a battery that lasts for two hours. The dog takes three hours to charge back up again when it runs flat. Sony says it loves the colour pink and can learn new tricks, but dislikes heights and tight spaces.
