Robot DOG makes an appearance at the Met Gala - dressed in a tuxedo and adorned with a 1,000-carat diamond leash

At New York's Met Gala, guests are known for attention-grabbing outfits, from Katy Perry's human chandelier dress to Kim Kardashian's all-black body suit. But one attendant in particular has stolen the limelight this year – and he's not even human. Indian-American entrepreneur Mona Patel rocked up to the annual event on Monday night with an adorable robotic dachshund in tow. Vector the robo-dog, developed by scientists at MIT, has a 1,000-carat diamond-studded leash and his own cute little specially-fitted tuxedo. Powered by AI and equipped with sensors, Vector has customised movement patterns and'just the right amount of sass', Vogue India reports.
