Elon Musk says 'epic' Tesla robot will be unveiled at AI event

Tesla will unveil a prototype of its Optimus robot in September, Elon Musk has revealed. The Tesla CEO said the company's AI Day would be delayed in order to debut the humanoid robot, which the billionaire has claimed could be "more significant" than the company's electric car business. "Tesla AI Day pushed to Sept 30, as we may have an Optimus prototype working by then," Mr Musk tweeted. "Tesla AI Day 2 will be epic." The Optimus robot was first teased last August at Tesla's inaugural AI event, with Mr Musk saying it would have "profound implications for the economy".
