Elon Musk and Tesla to unveil humanoid robot: 5 things to know

Why is Musk building a robot? Musk teased the idea of the Tesla Bot at the first AI Day last year, CNET reported. He provided details on specifications and showed a mockup to guests, including someone who came out wearing an Optimus outfit and danced around to show how the robot would move, but Musk chose to wait until the second AI Day to present a physical prototype. According to Musk, the robot will be designed to handle "dangerous, repetitive, boring tasks" a human would want to avoid. "In the future, physical work will be a choice. If you want to do it, you can, but you won't need to do it," he said at the event.
