Tesla says it is building a ‘friendly’ robot that will perform menial tasks, won’t fight back

Tesla previewed the robot concept at a presentation at its Fremont, Calif., factory Thursday, calling it the “Tesla Bot” and “Optimus,” and said it would show a prototype next year. As part of the presentation, a human dressed as the machine made robotic gestures and then danced onstage, perhaps demonstrating the range of motion that Tesla hopes the bot could achieve. Musk was quick to clarify that the dancer was not a real robot.
