Tesla CEO Elon Musk showcased his much-touted humanoid robot “Optimus” at the electric vehicle maker’s “AI Day” event on Friday. The billionaire has said a robot business will be worth more than its cars, hoping to expand beyond self-driving vehicles that have not yet become a reality despite his repeated promises. A prototype of the robot walked on stage and waved to the seated audience. A video of the robot carrying a box, watering plants and moving metal bars in the automaker’s factory was shown.
