 In the Tesla Investor Day presentation on March 1, 2023, they showed the video of two robots walking and doing assembly work. Tesla has been sharing design specifications of the robot that they call Optimus. Optimus will be 5 feet 8 inches tall, 160 pounds and will be able to walk 5 miles per hour. Optimus can carry 45 pounds when walking and can lift 150 pounds when it is stationary. Optimus will have conversational capabilities. According to Elon Musk, Optimus will eventually cost less than $20,000, although the introductory price will be much higher than that. Optimus will be available to the customers in 3 to 5 years. Elon Musk said that robots will be a bigger business than cars for Tesla in the future. Elon said universal income will be needed. That means humans will get paid for not working because most of the physical work will be done by robots and other means of automation.
