SAN FRANCISCO (Reuters) -Tesla CEO Elon Musk showed off on Friday a prototype of its humanoid robot 'Optimus', predicting the electric vehicle maker would be able to produce millions and sell them for under $20,000 - less than a third of the price of a Model Y.

Musk said he expected Tesla would be ready to take orders for the robot in three to five years, and described an effort to develop the product over a decade or more, the most detailed vision he has provided to date on a business he has said could be bigger than Tesla's EV revenue.
