Human-like .. Elon Musk presents the famous "Optimus" robot

 Tesla CEO Elon Musk showcased his famous humanoid robot Optimus during the 'Artificial Intelligence Day' event organized by the electric car manufacturer, on Friday. The billionaire said that the robotics business will be more valuable than cars, hoping to expand beyond self-driving cars that have not yet become a reality despite repeated promises about them.

A prototype of the robot walked on stage and waved to the spectators. A video clip of the robot was shown carrying a crate, watering plants and moving rods at the car manufacturer's factory. "Our goal is to make a useful human-like robot as quickly as possible," Musk said at the event, which was held at Tesla's office in Palo Alto, California. "There is still a lot of work to be done to improve and prove Optimus."

Musk said humanoid robots currently "lack a brain, don't have the intelligence to roam the world on their own, are expensive and are made in low quantities."

By contrast, he said, the Optimus would be a "very good robot" that would be manufactured in very large quantities, perhaps millions of units eventually, and was expected to cost much less than a car or less than twenty thousand dollars. In the future, Musk said, robots could be used in homes, prepare dinners, mow the lawn, care for the elderly, and even become companions for humans.
