• Tesla's long-anticipated AI robot made its official debut by dancing and waving on stage at the company's AI Day.

• "The robot can actually do a lot more than we showed you. We just didn't want it to fall on its face," Elon Musk said.

• At last year's AI Day, Musk announced his plans for the bot by having a human in a robot costume dance onstage.

Tesla's long-anticipated AI humanoid robot, Optimus, made its public debut on Friday night at the company's AI Day.

The bot, which is currently only a "rough prototype," according to Tesla, waved and slowly danced for the crowd on stage during the event.

"The robot can actually do a lot more than we showed you. We just didn't want it to fall on its face," Tesla CEO Elon Musk told the crowd.
