Musk cautioned however it still had a way to go before becoming fully functional

Musk said current humanoid robots are 'missing a brain'

"They don’t have the intelligence to navigate the world by themselves and they’re also very expensive and made in low volume, whereas Optimus is designed to be an extremely capable robot but made in very high volume, probably ultimately millions of units and it’s expected to cost much less than a car."

The robots are expected to come with a price tag of under $20,000
