How much will Elon Musk robot cost?

Excuse me, could you please clarify the question about the cost of Elon Musk's robot? It's worth noting that Elon Musk, being a visionary entrepreneur and CEO of several companies, including Tesla and SpaceX, hasn't publicly announced any specific robot project with a predetermined cost. However, if you're referring to any of his companies' potential robotic ventures or products, the cost would depend on various factors, such as the complexity of the technology, production scale, and target market. Could you provide more context or specify which robot you're referring to? It would help me give you a more accurate answer.
