When can you buy the Tesla robot?

Excuse me, I'm quite intrigued by the Tesla robot that has been making headlines recently. Could you kindly elaborate on when exactly one would be able to purchase this innovative product? I understand that it's still in its developmental stages, but is there any anticipated timeline for its release to the general public? Furthermore, do you have any insights on the pre-order process or any specific requirements that potential buyers might need to fulfill in order to secure their unit? I'm eager to learn more about this fascinating technology and how I can potentially become an owner of a Tesla robot.
