The prototype of "Optimus" took the stage for the first time as part of the presentation.

With techno music and disco lights playing, Optimus walked towards the audience and lifted its arms in a gesture that looked like a "raise the roof" gesture.

The first time the robot has operated without a tether was when Musk wore a black leather jacket and black pants.

Musk said that the robot could do a lot more than just wave.

He said they didn't want it to fall on its face.

The robot is doing odd jobs around the factory.

The new version of Optimus is closer to the model that will go to market. This bot was not ready to walk yet, but it has a battery pack, a control system, and an electric motor.

The robot will have opposable thumbs and be able to hold and operate tools.

The goal is to make a robot that is useful.

He wants to make them at high volume and low cost. This is what will differentiate Musk's humanoid robot from its competitors.

He said it would cost less than $20,000 to make millions of units.

It will be a fundamental transformation for civilization.

There are some fascinating moments from the court case text dump.
