Mark Rober

Like, I don't know the answer, but you know what?

I could test to find out.

So whenever we do anything, it's like...

There's so many versions that fail before you get to the final output and failing is the goal.

Like you want to break this thing.

So if I know I have to design the wheels for the Rover, you know, I'm going to make them out of three materials.

I'm going to do some analysis on a computer and then I'm going to have a bunch of different thicknesses and I'm going to test it and I'm going to smash it.

I'm going to break it because now I'm confident when I have my final answer, I know exactly why it is and the full limits of it, like what it's capable of.

What's your relationship like with failure?

I like, I embrace failure and I like, I teach that.

So in my videos, so we just did a video where he made a goalie robot that goes back and forth at like 40 miles an hour.

And then you track the soccer ball, the football, and then the goalie will move to stop the shot from going in.

And Cristiano Ronaldo tried to go against it.

And the punchline is he has no prayer.

Even from the penalty kick spot, kicking it 80 miles an hour, this thing, in the first six milliseconds, we knew where the goalie needed to be.

That means the ball goes from here.

Once it's moved an inch, we know exactly where we need to be.

How?

Because you just have three points.

We're tracking at 500 hertz.
