lifelike or elegant or just natural looking.
And so I think if you get the physics right, it also ends up being more efficient, likely.
There's a benefit that it probably ends up being more stable in the long run.
You know, it could walk stably over a wider range of conditions.
And it's more beautiful and attractive at the same time.
And it had a really nice looking gate where it would stick the leg out, it would do heel strike first before it rolled onto the toe so you didn't land with a flat foot, you extended your leg a little bit.
But even then, it was hard to get the robot to walk when you were walking that it fully extended its leg and essentially landed on an extended leg.
And if you watch closely how you walk,
you probably land on an extended leg, but then you immediately flex your knee as you start to make that contact.
And getting that all to work well took such a long time.
In fact,
I probably didn't really see the nice natural walking that I expected out of our humanoids until maybe last year.
And the team was developing on our newer generation of Atlas some new techniques for developing a walking control algorithm.
And they got that natural looking motion as sort of a byproduct of just a different process they were applying to developing the control.
So that probably took 15 years, 10 to 15 years to sort of get that from, you know, the Petman prototype was probably in 2008.
And what was it?
2022.
Last year that I think I saw a good walking on Atlas.
Yeah, so one of the things that makes this straight leg a challenge is you're sort of up against a singularity, a mathematical singularity, where when your leg is fully extended, it can't go further the other direction, right?
You can only move in one direction.
