And we made, back in about 1985 or 6, I can't remember, we had a simple robot doing somersaults. To do it in 3D, really the calculation is the same. You just have to be balancing in the other degrees of freedom. If you're just doing a somersault, it's just a planar thing.

When Rob was my graduate student and we were at MIT, which is when we made a two-legged robot do a 3D somersault for the first time. There, in order to get enough rotation rate, you needed to do tucking also. You know, withdraw the legs in order to accelerate it. And he did some really fascinating work on how you stabilize more complicated maneuvers.

You remember he was a gymnast, a champion gymnast before he'd come to me. So he had the physical abilities. And he was an engineer, so he could translate some of that into the math and the algorithms that you need to do that.

Unfortunately, though, humans don't really know how they do it, right? We're coached. We have ways of learning, but do we really understand in a physics way what we're doing? Probably most gymnasts and athletes don't know.

Atlas still doesn't walk like a person, and it still doesn't walk quite as gracefully as a person, even though it's been getting closer and closer. The running might be close to a human, but the walking is still a challenge.

And something weird about the knee, that you can kind of do this folding and unfolding, And get it to work out just, a human can get it to work out just right. There's compliances. Compliance means springiness in the design that are important to how it all works. Well, we used to have a motto at Boston Dynamics in the early days, which was, you have to run before you can walk.

For a quadruped, probably. Of course, it was probably the loudest, too. So we had this little racing go-kart engine on it, and we would get people from three buildings away sending us, complaining about how loud it was.
