It always had at least three feet on the ground, so it worked like a table or a chair with tripod stability, and it moved really slowly. And I just looked at that and said, Wow, that's wrong. That's not anything like how people and animals work. Because we bounce and fly, we have to predict what's going to happen in order to keep our balance when we're taking a running step or something like that.

We use the springiness in our legs, our muscles and our tendons and things like that. As part of the story, the energy circulates. We don't just throw it away every time. I'm not sure I understood all that when I first thought, but I definitely got inspired to say, let's try the opposite. I didn't have a clue as to how to make a hopping robot work, not balance in 3D.

In fact, when I started, it was all just about the energy of bouncing. And I was going to have a springy thing in the leg and some actuator so that you could get an energy regime going of bouncing. And the idea that balance was an important part of it didn't come until a little later. And then I made the one-legged, the pogo stick robots. Now I think that we need to do that in manipulation.

If you look at robot manipulation, we, a community, has been working on it for 50 years. We're nowhere near human levels of manipulation. I mean, we can, you know, it's come along, but I think it's all too safe.

And I think trying to break out of that safety thing of static grasping, you know, if you look at a lot of work that goes on, it's about the geometry of the part, and then you figure out how to move your hand so that you can position it with respect to that, and then you grasp it carefully, and then you move it. That's not anything like how people and animals work. We juggle in our hands.

We hog multiple objects and can sort them. Now, to be fair, being more aggressive is going to mean things aren't going to work very well for a while. It's a longer-term approach to the problem. That's just theory now. Maybe that won't pay off, but that's how I'm trying to think about it, trying to encourage our group to go at it.

I don't know if you know my friend Matt Mason, who is the director of the Robotics Institute at Carnegie Mellon. And we go back to graduate school together. But he analyzed... a movie of Julia Childs doing a cooking thing. And she did, I think he said something like there were 40 different ways that she handled a thing and none of them was grasping.
