It took a few iterations of the software and the machine to come up with a solution to some of the spinning turns used in the ballet parts, since they were so far removed from leaping and running and the other things that are more familiar to us, so they posed a challenge for the software and the machine. Dancers, on the other hand, are definitely flexible and strong, and if you try to do the same thing they do with a robot, it turns out to be a very difficult challenge. We definitely learned not to underestimate their flexibility. It's a very humbling experience. My fundamental opinion is that Atlas does not have the same range of motion or the same power that these athletes do, but we are continuing to develop our robots in this direction, as we believe these kinds of robots must have a performance level that is comparable to that of these athletes to be widely deployed commercially, and eventually in homes. A robot is very good at one thing: doing something over and over again in exactly the same way, over and over again. After we had dialed in exactly what we wanted to do, the robots were able to just repeat the process over and over again as we experimented with different camera angles and settings.
