I was training more learning how to scuba dive which I'd never done which was really, really, really cool.

Not being a comic book fan, being thrown into that and seeing the extreme - it's taken very seriously. So I tried to do as much learning as I could about it so I wasn't mean or anything.

You have to keep your sanity as well as know how to distance yourself from it while still holding onto the reins tightly. That is a very difficult thing to do, but I'm learning.

I had been impressed by the fact that biological systems were based on molecular machines and that we were learning to design and build these sorts of things.

We wanted to solve robot problems and needed some vision, action, reasoning, planning, and so forth. We even used some structural learning, such as was being explored by Patrick Winston.
