When we built Roomba, we explicitly designed it to not have a face. We didn't want to think it was cute, we wanted people to take it seriously so we gave it more of an industrial look. People personified their Roomba anyway. Over 80 percent of people name their robot. We did nothing to encourage people to do that but they do it anyway.

There are so many opportunities to make a bad decision in building a robot company on top of all the normal ways that entrepreneurs screw up that it is incredibly difficult to truly create value because it is so cost-sensitive.

The answer is navigation, manipulation, and implementation of more sophisticated intelligence. The idea that a robot will become more aware of its environment, that telling it to "go to the kitchen" means something - navigation and understanding of the environment is a robot problem. Those are the technological frontiers of the robotics industry.

I was focused on building things from an early age. When I was about 3, our toilet broke, and my mother was ready to call the plumber. I told her I would fix it and asked her to get my Richard Scarry book 'How Things Work in Busytown.' Between the picture of a toilet and the text she read to me explaining how the parts worked, I fixed it.

The reason it has taken so long for the robotics industry to move forward is because people keep trying to make something that is cool but difficult to achieve rather than trying to find solutions to actual human problems. Technology can be extremely expensive if you don't focus.

"Star Wars" was the right movie for me. I watched the MSE-6 droid leading the stormtroopers where they needed to go when they were under attack, and that got my attention much more so than C-3PO and R2-D2 because we could actually build that.

The way that the robotics market is going to grow, at least in the home, is that we'll have a number of different special purpose robots.
