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.

"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.

At the World Cup, there is a constant risk that you might find a bag or some object that has been left behind, and no one is quite sure what it is. To bring in a full bomb-disposal team for each item can be very time-consuming. The PackBot can go over rough terrain, climb stairs, pick things up, and also be operated from a safe distance.

I believe one day nano-robots will play an important role in medicine.

The utility of the robot needs to come first. It's business model over technology.

I grew up mostly in Schenectady, N.Y. From an early age, building and creating things was a real passion for me.
