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.

In the beginning of Roomba, we all took turns answering the support line. Once, a woman called and explained that her robot had a defective motor. I said, 'Send it back. We'll send you a new one.' She said, 'No - I'm not sending you Rosie.'

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

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.

Hollywood likes to imagine robots as mechanical copies of ourselves - which is a terrible idea.

Building robot versions of people is very expensive.
