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.

Building robot versions of people is very expensive.

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

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.

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.'

Around the late 1990s, I'd become convinced that one of the killer applications of robotics came from connecting robots to the Internet. The idea of solving generalized artificial intelligence was still far away, but heck, I could rent brains by hiring operators. iRobot was the name of the company and one of our most ambitious projects, iRobot LE.

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.
