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.

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

In the end, robots do things that people can do. So there is a cost above which you can hire somebody to do it, and that bounds the opportunity.

I think, people are generally willing to imagine robots of all shapes, as humanoid robots are not practical.

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

My very clear vision for the ideal Roomba is one you never see and you never touch. Our research priorities are explicitly focused on the Roomba of the future that will deliver on the promise of automatically cleaning your floor.

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.
