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 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.

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.

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.

Its going to be interesting to see how society deals with artificial intelligence, but it will definitely be cool.

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.

One of the big things coming out of healthcare reform is a thing called the Community Living Assistance Services and Supports Act (CLASS) which is a mechanism to reimburse people staying at home for technology and services that allow them to stay at home.

That's exciting because to create new value in the robot space quickly, you need to stand on the shoulders of other technological developments.

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.

In the original 'Star Wars' movie, there is a small toaster-sized and shaped robot on the Death Star that guides Stormtroopers to where they need to go. I always liked that robot because I could imagine how to build it - and it served a real purpose.

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

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.

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.

We learned that very few people care how you accomplish something. Instead, these people care more about whether you create value for your end user.

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.
