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

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.

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

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.

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.

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.'
