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.

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

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.

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.

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.
