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.'

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.

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.

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.

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.

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