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.

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.

The ideal vacuum cleaner would be one you never see. It needs to not just be a cool gadget, but a product that cleans your floor correctly. I can imagine people having a cupboard full of robots that only come out when you need them to fulfil a specific 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.

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

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.
