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.

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 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.

Hollywood likes to imagine robots as mechanical copies of ourselves - which is a terrible idea.

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

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.

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.
