Building robot versions of people is very expensive.

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

Its going to be interesting to see how society deals with artificial intelligence, but it will definitely be cool.

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 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.

I think, people are generally willing to imagine robots of all shapes, as humanoid robots are not practical.

In the end, robots do things that people can do. So there is a cost above which you can hire somebody to do it, and that bounds the opportunity.
