Building robot versions of people is very expensive.

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

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.

Building robot versions of people is very expensive.

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.

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.
