When I was building robots in the early 1990s, the problems of voice recognition, image understanding, VOIP, even touchscreen technologies - these were robotics problems.

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.

I was focused on building things from an early age. When I was about 3, our toilet broke, and my mother was ready to call the plumber. I told her I would fix it and asked her to get my Richard Scarry book 'How Things Work in Busytown.' Between the picture of a toilet and the text she read to me explaining how the parts worked, I fixed it.

Doolittle was a major influence on the Seattle grunge scene, which emerged in the early 1990s.

We're in the very early stages of both understanding the technologies and trying to understand from our customers' perspective what they would like to see.

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.
