Did Google need to make robot cars in order to make Streetview work? Absolutely not. It's the equivalent of saying you need a walking robot in order to push an upright vacuum cleaner. It's gratuitous robotics!

What did everyone think robot vacuuming was going to be? Well, they think Rosie the Robot from 'The Jetsons,' a human robot that pushed a vacuum. That was never going to happen.

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.

We are not out there as a vacuum cleaner, ... We don't have that capability and we don't want that capability.

I thought boxes were the best toy. When my parents got a new car, I ran to my mother and said, 'Did it come in a box?'

Building a robot that has legs and walks around is a very expensive proposition. Mother Nature has created many wonderful things, but one thing we do have that nature doesn't is the wheel, a continuous rotating joint, and tracks, so we need to make use of inventions to make things simpler.
