Not really -- in fact, some of the ways we design and manufacture our components, such as 3-D printing, are very high-tech. But we do work with a bottom-up approach. We are in the stage that each robot has a specific task, and we design something for that task. This is the art of science, to take a complex task and break it into small pieces that are easier to handle, then combine them together. Simple is good in general. The greatest inventions are the simplest ones -- like the wheel, for instance.
