Auto manufacturers, for example, are trying to use tiny devices that can sense when to release an airbag and how to keep engines and breaks operating efficiently. Some futurists envision nanotechnology also being used to explore the deep sea in small submarine, or even to launch finger-sized rockets packed with micro miniature instruments.
There is an explosion of new ideas and applications, So, when scientists now think about future machines doing large and complex tasks, they’re thinking smaller than ever before.
