Nanomachines
Nanomachines are mechanical or electromechanical devices that are measured in nanometers, which are units of 10-9 meters or millionths of a millimeter. K. Eric Drexler popularized the idea of nanomachines in the 1980s and 1990s, with the goal of building an "assembler" nanomachine that can manipulate individual atoms to rearrange raw materials and produce useful items. The main engineering challenge is gaining control over molecular engineering and chemical synthesis to be able to position individual atoms and form new stable molecular structures like simulated nanogears.

- 2. Definition A nanomachine, also calleda nanite, is a mechanical or electromechanical device whose dimensions are measured in nanometers (millionths of a millimeter, or units of 10-9 meter). This is a representation of a nanomachine. The colored balls represent individual atoms that comprise the machine.
- 3. Visionary During the 1980’sand 1990’s, K. Eric Drexler popularized the potential for nanomachines.. The ultimate goal of nanomachine technology is to build an “assembler” nanomachine that is designed to manipulate matter at the atomic level. The “assembler” would be able to rearrange atoms from raw materials in order to produce useful items.
- 4. Engineering The most importantchallenge to overcome is one of molecular engineering. Rearranging atoms into new shapes is essentially building new molecules. Through experimentation, more control could be gained on how molecules are formed. In time, chemists will be able to position individual atoms by techniques developed in chemical synthesis. In computer simulations, molecularly stable gears and cogs have been formed through chemical synthesis. Nanogear
