Nanorobot, computer artwork. Nanorobots is a term used to describe future microscopic robots that could have a wide range of uses, from medical to industrial. Their design may be based on existing designs, such as that of insects, or the designs may be completely new. This nanorobot is capable of hovering in mid-air. The spikes may be designed to perform an offensive function. Military use may be among the first applications of nanotechnology.
