Nanorobotics involves building things at the atomic or molecular scale using programmed robotic arms. It deals with objects measured in nanometers and manipulating individual atoms. Nanorobots could potentially have medical applications like curing diseases, augmenting the immune system, and detecting pathogens in the blood. Fractal robots made of motorized cubic bricks that can rearrange themselves could be a stepping stone between conventional robots and true nanotechnology. They are less expensive to develop than molecular nanotechnology and could one day have applications in construction, mining, space, and more.

9. Features of Nanorobots
 Nanorobots can be categorized into two groups
called autonomous robots and insect robots.
 A major asset of nanorobots is that they require
very little energy to operate.
 Durability is another potential asset, may
remain operational for years, decades or
centuries.
 High speed is also a significant consideration. It
can operate much faster than their larger
counterparts.
