Nanorobotics is the technology of creating machines or robots at or close to the scale of a nanometre. Nanorobotics refers to nanotechnology engineering discipline of designing and building nanorobots. Nanorobots (nanobots or nanoids) are typically devices ranging in size from 0.1-10 micrometres and constructed of nanoscale or molecular components. Another definition is, a robot refers to precision interactions with nanoscale objects, or manipulatin with nanoscale resolution. Hence even an atomic force microscope when configured to perform nanomanipulation. and macroscale robots or microrobots which can move with nanoscale precision can also be considered nanorobots.
