Nanorobotics is the emerging technology field creating machines or robots whose components are at or close to the scale of a nanometre (10^-9 meters). More specifically, nanorobotics refers to the nanotechnology engineering discipline of designing and building nanorobots, with devices ranging in size from 0.1–10 micrometres and constructed of nanoscale or molecular components. The names nanobots, nanoids, nanites, nanomachines, or nanomites have also been used to describe these devices currently under research and development.
