0 an extremely small robot (= a machine controlled by a computer that can do things automatically)
The end result would not be a true nanobot it is concluded, but something much bigger.
It is evident that to create a self-replicating nanobot would take, we are told, billions of atoms.
These nanobots mutated the bodies of those they came into contact with, giving them super powers and enhanced abilities.
Jester did this due to nanobots in his system which would electrocute him if he didn't do as he was told.
He is shown a very complicated machine used to make the nanobots from bacteria.
These nanobots, although evolved alongside the other swarms, do not show aggressive predatory behavior.
The nanobots obey, and begin stripping him down.
As a result, hazardous elements such as the assemblers, the bacteria, and the nanobots were blown into the desert, evolving and eventually forming autonomous swarms.
