Utility fog is active metamorphic multiagent system consisting of a conglomeration of nanorobots. It is basically a 'Fractal Robot'(A geometric pattern that is repeated at every scale and so cannot be represented by classical geometry), made up of trillions of smaller bots, like the polymorphic liquid metal robot in the movie Terminator 2. The basic building block of Ufog is called a foglet. It consists of a swarm of nanobots ("Foglets") that can take the shape of virtually anything, and change shape on the fly. Dr. J. Storrs Hall of The Institute for Molecular Manufacturing, Palo Alto, CA, is considered as the originator of the Utility Fog concept.
