UTILITY FOG

1. UTILITY FOG PRESENTED BY : seminartopics.info

2. INTRODUCTION • Invented by Dr.J.Stross Hall. • Foglets consists of microscopic computers ,gears,motors with telescopic arms . • Arms interlock –power & communication. • Individual foglets 2-3 % of space. • TRANSPARENT UPCLOSE & CLOUDY AT A DISTANCE. • Trillions of foglets- mass ,motion, appearance & strength.

3. STRUCTURE OF FOG

4. STRUCTURE OF FOGLET

5. DAILY APPLICATIONS • Paint the wall with U Fog. • Make walls of U Fog . • Can form any object. • Obselete objects can form floor. • Any hardness ,temp. • Same precision as measured by human senses.

6. The Stuff That Dreams Are Made Of : • Little robot called Foglet.-12 arms. • Grippers at the end of arms. • Present as well as absent-large structures. • Foglets can simulate any environment-a park & at next moment a forest. • In a room filled with Foglets –walk without noticing anything.

7. MODES OF OPERATION • Native & fog. • Native –individual foglets move. • Fog - move enmass • Why we fill air with microscopic robots ? • Completely imaginary construction • Anything imaginable can be given tangible reality • Bacteria sized pieces and stored • Bridges physical reality and virtuality

8. Structure of Utility Fog • Nanotech designs based on carbons • Forms a crystal which is very stiff and strong • Structural element of Foglet made of aluminium oxide • Inside this sensitive non mechanical components can operate • Each Foglet has 12 arms • Arms rotate on the joint at the base • Gripper rotate about arm axis

9. Structure contd… • Only load carrying motor is extension or retractor motor • Swivel and rotate axis do not drive any kind of load • Gripper-Hexagonal structure with 3 fingers on alt.faces of hexagon • Forces transmitted axially through grip • Space bounded by arms form alternate tetrahedrons and octahedrons • Both these are rigid shapes

10. Movement of Fog • Fog consists of layers of Foglets • Each Foglet uses six arms for interlocking with Foglets of same layer • Thus 2-D rigid fabric of equi. Triangles formed • The Foglets slides to change shape • Fog moves an object by setting up a seed shaped zone around it • Extension and retraction rate of arm-10m/s • Avg. interlayer movement rate-100m/sec/mm of thickness of layer

11. Properties of U Fog. • U Fog - density- 0.2 ; tensile strength -100 psi • Material properties are isotropic • Without altering lattice connectivity Fog can contract to 1/3rd and reduce volume to 1/5th • An appropriate mass or UFog can simulate most physical properties

12. THE GRIP

13. Foglets in detail • Foglets run on electricity • They store hydrogen as energy source • Foglets slide or move objects • When 2 layers move past each other arms move 100 thousand times • If this motion dissipative consumes lot of power • Arms being pushed receive same amt. of energy

14. Foglets – Internal Schematic

15. Communications & Control • 12 arms & 3 axis control • Simpler controllers give commands • Each computer - nano watts • Trillions of computers –few kW heat produced • Foglet when stationery- “ stand – by mode “ • this reduces 90 % heat generation

16. SYNERGISTIC COMBINATION WITH OTHER TECHNOLOGIES • Fog robot – fog cannot do anything requiring “high strength &power “ • Tapping other sourcesof energy • Solar energy • Communicate with some person/terninal • Within some specified area

17. PROPERTIES & USES • Extension of human being and his senses • No permanent buildings ,roads,cars • Park,forest, ancient civilization • Efficiency increases- no wear & tear • Storing information easier • All physical possesion inside your pocket • Monster computers • Processor of foglet more powerful than supercomputer • 26 million foglets /cu.inch

18. LIMITATIONS OF U FOG • “outside the everyday exp.” • Things that fog isn’t capable of doing: • Hard metal-drill bit • High strength & low weight • High heat • Anything req chemical transformation • Food • Can simulate wind but not air • Unemployment

19. DESIRABLE LIMITATIONS • A person capable of “projecting objects” & “forces” anywhere in any form • “Who gets to control what” –a very contentious question • Physical proximity • Personal space • This single protocol can prevent crimes and violence • Physically perpetrated theft impossible

20. Advantages of U Fog Environment. • Car crash • Fog house –protection within 98%of lethal blast area • Bacteria free • Accidents in factories can be avoided • Household accidents avoided- staircas, knife , bookshelf. • Cleaning –non –existant • Factories- transportation & operation of machines

21. SPACE EXPLORATION • The major sys Of space ships • Fill cabin with utility fog -- never worry about out of reach of hand hold • Any equipment can be simulated • Non simulable can be embedded • Fog inside space suit • Surround space station with u fog-radiation shielding • Tourists –take along batch of heavy duty u-fog

22. CONCLUSION • Using the mass computing power contained in these trillions of foglets they could be programmed with a wide spectrum of behaviours that mimic materials of different mass,motion appearance and function which will enhance the capabilities of human race in the coming generations . • The illutions which we see in films and we have dreamed of can be implemented using the capabilities of utility fogfor which research is going on in a high pace.
