  13. What is nanorobotics?

  14. Nanorobotics is emerging tehnology field of creating machines or robots  whose components size is on scale of a nanometar 10- 9 meters • More specifically, nanorobotics refers to the nanotehnology which is engineering discipline of designing and building nanorobots • nanobots, nanoids, nanites, nanomachines or nanomites are also used to describe the nanorobots

  15. Use of nanorobots • Nanorobots are still in developmentphase but some primitive nanomachines havebeentested • For example there is is a sensorhavingaswitchapproximately 1.5 nanometersacross, capable of countingspecificmolecules in a chemical sample • The first important use of nanorobots mightbe in medicine where the nanorobots willbe used for identifying and destroyingcancercells which will save manylives • Nanorobots willprobably also be used for “repairing” human bodieswhere the nanorobots willcarryourbodycells to the rightplaces in ourbody

  16. Bottom-up Arranged one way, atoms make up soil, air and water. Arranged another way they make up strawberries or smoke. Ultimate Nanotechnology would be to build at the level of one atom at a time and to be able to do so with perfection.

  17. Nature’s Toy box. ATOMIC LEGO Molecular assembly is like a Lego set of 90 atoms that we can use to build anything from the bottom up! You just use every atom that you want. All of the elements in the periodic table can be mixed and matched,

  18. Problems • As already we know nanorobot is very expensive to build because of thercomplexity and verysmallsize it wouldprobably be necessary for very large numbers of them to work together to perform microscopic and macroscopic tasks... • So if weneed a lot of them to do something and to buildjust one is veryexpenisve the problem is how to replicatethem. • Scientistsdidn’t came up with idea how to do that...yet. ...what if theybuild nanorobots who canuncontrolledreplicatethembythemselfs in natural environment? Then one of the most bizzarescenariouswouldhappen the GRAY GOO.

  19. Graygoo • Greygoois a hypotheticalend-of-the-world involvingmolecularnanotehnology which out-of-controlself-replicatingrobotsconsume all matteron Earthwhilebuilding more of themselves • Self-replicatingmachines of the macroscopicvarietywereoriginallydescribedbymathematicianJohnvon Neumann and are sometimesreferred to as vonNumannsmachines • he termgreygoo was coinedbynanotechnologypioneerEricDexler in his 1986 book”Engines of Creation”statingthat "wecannotaffordcertaintypes of accidents."

  20. Dexlersaid: imaginesuch a replicatorfloating in a bottle of chemicals, makingcopiesofitself…the first replicatorassembles a copy in one thousandseconds, the tworeplicatorsthenbuildtwo more in the nextthousandseconds, thefourbuildanotherfour, and the eightbuildanothereight. At the end of ten hours, there are not thirty-six new replicators, but over 68 billion. In lessthan a day, theywouldweigha ton; in lessthantwodays, theywouldoutweigh the Earth; in anotherfourhours, theywouldexceed the mass of the Sun and all the planetscombined — if the bottle of chemicalshadn't rundrylongbefore.

  21. Advantages and disadvantages of inorganic nanobots Advantages: • well-understood component behaviour • ease of programming • ease of external control • unlimited chemistry (with enough energy) Disadvantages: • difficult and expensive to make • not self-reproducing • difficulty of communicating with organic systems • must carry own (limited) payload

  22. Advantages and disadvantages of organic nanobots Advantages: • easy to make using genetic engineering • self-reproducing (cheap) • easily communicate with other organic systems • protein factories manufacture payload Disadvantages: • poorly understood component behaviour (proteins) • hard to program • limited external control mechanisms • limited to CHON chemistry and needs water

  23. Size Matters • It’s not just how big you are • It’s what you can do with it
