  3. 3. NANO TECHNOLOGY • Nanotechnology (sometimes shortened to "nanotech") is the study of manipulating matter on an atomic and molecular scale. • Generally, nanotechnology deals with structures sized between 1 to 100 nanometer and involves developing materials or devices within that size.
  4. 4. ROBOTICS • Robotics is the branch of technology that deals with the design, construction, operation, structural disposition, manufacture and application of robots. Robotics is related to the sciences of enginnering, electronics, mechanics and software.
  5. 5. NANOROBOTICS:  Nanorobotics is the technology of creating machines or robots at or close to the microscopic scale of a nanometer (10-9 ).  Nanorobots would typically be devices ranging in size from 0.1-10 micrometers.  The main element used will be carbon in the form of diamond nanocomposites because of the strength and chemical inertness of these forms.
  6. 6. What is Nanobot?  A nanobot is a nanotechnological robot machine, also called a nanite, which is a mechanical or eletromechanical device whose dimensions are measured in nanometres. A design of nanorobot with sensors, molecular sorting rotors and fins
  7. 7. Properties & componentsProPerties & comPonents of medical nanobots
  8. 8. MEDICAL NANOROBOTIC APPLICATIONS • Breaking up blood clots • Cancer therapy • Parasite removal • Targeted drug delivery • Breaking up of kidney stones • In treatment of Arterioscleriosis • Neuron replacement
  9. 9. Nanorobots might carry small ultrasonic signal generators to deliver frequencies directly to kidney stones
  10. 10. Nanobots in Cancer therapy
  11. 11. Nanorobots may treat conditions like arteriosclerosis by physically chipping away the plaque along artery walls
  12. 12. Nanobot in action A nanorobot machine roaming through the bloodstream, injecting or taking samples for identification and determining the concentrations of different compounds.
  13. 13. Nanorobots can be used in blood cell to detect pathogens.
  14. 14. IN SPACE TECHNOLOGY • Nanorobots can be used to actively repair damaged suit materials while an astronaut is in the field • Measurement of toxic elements in environment
  15. 15. ADVANTAGES • Speed up of medical treatment • Faster and more precise diagnosis • Minimum side effects • In medical field we will have microscopic robots floating in our blood streams fighting against cancerous cells • Speed up of medical treatment. • Faster and more precise diagnosis. • Minimum side effects. • These are used to cure many diseases which are not possible from ancient methods. advantages
  16. 16. DISADVANTAGES • The initial design cost is very high. • The design of the nanorobot is a very complicated one. • Hard to program. • Limited external control mechanisms.
  17. 17. conclusion  All of the current developments in technology directs human a step closer to nanorobots production.  Nanorobots can theoretically destroy all common diseases of the 20th century, thereby ending much of the pain and suffering.  Although research into nanorobots is in its preliminary stages, the promise of such technology is endless.  Nanobots are going to revolutionize the medical industry in future.  Technology may rule us !
