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 in at
least one dimension, and involves
developing materials or devices within
that size.

5. 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
6. What is Nanorobotics?
• Programmable assembly of nm-scale
components either by manipulation with macro
or micro devices, or by directed self-assembly.
• Design and fabrication of robots with overall
dimensions at or below the mm range and
made of nm-scale components.
• Programming and coordination of large
numbers (swarms) of such nanorobots.
7. • Known as nanorobot pioneer,
adriano Cavalcanti is the medical
nanorobotics inventor for the
pratical hardware architecture of
nanorobots, which was integrated
as a model based on
nanobioelectronics for applications
in environmental monitoring,
brain aneurysm, diabetes, cancer
and cardiology. His advanced
prototype provided a suitable
integrated circuit approach, using
an effective wireless platform
8. NANOBOT ISSUES
• Sensors
• Computers and Control
• Actuators and Propulsion
• Power
• Communications
• Interfaces and Integration
– nano/micro/macro
– organic/inorganic
– biotic/abiotic
• Programming and Coordination
Nanorobots raise all the issues that are
important for NEMS
9. CONSTRUCTION AND DESIGN
• Designs derived from biological models
• Components: onboard sensors, motors, manipulators ,
power suppliers,molecular components
• Best known biological sample is ribosome used to
constuct robotic arm
• Manipulator arm driven by detailed sequenc e of
controlsignals
• Control signals received by robotic arm via on board
sensors using broadcast architecture
• Assemblers are molecular machine system perform
molecular manufacturing on atomic scale

13. APPLICATIONS IN MEDICAL FIELD
• Breaking up blood clots
• Fighting cancer
• Parasite removal
• Gout
• Breaking up of kidney stones
• Arterioscleriosis

15. Nanorobots might carry small ultrasonic signal
generators to deliver frequencies directly to kidney
stones
16.
17. Nanorobots may treat conditions like
arteriosclerosis by physically chipping away the
plaque along artery walls

21. NANO SENSORS
• Provides realtime
information about
antibodies to antigens,
cell receptors to their
glands etc..
• Used for drug detection
• To detect chemical
vapours at low
concentation based on
surface stress.
22. IN SPACE TECHNOLOGY
• Nanorobots can be used to actively
repair damaged suit materials while an
astronaut is in the field
• specialized Marssuit Repair Nanorobots
(MRN). MRN nanorobots operate as
space-fillingpolyhedra to repair damage
to a Marssuit
• Measurement of toxic elements in
environment

24. NANOBOTS CAN MINE
GARBAGE DUMPS
• Nanobots are going to
make it easier and cheaper
to pull out, clean up and
create useful commodities
for us to reuse. And once
you understand the vast
potential for
Nanotechnology, you are
going to understand that
our future is going to be so
bright... it is going to be so
……….freakin' brilliant!
25. • With 15,342 atoms,
this parallel-shaft
speed reducer gear
is one of the largest
nanomechanical
devices ever
modeled in atomic
detail
26. ADVANTAGES
• The microscopic size of nanomachines
translates into high operational speed
• individual units require only a tiny amount of
energy to operate
• Durability is another potential asset
• nanites might last for centuries before
breaking down
27. DISADVANTAGES
• risk of cancer
• may affect human health by introducing
toxicity in blood
• Replication may become out of control
