Introduction
WHAT ARE NANOROBOTS?

• Nanorobots are tiny machines used to cure
  diseases in human or in any organism.
• Performs task at nanoscale dimensions.
• The size of nanorobots is 10 -9.
• The prefix nano means billionth.

4
USE OF NANOROBOTS IN HUMAN BODY

• A doctor offers the patient an injection of a
  nanorobot.
• Seeks out cancer cells and destroy them.
• Dispells the disease at the source, leaving the
  healthy cells
• untouched.
• The patients has no awareness of devices working
  inside
• them.

NANOROBOTS IN HEART SURGERY

• Blood vessels play an important role in
  supplying blood
• to all parts of our body.
• Due to the fatty deposition on the walls of
  blood vessels
• blood will not move freely to all parts.
• These leads to heart attacks and damage the
  vital
• organs.

6
STRUCTURE OF NANOROBOTS
Consists of,

• Molecular sorting rotors
• Propeller
• Fins
• Sensors

Continued

• Molecular sorting rotors
• Made up of carbon nanotubes.
• Sheet of carbon atom forms a
• carbon nanotubes.
• 
  
• SWNTs can be used to generate mechanical
  motion.
• Nanotube with nanogears used for changing the
  direction of movement.

• Propeller
• Like that in nanorobots it is used to drive
  forward against
• the blood stream.
• Fins
• Fitted along with the propellers used to propel
  the device.
• Sensors
• Fitted externally and internally with the
  nanorobots to receive the
• signal for correct guidance.

INJECTION OF NANOROBOTS

• Find a way to introduce nanorobots into the body
  for surgery.
• Allow it to do the operation without ancillary
  damage.
• So the nanorobots are made smaller than the
  blood vessels as it
• can travel.
• Femoral artery in the leg is considered to be a
  largest artery in our body.
• So the nanorobot is injected in this artery.

10
NAVIGATION

• Every living thing needs area to move.
  
• Nanorobots use blood flow for its movement.
• In order to move the nanorobots in blood flow,
• To satisfy this, nanorobots should be made with
  electric motors to turn propeller.

vessels. (http//www.scribd.com/search?catredesig

• Speed of blood
• Get through the heart without stuck
• React with changes in blood flow rate
• Able to change the direction according to the
  blood stream

11
POSITIONING

• To know the location of nanorobots
• where it goes we use
• ultrasonic technique.
• Nanorobots must be able to produce
• ultrasonic waves by passing a signal to
• piezoelectric membrane.
• Several signal processing techniques
• are used to track this ultrasonic signal
• and to find the location at any time.

nanorobot with the blood stream ref(5).

DETECTION
Fig Nanorobots towards a destination ref(6).

• Sensors are used to locate the fatty deposits.
• To control the nanorobots as per our wish fit
  the TV camera .
• Sensors are used to receive the signals and do
  the operations
• according to signals send by remote control
  unit.

13
DESTRUCTION

• The fatty deposits (or) clots are removed using
  special blades fitted with nanorobots.
• Continuous (or) pulse signal is used to activate
  the blades.

Fig View of nanorobot removing the fatty deposit
ref(4).

• To take nanorobots from the body we use two
  methods one is retrace our path
• upstream another is making small surgery to
  remove.

14
APPLICATIONS

• Treating arteriosclerosis
• Breaking up blood clots
• Fighting cancer
• Parasite Removal
• Breaking up kidney stones

15
ADVANTAGES OF NANOROBOTS

• Rapid elimination of disease.
• Nanorobot might function at the atomic and
  molecular level to build devices,
• machines or circuits known as molecular
  manufacturing.
• Nanorobots might also produce copies of
  themselves to replace worn-out
• units, a process called self-replication.
• The major advantage of nanorobots is thought to
  be their durability, in
• theory, they can remain operational for
  years, decades or centuries.
•  

16
CONCLUSION

• The nanorobots are used in heart surgery, due
  to this number of risks and side effects behind
  is reduced.
• The same technique is used in various treatments
  like cancer, breaking kidney stones, breaking
  liver stones, parasite removal only with slight
  modification.
• Within ten year several advancement technologies
  should be made from this nanorobotics.
