Nanorobots are tiny machines used to cure diseases inhuman or in any organism.

Performs task at nanoscale dimensions.

The size of nanorobots is 10 -9.

The prefix ‘ nano ’ means billionth.

WHAT ARE NANOROBOTS?

Introduction



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 cellsuntouched.

The patients has no awareness of devices working insidethem.

STRUCTURE OF NANOROBOTS

Molecular sorting rotors.

Propeller.Fins.Sensors.

Consists of,

Molecular sorting rotors:Made up of carbon nanotubes.

Sheet of carbon atom forms a

carbon nanotubes.

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.

POWERING THE NANOROBOT• Nanotechnologists are considering both external and internal power sources.

• Nanorobot could get power directly from the bloodstream .

• A nanorobot could use the patient's body heat to create power.

• The Seebeck effect occurs when two conductors made of different metals are

joined at two points that are kept at two different temperature.

• External power sources include systems where the nanorobot is either tetheredto the outside world or is controlled without a physical tether.

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.

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.

• 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.

To know the location of nanorobotswhere it goes we useultrasonic technique .

Nanorobots must be able to produceultrasonic waves by passing a signal topiezoelectric membrane.

Several signal processing techniquesare used to track this ultrasonic signaland to find the location at any time.

POSITIONING

stream .

DETECTION

Sensors are used to locate the dead cancer cells.

To control the nanorobots as per our wish fit the TV camera .

Sensors are used to receive the signals and do the operationsaccording to signals send by remote control unit.

DESTRUCTION

The cancer cells are removed by passing INFRA- RED RAYS on the nanorobots.

The INFRA- RED RAYS can be generated externally.

Fig: View of nanorobot removing the cancer cells.

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

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-outunits, a process called self-replication .

The major advantage of nanorobots is thought to be their durability, intheory, they can remain operational for years, decades or centuries.

18



APPLICATIONS

Treating arteriosclerosis

Breaking up blood clots

Fighting cancer

Parasite Removal

Breaking up kidney stones

19



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.
