HOW NONOROBOT WORKS
POWERING THE NANOROBOT
Nanorobots might function at the atomic or molecular level to build
devices, machines, or circuits, a process known as molecular
Nanorobots might also produce copies of themselves to replace wornout units, a process called self-replication.
It has been suggested that a fleet of nanorobots might serve as antibodies
or antiviral agents in patients with compromised immune systems, or in
diseases that do not respond to more conventional measures. There are
numerous other potential medical applications.
A major advantage of nanorobots is thought to be their durability.

Breaking of kidney stone
Breaking of clots
Breaking up blood clots:
Nanorobots could travel to a clot
and break it up. This application
is one of the most dangerous uses
for nanorobots – the robot must be
able to remove the blockage
without losing small pieces in the
bloodstream, which could then
travel elsewhere in the body and
cause more problems. The robot
must also be small enough so that Nanorobots might carry small ultrasonic
signal generators to deliver frequencies
it doesn't block the flow of blood
directly to kidney stones.
•Breaking up kidney stones: Kidney stones can be intensely
painful -- the larger the stone the more difficult it is to pass.
Doctors break up large kidney stones using ultrasonic
frequencies, but it's not always effective. A nanorobot could
break up a kidney stones using a small laser.
•Parasite Removal: Nanorobots could wage micro-war on
bacteria and small parasitic organisms inside a patient. It
might take several nanorobots working together to destroy all
•Gout: Gout is a condition where the kidneys lose the ability
to remove waste from the breakdown of fats from the
bloodstream. This waste sometimes crystallizes at points
near joints like the knees and ankles. People who suffer from
gout experience intense pain at these joints. A nanorobot
could break up the crystalline structures at the joints,
providing relief from the symptoms, though it wouldn't be
able to reverse the condition permanently.
•Cleaning wounds: Nanorobots could help remove debris from
wounds, decreasing the likelihood of infection. They would be
particularly useful in cases of puncture wounds, where it might be
difficult to treat using more conventional methods.

There are three main considerations scientists need to focus on when looking at
nanorobots moving through the body -- navigation, power and how the nanorobot
will move through blood vessels.. These can be divided into one of two categories:
external systems and onboard systems.
External navigation systems : One of these methods is to use ultrasonic signals to
detect the nanorobot's location and direct it to the right destination. The signals
would either pass through the body, reflect back to the source of the signals, or
both. The nanorobot could emit pulses of ultrasonic signals, which could be
detected using special equipment with ultrasonic sensors.
Using a Magnetic Resonance Imaging (MRI) device , doctors could locate and
track a nanorobot by detecting its magnetic field.
Doctors might also track nanorobots by injecting a radioactive dye into the
Other methods of detecting the nanorobot include using X-rays, radio waves,
microwaves or heat
Onboard systems, or internal sensors, might also play a large role in navigation. A
nanorobot with chemical sensors could detect and follow the trail of specific
chemicals to reach the right location. A spectroscopic sensor would allow the
nanorobot to take samples of surrounding tissue, analyze them and follow a path
of the right combination of chemicals.
Powering the Nanorobot
Just like the navigation systems, nanotechnologists are considering
both external and internal power sources. Nanorobots could get power
directly from the bloodstream.
A nanorobot could use the patient's body heat to create power, but
there would need to be a gradient of temperatures to manage it. Power
generation would be a result of the Seebeck effect.
capacitor which has a slightly better power-to-weight ratio can also
Another possibility for nanorobot power is to use a nuclear power
External power sources include systems where the nanorobot is either
tethered to the outside world or is controlled without a physical tether.
Tethered systems would need a wire between the nanorobot and the
power source. The wire would need to be strong, but it would also need
to move effortlessly through the human body without causing damage.
A physical tether could supply power either by electricity or optically.

Nanorobots: Today and Tomorrow
Teams around the world are working on creating the first practical
medical nanorobot. robot ranging from a millimeter in diameter to a
relatively hefty two centimeters long already exist, though they are all still
in the testing phase of development and haven't been used on people.
We're probably several years away from seeing nanorobots enter the
medical market. Today's microrobots are just prototypes that lack the
ability to perform medical tasks.
In the future, nanorobots could revolutionize medicine. Doctors could
treat everything from heart disease to cancer using tiny robots the size of
bacteria, a scale much smaller than today's robots. Robots might work
alone or in teams to eradicate disease and treat other conditions.. Unlike
acute treatment, these robots would stay in the patient's body forever.
Another potential future application of nanorobot technology is to reengineer our bodies to become resistant to disease, increase our strength
or even improve our intelligence.
Will we one day have thousands of microscopic robots rushing around in
our veins, making corrections and healing our cuts, bruises and
illnesses? With nanotechnology, it seems like anything is possible
A nanostructured data storage device about the
size of a human live cell is implanted in the brain
could store a large amount of data and provides
extremely rapid access to this information.
But perhaps the most long-term benefit to human
society as a whole could be the drawing of a new era of
peace.We could hope that the people who are
independently well fed ,well housed,smart,well
educated,healthy & happy will have little motivation
to make war.Human being who have reasonable
prospect of living “normal” lifetime will learn patience
from experience,and will be extremely unlikely to risk
those “many lifetimes” for any but most of compelling
