NANOROBOTICS
[attachment=67578]
ABSTRACT
Nanorobotics is the technology of creating machines or robots at or close to the
microscopic scale of a nanometer(10−9meters). More specifically, nanorobotics refers to the
still largely hypothetical nanotechnology engineering discipline of designing and building
nanorobots, devices ranging in size from 0.1-10 micrometers and constructed of nanoscale or
molecular components.
The advanced nanorobotics technology needed to manipulate materials at this scale, a
million times smaller than a grain of sand, is being developed .Due to modern technologies it
is possible to create some nanorobots. This nanorobots are mainly used in medical treatments
of cancer and other diseases. Image processing/vision control and sophisticated sensors, will
be the key to releasing such nano-manipulation.
This seminar presents the major aspects, study, applications of nano robotics
which are at the verge of implementation and would be no less than revolution in the field of
medicine if brought into reality. This seminar also presents how nanorobots works, their
importance and Advantages and disadvantages of nanorobotics.
NANOROBOT INSPIRATION
Assuming the nanorobot isn't tethered or designed to float passively through the
bloodstream, it will need a means of propulsion to get around the body. Because it may
have to travel against the flow of blood, the propulsion system has to be relatively strong
for its size. Another important consideration is the safety of the patient -- the system must
be able to move the nanorobot around without causing damage to the host.
WORKING OF NANOROBOTS
Imagine going to the doctor to get treatment for a persistent fever. Instead of
giving you a pill or a shot, the doctor refers you to a special medical team which implants
a tiny robot into your bloodstream. The robot detects the cause of your fever, travels to
the appropriate system and provides a dose of medication directly to the infected area.
POWERING THE NANOROBOT
Just like the navigation systems, nanotechnologists are considering both external
and internal power sources. Some designs rely on the nanorobot using the patient's own
body as a way of generating power. Other designs include a small power source on board
the robot itself. Finally, some designs use forces outside the patient's body to power the
robot.
Nanorobots could get power directly from the bloodstream. A nanorobot with
mounted electrodes could form a battery using the electrolytes found in blood. Another
option is to create chemical reactions with blood to burn it for energy. The nanorobot
would hold a small supply of chemicals that would become a fuel source when combined
with blood.
FIGHTING CANCER
Doctors hope to use nanorobots to treat cancer patients. The robots could either
attack tumors directly using lasers, microwaves or ultrasonic signals or they could be part
of a chemotherapy treatment, delivering medication directly to the cancer site. Doctors
believe that by delivering small but precise doses of medication to the patient, side effects
will be minimized without a loss in the medication's effectiveness.
ADVANTAGES:-
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.
In medical field we will have microscopic robots floating in our blood streams
fighting against cancer cells, AIDS HIV virus and genetic disorders or even
ageing.
Nanorobots will treat and find disease, and restore lost tissue at the cellular level.
Nanorobots will be able to monitor neuro-electric signals and stimulate bodily
systems.
1.7.2 DISADVANTAGES
The initial design cost is very high.
The design of the nanorobot is a very complicated one.
Maintenance is difficult
Hard to Interface, Customize and Design, Complex.
CONCLUSION
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. Some believe that semiautonomous nanorobots are
right around the corner -- doctors would implant robots able to patrol a human's body,
reacting to any problems that pop up. Unlike acute treatment, these robots would stay in
the patient's body forever.
Another potential future application of nanorobot technology is to re-engineer our
bodies to become resistant to disease, increase our strength or even improve our
intelligence. Dr. Richard Thompson, a former professor of ethics, has written about the
ethical implications of nanotechnology. He says the most important tool is
communication, and that it's pivotal for communities, medical organizations and the
government to talk about nanotechnology now, while the industry is still in its infancy.
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. Kudos to the engineers for this
revolution. Ultimately one can what a piece of work MAN is
