Nanotechnology



Nanotechnology is molecular manufacturing or,
more simply, building things one atom or molecule
at a time with programmed nanoscopic robot
arms.
A nanometer is one billionth of a meter (3 - 4
atoms wide).
The trick is to manipulate atoms individually and
place them exactly where needed to produce the
desired structure.
Introduction to robotics

Like nanotechnology, Robotics is the use
of technology to design and
manufacture (intelligent) machines, built for
specific purposes, programmed to perform
specific tasks.
What is a Robot?


Robots are programmable
machines
They range from small,
miniature machines, to
large crane size
constructions
Introduction to Nanorobotics



It deals with the controlled manipulation of
objects with nanometer scale dimensions
Nanomanipulation is most effective
process.
It is concerned with construction and
programming of robots with overall
dimensions at the nanoscale.
Nanorobotics


It is concerned with atomic and
molecular-sized objects and is
also called Molecular Robotics.
Nanorobotics research has
proceeded along two lines:
- first is devoted to simulation
with nanoscale dimensions.
- second involves manipulation
with macroscopic instruments.
Nanorobot




A nanorobot is a specialized
nanomachine.
It has dimensions on the order of
nanometers.
Typically 0.5 to 3 microns large with
1-100 nm parts.
The possibility of nanorobots was
first proposed by Richard Feyman in
his talk “There’s Plenty of Room at
the Bottom” in 1959.
Features of Nanorobots




Nanorobots can be categorized into two groups
called autonomous robots and insect robots.
A major asset of nanorobots is that they require
very little energy to operate.
Durability is another potential asset, may remain
operational for years, decades or centuries.
High speed is also a significant consideration. It
can operate much faster than their larger
counterparts.
Nanorobots in medicine




It’s structure will have two spaces consisting of
interior and exterior.
They will communicate with doctor by encoding
messages to acoustic signals.
The production of nanorobots has taken a step
closer to real application due to technological
advancements such as AFM , bionic motors,
nanotanks, DNA as computer, and nano robotics
arms.
Leonard Adleman confirmed that DNA is
programmable in computers.
Applications using Nanorobots





To cure skin disease and as cosmetic cream.
Can be used a a mouthwash to do all brushing
and flossing.
Would augment immune system by finding and
killing bacteria and viruses.
It would prevent heart attack , kill cancer cells
etc.
To monitor potentially dangerous
microorganisms in the ocean.
Nanorobots can be used in blood cell
to detect pathogens.
Fractal Robots


Fractal robot is a new kind of robot
made from motorized cubic bricks
that move under computer control.
These cubic motorized bricks can
be programmed to move and
shuffle themselves to change
shape to make objects likes a
house potentially in a few seconds
because of their motorized internal
mechanisms.
Fractal Robot Example

Example of a Dog shaped
fractal robot changing into a
couch
Fractal Robots and Nanotechnology



Nanotechnology materials are very costly.
On the other hand, molecular nanotechnology
consumes hundreds of millions of dollars in research
funding and does not produce a profit at this moment in
time because it is a very difficult subject to research and
develop.
Fractal robots are a half way house between the difficult
extremes of molecular nanotechnology and practical
ease of electromechanical engineering. They can
implement Digital Matter Control products and prepare
us for the coming future.
Fractal Robots & Nanotechnology
Compatible Computers


The design of a fractal nanocomputer is not an
easy task using conventional principles.
However, using fractal nanotechnology principles,
the exercise reduces to a fairly simple exercise
where you build a fractal nanocomputer at the
large scale and providing you followed fractal
principles, the computer technology scales
downward to whatever resolution limit imposed by
the technology you are using.
Employing the functionality of the Built-in
Microcontroller of a Robotic Cube



All active robotic cubes have a limited
microcontroller to perform basic operations such
as communications and control of internal
mechanisms.
To make a fractal nanocomputer, you can
increase the power of the microcontroller and / or
farm out existing functionality to turn the system
into a fractal nanotechnology compatible
computer.
Small robotic cubes can be added to the same
structure increasing the power.
Employing the power of the fractal
operating system






The fractal operating system plays a crucial role in
making the integration of the system seamless and
feasible even if there are billions of CPUs in the
collective.
A fractal operating system uses a number of features to
achieve these goals.
1. Seamless integration of software, data and hardware
2. Transparent data communications
3. Data compression at all levels including
communications
4. Awareness of built in self repair
SELF-REPAIR IN FRACTAL
ROBOTS.


Self repair is an important
breakthrough for realizing micro
and nanotechnology related end
goals.
Three different kinds of self repair
-Cube replacement
-Usage of plates to construct the
cubes.
-Using smaller fractal machines to
affect self repair inside large cubes.

Applications of fractal robots





It can be used in medicine.
In mining.
Using fractal robots it is possible to build
even a space station.
Can be used to build roads and clear
mines
In agriculture
Conclusions



All of the current developments in technology
directs human a step closer to nanorobots
production.
Nanorobots can theoretically destroy all common
diseases of the 20th century, thereby ending much
of the pain and suffering.
Although research into nanorobots is in its
preliminary stages, the promise of such
technology is endless.
