NANO -ROBOTICS

3

Definition of Nanotechnology :-

Nanotechnology(sometimes referred as ‘nanotech ’) is the study of manipulating matters on an atomic and molecular scale.

Generally nanotechnology deals with developing materials, devices or structure whose at least one dimension is sized from 1 to 100 nanometers.

4

Definition of Nano-robotics

Nano-robotics is the technology of creating machines or robots at or close to nano(10-9) dimension.

The names nanobots, nanoids, nanites, nanomachines and nanomites have also been used to describe these devices largely in research-and-development phase.

5

Few words about Nano-robotics Research in Nano-robotics began in the late 1980’s.Aroundthis time, K. Eric Drexler published his research onNano systems.

From there research developed along with two paths:- 1. Design and simulation of robot with nano scale dimensions. 2. Manipulation or assembly of nano scale components with microscopic instruments.

Nano robot are nano machine embedded in our bodyperforming their duties as disciplined soldiers.

6

According to current theories, nano-robots will possess at least two-way communication.

A network of special stationary nano-robots might bestrategically positioned throughout the body, logging eachactive nano-robot as it passes, then reporting those results,allowing an interface to keep track of all of the devices in thebody.

Simulation is an essential tool for exploring alternatives in theorganization, configuration, motion planning, and control ofnano-devices exploring the human body.

Basically, we may observe two distinct kind of nano-robotutilization. One is nano-robots for the surgery intervention,and the other is nano-robot to monitor patients’ body.

STRUCTURE OF NANO-ROBOTSNano-robots consists of :-1. Molecular Sorting

Rotor.2. Propellers.3. Fins.4. Sensors.

Molecular Sorting Rotors:-

Made up of Carbon nano-tubes.

SWNT’s can be used to generate a mechanical motion.

Nano-tubes with nano-gears are responsible for changing direction of movement. It is used for molecular manipulation.

Structure of nano-robots

8

Propellers:- It is used to drive forward and backward. They are bi-directional propellers.

Fins:- These are fitted along

with the propellers used to propel the device. The three fins uses plane surface for navigation.Sensors:-

These are thenavigational acoustic sensors.

9

WIFI-CMOS with wireless communication is feasible way to interface with nano-robots i.e. tracking, operation, diagnosis.

CMOS:- It enable production of high performance nano- devices.

APPLICATIONS OF NANO ROBOTICS

This is caused by fatty deposits on the walls of arteries. The device should be able to remove these deposits from the arterywalls.

ARTERIOSCLEROSIS:-

TUMORS TREATMENT:-Drillers, Peppers and Stringers engage in a delicate surgical operation to remove a cancer tumor.

11

Nano-robots may carry small ultra-sonic signal generator to deliver frequencies directly to the kidney stone which in-turn get crushed and pass out through urine.

KIDNEY STONE:-

Nano-robots can be used in the body to break up blood clots into smaller pieces before they have a chance to break free and move on their own.

Nano-robots are used in space-ships, space-suits and equipments used to explore planets and moon

12

FUTURE OF NANO-ROBOTS

In nano-computers using nano-tubes and nano-wires.

In the detection of blood sugar level in human blood.

In the detection and treatment of cancer cells.In Brain -Augmentation-to replace dead cells with new cells

13

Speed up of Medical Treatment.

Faster and More Precise Diagnosis.

Verification of Progress and Treatment.

Nano-structuring is expected to bring about lighter, stronger and programmable materials.

Non-degradation of Treatment Agents.

ADVANTAGES OF NANOMEDICINE

14

Nano particles will penetrate living cells and accumulate in animal organs and can perhaps enter the food chain.

There is no regulatory body dedicated to check this potent and powerful invasion.

Their impact on environment is unknown e.g. Nano-tubes of carbon use gallium & arsenic and minute traces of gallium arsenide which could prove toxic in the human body.

Changes in the proteins due to the presence of nano- particles in the blood stream could trigger dangerous effects like blood clotting.

LIMITATIONS OF NANO-ROBOTICS

15

From these types of inventions, it will be useful for man tocure many diseases and lead a fantastic life.

The same technique is used in various treatments like cancer, breaking kidney stones, brain surgery, heart surgery.

Nano-robots could improve the performance of spaceships,spacesuits and equipment used to explore planets andmoons.

The major advantage of nano-robots is thought to be their durability, in theory, they can remain operational for years, decades or centuries.

Nano-robot might function at the atomic and molecular level to build devices, machines known as molecular manufacturing.
