4/20

anorobots are quintessential

noelectromechanical systems designed to

rform a specific task with precision at nanoscaleensions.

nanorobots is the

chnology of creatingbots at or close to

croscopic scale of a

nometer (10-9 m)

nanometer is just one

lionth of a meter,a

ngth in which only 10

oms can be placed.

D FOR NANOBOTS

Nanomachines are largely in the research-and-developmentphase, but some primitive molecular machines have been

tested.

An example is a sensor having a switch approximately 1.5

nanometers across, capable of counting specific molecules in a

chemical sample.

The first useful applications of nanomachines, if such are

ever built, might be in medical technology, where they might beused to identify cancer cells and destroy them.

Another potential application is the detection of toxic

chemicals, and the measurement of their concentrations, in theenvironment

The variousmponents in the

anorobot design

ay include onboard

nsors, motors,

anipulators, power

pplies, and

olecular computers.

Nanorobots will possess full panoply of

utonomous subsystems whose design iserived from biological models

The manipulator arm can be driven by a

detailed sequence of control signals.

Control signals received by the robot arm via an

onboard sensor using a simple "broadcast

architecture"[43, 44, and 45]

There are two main approaches to building at the

nanometer scale1.positional assembly

2.self-assembly.

NAVIGATIONanorobot navigation:

- Uses plane surfaces (three fins total)

- Propulsion by bi-directional propellers:

two simultaneously counter-

ating screw drives - navigational acoustic sensors

nanorobots can move with

-degrees-of-freedom, i.e.,

bitrary translation and

tation fins and propellers.

External navigation systems

ight useS ULTRASONIC

GNALS to pilot the

norobot to the rightcation

NANO IN HIV CONVERSIONNanorobots Consists of three main parts like

1. DNA sensor,2. CPU,

3. RNA converter & the power system.

REQUIREMENTS

It should be very small so that the bloodcapillary flow is not affected.

It should not be affected by the WBC.

It should convert the infected WBC into theoriginal WBC in a very faster manner.

It should be made of cheaper rates, so thatthe patient can afford it easily.

ADAVANTAGES

The nanorobots do not generate any harmfulactivities there is no side effect.

It operates at specific site only.

The initial cost of development is only high

but the manufacturing by batch processingreduces the cost.

16/20

The nanorobot should be very accurate,otherwise harmful effects may occur.

The initial design cost is very high.

The design of this nanorobot is a very

complicated one

17/20

LIMITATIONS

Chemists object that an assembler could

need ten robotic fingers to carry out their

operations and that there isnt room for them

all.

This technology is still science fiction and

an unfamiliar territory.


18/20

CONCLUSION

The old dreams of expanding the

biosphere beyond our one vulnerableplanet suddenly look feasible once

more.

NOTHING IS PERMANENT EXCEPT

CHANGE
