What is a robot?
A robot is a mechanical or
virtual artificial agent,
usually an electro-
mechanical machine that is
guided by a computer
program or electronic
be autonomous or semi-
What is a Nanobot?
Nano-Robots are the robots that are simply
known as the controllable machines at the
nano meter or the molecular scale,
composed of nano-components.
What do you mean by
the term ‘nano-scale’?
The word ‘Nano’ means a scale of
10−9 metre; having or involving dimensions
of less than 2000 nanometres.
Most common examples of nano-scale
substances are Fullerene, our DNA,
Carbon Nano Tubes..etc
For a size comparison, the width of the
human hair is said to be greater than
Types of nanobots
Biochip Nubots Bacteria
Biochip based nanorobot
Usually built by the joint use
components such as single
electron transistors, carbon
nano tubes, one dimensional
nano wires etc and some
bio-material components to
interact with biological

Hardware components in a nanobot
Logic processor/ nano processor
A biosensor is an analytical device, used for the
detection of an analyte, that combines a biological
component with a physicochemical detector.
The sensitive element may be biological or bio
mimetic component that interacts the analyte
The transducer or the detector element converts
these signals into a form which can be easily
processed and quantified by the logic unit.
Different kinds of actuators such as
electromagnetic, piezoelectric, electrostatic and
electro thermal etc..
ATP, DNA and RNA can be used as a biological
alternative for nanomotors.
Fullerence with CNT as conductive structures
permits electrostatically driven motors providing
the force necessary for micromanipulation
Blood flow Body heat
Principle of inductive coupling
Acoustic, chemical, light and Radio frequency are possible
Chemical signal useful for short range communication
Acoustic signals are more suited for long range
Resolutions of 700nm can be achieved by using acoustic
Transmission through RF @ 4.5 KHz frequency
Transmission through sonar:-20uW@8Hz for 3V supply
First programmable logic processor manufactured my MITRE corp
in association with Harvard university in 2011

Multiple arithmetic and logical functions can be implemented on the
Each ‘tile’ consist of precisely engineered and fabricated Si-Ge
nanowires surrounded by insulating metal oxides
Operating speed achieved:-100 MHz, speeds achievable in future:-
Transistor length:-20nm, 10nm for CNT

ABF OR ARTIFICIAL BACTERIA
Developed by university of Zurich, Switzerland
Total length is around 20 micrometers
Fabricated by vapor depositing ultra thin layers of gallium, indium, arsenic and
chromium on substrate and are then patterned from it through lithography
This form super thin narrow ribbons that curl themselves into a spiral shape
when detached from substrate
Thickness and composition of the deposited layer defines the size and shape of
Propulsion via magnetic field, applied to the Cr-Ni-Au ‘head’ of the robot.
FABRICATION STEPS AND STRUCTURE
ABF IN ACTION
Project officially launched in the year 2014
multiple sets of nanoparticles capable of identifying specific
diseases and anomalies stored in a MEP. And delivered through IV.
These nanoparticles, once released into the blood, binds to the

Advantages of nanorobots
Disadvantage of nanorobots
Hardware and control techniques
are still in its infancy and are not
ready for commercial prime time
Technology can be reverse
engineered by hostile organizations
to the molecular level and wreck
havok on the unsuspecting public.
Nanorobots are highly useful in the field of medicine
Advancements in STM, SEM help to build nano-scale
CNT based FET’s can pave way for a whole new levels of
nanocomputing in the future and thus pave way for a Fully
