Nanorobots are tiny machines used to cure diseases in
human or in any organism.
Performs task at nanoscale
The size of nanorobots is 10 -9.
The prefix ‘nano’ means billionth.
WHAT ARE NANOROBOTS?
STRUCTURE OF NANOROBOTS
Molecular sorting rotors
Structure of nanorobots.
Molecular sorting rotors:
Made up of carbon nanotubes.
Nanotube with nanogears used for
changing the direction of movement.
Like that in nanorobots it is used to drive forward against
the blood stream.
Fitted along with the propellers used to propel the device.
Fitted externally and internally with the nanorobots to receive the signal

USE OF NANOROBOTS IN HUMAN BODY
A doctor offers the patient an
injection of a nanorobot.
Seeks out cancer cells and
Dispells the disease at the
source, leaving the healthy cells
The patients has no awareness of devices working inside
NANOROBOTS IN HEART SURGERY
Blood vessels play an important
role in supplying blood
to all parts of our body.
Due to the fatty deposition on
the walls of blood vessels
blood will not move freely to
These leads to heart attacks and damage the vital
Nanorobots use blood flow for its movement.
In order to move the nanorobots,the
blood should be
To satisfy this, nanorobots should be made with electric motors to turn propeller.
• Speed of blood
• Get through the heart without stuck
• React with changes in blood flow rate
• Able to change the direction according to the blood stream
Navigation of nanorobots into blood
Sensors are used to locate the fatty deposits.
To control the nanorobots as per our wish fit the TV camera .
Sensors are used to receive the signals and do the operations
according to signals send by remote control unit.
Nanorobots towards a destination
The fatty deposits (or) clots are removed using special blades fitted with nanorobots.
Continuous (or) pulse signal is used to activate the blades.
View of nanorobot removing the fatty deposit
To take nanorobots from the body we use two methods one is retrace our path
upstream another is making small surgery to remove.
ADVANTAGES OF NANOROBOTS
Rapid elimination of disease.
Nanorobot might function at the atomic and molecular level to build
machines or circuits known as molecular manufacturing.
Nanorobots might also produce copies of themselves to replace worn-
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.
Breaking up blood clots
Breaking up kidney stones
The nanorobots are used in heart surgery, due to this number of risks and side effects
behind is reduced.
The same technique is used in various treatments like cancer, breaking kidney stones,
breaking liver stones, parasite removal only with slight modification.
Within ten year several advancement technologies should be made from this
