This document outlines a technical seminar presentation on nanorobots. It discusses how nanorobots could be used in nanomedicine, with sections covering their potential appearance and sizes, methods of control and navigation using external systems like magnetic fields, power sources using chemicals in blood, locomotion through vibrating or magnetic manipulation, applications like targeting cancer cells or breaking up stones, and a conclusion that nanorobots could eliminate diseases and extend human abilities.

3. Introduction
 The term “Nanotechnology” generally refers to engineering
& manufacturing at nanometer length scale.
 The possibility of nanorobots was first proposed by Richard
Feyman in 1959.
 Nanotechnology gives us specially engineered drugs which are
nanoscale cancer seeking missiles.
Nanomedicine is the process of diagnosing, treating and
preventing disease and traumatic injury of relieving pain and of
preserving and improving human health using molecular tools and
molecular knowledge of the human body.

4. Nano-biotechnology
Nano-biotechnology is rapidly advancing technology that
applies the tools & processes of microfabrication to build
devices to study biosystem.
The research and development of nanorobots with
embedded nanobiosensors and actuators is considered a
new possibility to provide new medical devices for
doctors.

6. Appearance
It is impossible to say exactly what a generic nanorobot
would look like.
Each species of medical nanorobot will be designed to
accomplish a specific task, and many shapes and sizes are
possible.
Each nanorobot will be on the order of perhaps 0.5 micron
up to perhaps 3 microns in diameter.

7. Control
 Because of the small dimensions of the Nanorobots, on board
computation will be limited. One solution to that problem is to
do the computation on a central computer that receives sensor
data from the Nanobots and sends them orders.
To help control nanorobot position, a system for tracking an
object in space can comprise a transponder device connectable
to the object.
 The transponder device has one or several transponder
antennas through which a transponder circuit receives an RF
(radio frequency) signal.

8. Navigation
 External navigation systems might use a variety of different
methods to pilot the nanorobot to the right location. One of
these methods is to use ultrasonic signals to detect the
nanorobot's location and direct it to the right destination.
 Using a Magnetic Resonance Imaging (MRI) device, doctors
could locate and track a nanorobot by detecting its magnetic
field.
 Doctors might also track nanorobots by injecting a radioactive
dye into the patient's bloodstream.

10. Powering the Nanorobots
 A Nanorobot with mounted electrodes could form a battery
using the electrolytes found in blood.
 Nanorobots could get power directly from the blood stream.
 The Nanorobot would hold a small supply of chemicals that
would become a fuel source when combined with blood.
 A nanorobot could use the patient's body heat to create powe.

11. Locomotion
 The scientists manipulate the arms by creating magnetic
fields outside the patient's body.
 The magnetic fields cause the robot’s arms to vibrate,
pushing it further through the blood vessels.
 Another potential way nanorobots could move around is
by using a vibrating membrane. By alternately tightening
and relaxing tension on a membrane, a nanorobot could
generate small amounts of thrust.

13. Application
 It is clear that very "simple" medical Nano devices can have
extremely useful abilities, even when applied in relatively
small doses.
 Heart attack coagulation, kills cancer cells, operates the
tumor.
 Kidney stones.
 Liver stones.
 In mechanical field these can be used to study the
microstructure of a metal by mixing nanorobots with
lubricating oil or required solution.

14. Conclusion
Nanorobots in medicine will eliminate virtually all
common diseases of the 20th century, virtually all
medical pain and suffering, and allow the extension of
human capabilities most especially our mental
abilities.
