• Nanotechnology (sometimes shortened to
"nanotech") is the study of manipulating matter on
an atomic and molecular scale.
• Generally, nanotechnology deals with structures
sized between 1 to 100 nanometer and involves
developing materials or devices within that size.
• Robotics is the branch of technology that
deals with the design, construction, operation,
structural disposition, manufacture and
application of robots. Robotics is related to
the sciences of enginnering, electronics,
mechanics and software.
Nanorobotics is the technology of creating
machines or robots at or close to the microscopic
scale of a nanometer (10-9
Nanorobots would typically be devices ranging in
size from 0.1-10 micrometers.
The main element used will be carbon in the form
of diamond nanocomposites because of the strength
and chemical inertness of these forms.
What is Nanobot?
A nanobot is a nanotechnological robot machine, also
called a nanite, which is a mechanical or eletromechanical
device whose dimensions are measured in nanometres.

MEDICAL NANOROBOTIC APPLICATIONS
• Breaking up blood clots
• Cancer therapy
• Parasite removal
• Targeted drug delivery
• Breaking up of kidney stones
• In treatment of Arterioscleriosis
• Neuron replacement
Nanorobots might carry small ultrasonic signal
generators to deliver frequencies directly to kidney
Nanorobots may treat conditions like
arteriosclerosis by physically chipping away the
plaque along artery walls
Nanobot in action
A nanorobot machine
roaming through the
bloodstream, injecting or
taking samples for
of different compounds.
Nanorobots can be used in blood
cell to detect pathogens.
IN SPACE TECHNOLOGY
• Nanorobots can be used to actively
repair damaged suit materials while an
astronaut is in the field
• Measurement of toxic elements in
• Speed up of medical treatment
• Faster and more precise diagnosis
• Minimum side effects
• In medical field we will have microscopic
robots floating in our blood streams fighting
against cancerous cells
• Speed up of medical treatment.
• Faster and more precise diagnosis.
• Minimum side effects.
• These are used to cure many diseases
which are not possible from ancient
• The initial design cost is very high.
• The design of the nanorobot is a very
• Hard to program.
• Limited external control mechanisms.
All of the current developments in technology directs human a step
closer to nanorobots production.
Nanorobots can theoretically destroy all common diseases of the 20th
century, thereby ending much of the pain and suffering.
Although research into nanorobots is in its preliminary stages, the
promise of such technology is endless.
Nanobots are going to revolutionize the medical
industry in future.
Technology may rule us !
