NanoRobotICS
Define Nano?
Objects of the size 10-9.
1nm is equal to 1 millionth of 1mm.
A nanometer is a billionth of a meter, that is; about 1/80,000 of the diameter of a human hair, or 10 times the diameter of a hydrogen atom.
NanoTechnology
Nanotechnology is a new science that deals with manipulating materials at atomic or molecular level.
Nanotechnology is moving fast towards nanoelectronics fabrication.
Chemically assembled electronic nanotechnology provides an alternative to using a complementary metal oxide semiconductor (CMOS) for constructing circuits with feature sizes in the tens of nanometers.
Applied in construction of Nano Materials
Applied in Molecular NanoTechnology
Applied in NanoRobotics and many more….
Nano Materials
Stain Resistant clothes using nano fibers
Nano Materials
Protective nano paint for cars
Water and dirt repellent
Resistant to chipping and scratches
Brighter colors, enhanced gloss
In the future,
could change color and self-repair?
Nano Circuitry
Two Approaches:
1)Attach metal etc. after structure is built
2)Let structural self-assembly and functionalization occur simultaneously
People are showing promising results from both methods
Nano Media
Nano Coatings
Preventing Viruses from infecting us
NanoRobots
A NanoRobot is a tiny machine designed to perform a specific task or tasks repeatedly and with precision at nanoscale dimensions, that is, dimensions of a few nanometers (nm) or less, where 1 nm = 10-9 meter.
NanoRobots might function at the atomic or molecular level to build devices, machines, or circuits, a process known as molecular manufacturing.
NanoRobots might also produce copies of themselves to replace worn-out units, a process called self-replication.
Robert Freitas
Approaches
Biochip
Joint Use of NanoElectronics, photolithography and new biomaterials.
Nubots
Nubot is an abbreviation for "nucleic acid robots."
Positional Nanoassembly
Using Mechanosynthesis.
Bacteria Based
Based on Micro organisms.
Open Technology
Uses NanoBio-Technology
RESEARCH OBJECTIVES
NanoRobotics is concerned with:
Design and Fabrication
Programming and coordination of large numbers of NanoRobots
Programmable assembly of nanometer scale components with micro or macro devices or by self assembly on programmed templates.
Issues to be addressed while constructing a NanoRobot
Sensors
Actuators
Propulsion
Communication
Programming and Coordination
Sensors
Devices that exploit the change in conductivity of nanotubes and nanowires are called nanosensors.
It should detect obstacles
It should sense the chemicals present
Actuators
Artificial Molecular Machines
Biomotors
Other nanomachines
Adendoine Triphosphate
A chemical compound that functions as fuel in NanoRobots
Propulsion
Swimming or flying in fluids seems more attractive than walking or crawling on a surface, since most objects are likely to be encountered on a surface.
Bacteria are good examples for NanoRobots because they have sizes on the order of few micrometers and they can move in fluids.
Control
Contollers are typically fully fledged computers
Ex Braitenberg’s vehicle 2b
Communication
Communication among NanoRobots takes place by means of waves, acoustics, electrical or optical signals transmitted through small antennae
Cell and subcellular structures communicate by using molecular recognition
Programming and Coordination
NanoRobot by itself will have limited capablities, but coordinated effort of multitude will produce the desired system level results.
Coordination is required for communicating, sensing and acting.
Construction and working of a NanoRobot
Applications of NanoRobotics
Used in NanoMedicine
Used in Telesurgery
Used in purification of water
Used in Drug delivery
Used in purification of atmosphere and also helps in reducing carbon footprints.
Used in detetction of Chemical and Biological warfare agents
In Near Future???
Human Shaped NanoRobots!!
Common Terminologies Used in NanoRobotics
Atomic Force Microsope
Conclusion
Currently, a variety of research is being performed on NanoRobotic devices.
Few industrial products exist right now.
The possibilities are endless, but will take time to develop.
