Definition: 

Definition Nano robotics is the emerging technology field of creating machines or robots whose components are at or close to the scale of a nanometre (10^−9 meters). More specifically, Nano robotics refers to the nanotechnology engineering discipline of designing and building Nano robots, constructed of molecular components .

What is a Nano robot?: 

What is a Nano robot? Following the microscopy definition even a large apparatus such as an atomic force microscope can be considered a Nano robotic instrument when configured to perform Nano manipulation. For this perspective, macro scale robots or micro robots that can move with Nano scale precision can also be considered Nano robots.

Recent developments:: 

Recent developments: Single molecule car Single molecule motor

Single molecule car: 

Single molecule car Recently, Rice University, Houston, Texas, has demonstrated a single-molecule car developed by a chemical process and including Bucky balls for wheels. It is actuated by controlling the environmental temperature and by positioning a scanning tunnelling microscope tip. sensor having a switch approximately 1.5 nanometres across, capable of counting specific molecules in a chemical sample.

Electric motor made from one molecule, 18 atoms: 

Electric motor made from one molecule, 18 atoms In 2011 researchers at Tufts University in Massachusetts have turned A SINGLE BUTYL METHYL SULPHIDE molecule — C5H12S,into an electric motor. The molecule mounts itself on a piece of copper, via adsorption, with the sulphur atom acting as a pivot — and by applying a stream of electrons from a scanning tunnelling microscope, the molecule begins to spin at up to 120 revolutions per second. With a total diameter of just one nanometer . Most importantly, though, the electron microscope is so accurate that single-molecule motors can be turned on and off.

What Nanobots Are Made Out Of : 

What Nanobots Are Made Out Of Nanotechnology doesn’t specify the material the particles come from, so to develop a nanorobot there are literally endless possibilities for its material makeup. Most likely, its primary material may be silicon.

Why silicon?: 

Why silicon? It is strong enough to last flexible enough to be manipulated in various ways.

challenges: 

challenges Power source Manufacturing Bio degradability

Power source: 

Power source Researchers consider it highly likely that when equipped with a thin film of radioactive material, nanobots will be able to fuel themselves on particles released by decaying atoms. This fuel technology is easily scaled down to nano-size. It also proves immensely efficient because with such a self-driven system in place, nanobots would be able to function indefinitely and never require a replacement fuel cell as they would with batteries or solar power.

manufacturing: 

manufacturing One of the primary difficulties is how one goes about building things that are this tiny. In the future, scientists expect to create micro-factories that will pump out legions of nanobots for human consumption.

Bio degradability: 

Bio degradability Silicon electronics are not bio degradable consequently it becomes necessary to find mass-recycling solution for them. Silicon can be recycled into low-grade products like solar cells, but the process is long, complicated, and usually costly.

Work of Pister : 

Work of Pister Up to this point in time, the closest thing to a purely mechanical nanorobot that has ever been created was the work of U.C. Berkeley affiliate Kris Pister . He invented a solar-powered robot that measures only 8.5 millimeters and can walk slowly on two “legs” like humans do.

applications: 

applications the following potential applications were suggested by well-known experimental scientists at the Nano4 conference held in Palo Alto in November 1995 : detection of toxic chemicals, and the measurement of their concentrations, in the environment Cell probes with dimensions ~ 1/1000 of the cell's size Space applications, e.g. hardware to fly on satellites Computer memory Near field optics, with characteristic dimensions ~ 20 nm X-ray fabrication, systems that use X-ray photons Genome applications, reading and manipulating DNA Nano devices capable of running on very small batteries Optical antennas Cancer cells would be identified, removed.
