Abstract -Nanorobotics is the technology of creating machines or robots of the size of few hundred nanometres and below consisting of components of nanoscale or molecular size. This paper is about nanorobots and how it is used in medical field to cure diseases. Nanotechnology is an enabling technique that could have an impact on the world that dwarfs the internet’s impact on our daily lives. Nanorobots are manufactured using this nanotechnology. Nanotechnology is not only used in electronics field, apart from that it is going to play an important role in future. Without surgery without drop of blood we can cure the diseases using this awesome technology. In this presentation we are going to discuss about nanorobots that are used in curing diseases. This technology finds a cure for brain tumors, and also for any other unwanted elements in the body like kidney stones, cancer cells etc without any side-effects. The future of technology becomes easier to predict. The technology that works at the nanoscale level of molecules and atoms will be a large part of this future enabling great improvements in all the fields of human presence. In the present work, the compilation of advancement in nanotechnology in context to nanorobots is done. The challenges and issues in movement of a nanorobot and innovations present in nature to overcome the difficulties in moving at nano-size regimes are discussed. The efficiency aspect in context to artificial nanorobot is also presented. Keywords - Nanorobots, powering, navigation, feasibility, revolutionize I .INTRODUCTION

Nanorobotics is the technology of creating machines or robots of the size of few hundred nanometres and consisting of components of nanoscale or molecular size. Nanorobots have dimensions comparable to those of biological cells, and are expected to have remarkable applications in health care and environmental monitoring.When fully realized from the hypothetical stage, they would work at the atomic, molecular and cellular level to perform tasks in both the medical and industrial fields that have heretofore been the stuff of science fiction. Nanorobots are so tiny that they can easily traverse the human body. The main purpose will be maintaining and protecting the human body against pathogens. They can cure skin diseases; be used in mouthwash to identify and destroy pathogenic bacteria, augment the immune system to find and disable unwanted bacteria and viruses; and also getting rid of arteriosclerotic deposits in the bloodstream to widen the affected blood vessels.


Nanorobots are made out of parts from 1 to 100 nanometers, mainly composed of carbon in the diamond/fullerene nanocomposites forms because of the strength and chemical inertness of these forms. The best coating to avoid the immune system attacking them is a passive diamond coating. Building nanorobots involves sensors, actuators, control, power, communications and interfacing across spatial scales and between organic/inorganic as well as biotic/abiotic systems. Anybody that does work that requires precision interactions with nanoscale objects.


Current developments in nanoelectronics and nanobiotechnology are providing feasible development pathways to enable molecular machine manufacturing, including embedded and integrated devices, which can comprise the main sensing, actuation, data transmission, remote control uploading, and coupling power supply subsystems, addressing the basics for operation of medical nanorobots. To help control nanorobot position, a system for tracking an object in space can comprise transponder device connectable to the object. The transponder device has one or several transponder antennas...
