This paper focuses on the current state of nanorobotics and its prospects in the near future. We are aware that this is an emerging technology and is still in the experimental stage. However, this technology has raised a lot of concerns like safety, job security and even the hypothesis of the nanobots leading to the end of the world (The Gray Goo). Many years ago, this technology was basically just an idea but modern science and technology capabilities have proven that these machines can be transformed from idea to reality. Extensive research is currently being carried out in various fields on how to apply this technology, the biggest of which is in medicine. The concept of nanomedicine will be discussed more in a later section of this paper.

According to the interview with Adriano Cavalcanti “On Medical Nanorobotics Feasibility”, November 2005, Fantastic Voyage, he noted that the scientific film and book directed by Richard Fleischer and written by Isaac Asimov (Bantam Books, 1966) was influenced and inspired partially by the lecture given by physicist and Nobel prize winner Richard Feynmann at an American physical society meeting at Caltech on December 29, 1959 titled “There’s plenty of room at the bottom”, which considered the possibility of what later became known as “nanotechnology and nanorobotics”. This film is about a near death of a scientist caused by an assassination attempt. To save his life, a special motorized vehicle with scientific crew was reduced to a microscopic size or “nanosize”; then injected into his blood stream to search and destroy a blood clot. It is evident that in real life, human beings cannot be miniaturized and injected into the blood stream to perform such a task. Thus, this engendered the idea of creating nanorobots with the help of Nanotechnology to perform such tasks and this has become a center of interest and research for many scientists.
WHAT IS NANORBOTICS?
According to Lynn Foster, Nanotechnology is the “manipulation and control of matter in the nanometer scale.” (Lynn foster, 2005:40). A nanometer simply means 10-9m which is a billionth of a meter. Advancement in nanotechnology has led to the research and development of Nanorobotics. Nanorobotics
Nanorobotics, is an emerging technology and a robot engineering discipline of nanotechnology still under the research and development phase. It is basically the development and building of robots in the nanometer scale. It deals with the interaction of atomic and molecular sized objects and sometimes referred to has Molecular Robotics. The future role of Nanorobotics is to create, build and manufacture hypothetical devices such as nanorobots, nanoids, nanites, or other functional devices made of assemblies of nanoscale or molecular components ranging in size form 0.1 – 10 micrometers.
The field of study of Nanorobotics can be categorized into two major areas: The first is the design program, simulation, coordination and control of large numbers of nanodevices or nanoscale machines. However, due to the difficulties in fabricating Nanrobots and other functional nanodevices, current research carried out in this area remains hypothetical or theoretical.
