Nanotechnology can enable build the bridges for the human future through the use of microscopic robots comprised of nano-components. Nano-robotics represents the next stage in miniaturization from micro machines. This paper presents certain distinct aspects that are used to achieve a successful nano-robotic system and their three dimensional visualization in real time.The nano-robots or nanobots, is expected to revolutionize the medical industry, with the ability to treat at a cellular level and make medical applications easy and effective.

Thought of Nano-robotics:
Nano-robotics deals with the controlled manipulation of objects with nano meter scale dimensions. As an atom has a diameter of a few Angstroms (1 Å = 0.1 nm = 10-10 m), and a molecule´s size is a few nano meters. Nano-robotics is concerned with interactions with atomic- and molecular-sized objects, and is sometimes called molecular robotics.The fact that enormous amounts of information can be carried in an exceedingly small space ,because in the tiniest cell, all of the information for the organization of a complex creature such as humans can be stored.   

There are some huge questions yet to be answered. How far can we take nano- robotics before it interferes with our basic humanity? Are we in danger of turning ourselves - and future generations - into strange hybrids of man and machine?
However, the ongoing developments of molecular-scale electronics, sensors and motors are expected to enable microscopic robots with dimensions comparable to bacteria.The control design and the development of complex nano-systems with high performance can be well used to help pave the way for future use of nano-robots in bio-medical engineering problems. With the emerging era of molecular engineering, the development of methodologies that enable investigation to make easier automation, and evaluation of new approaches of the nano-worlds and nano-robotics behavior, are expected to have a great impact for an effective development on nano-robotics.
