The purpose of this paper is to review the phenomenon of nanorobotics at a might apply to micro and nano scale robotics is called nanorobotics. These miniature robots have unique advantages such as accessing to unprecedented and small areas, increased flexibility, functionality and robustness, and being low cost), adaptive and distributed. Nanorobotics is the technology of creating machines or robots at or close to the microscopic scale of a nanometer (10 −9 meters). More specifically,. As no artificial non-biological nanorobots have yet been created, they remain a hypothetical concept. The names nanobots, nanoids, nanites or nanomites have also been used to describe this hypothetical devices.in this paper is to review some applications of the nanorobotics as like: micro rootics, emerging druge delivery application, health care, bio-medical application, cancer therapy, Brain Aneurysm, communication system, and new future nano technologies. Etc.

This analysis is explained the energy source for working of the robotics operations and also power supplying from the source to the robotics machines. This report is evaluation, discussion and comparison of the potential source of electrical power for robotics machines due to Conventional batteries, fuel cells, ultra capacitors, and solar cells. At present, however, lithium polymer batteries are the only developed; alternatives include batteries, fuel cells and generators, thermoelectric generators, super capacitors, flywheels and even non-storage options such as tethers. Actually robot design is divided into four primary areas: energy storage, actuation, power and control, can result in severe and adverse effects on the system, such as excess weight, size, heat and operational limitations. On the basses of the physical properties of the robotics we want to provide the suitable power/energy supply systems means utilization different energy sources.
