Research in Micro-Nano-Robotics comprises a very broad field and an advanced scientific field highlighting thus the robotic/micro-nano-robotic science and engineering , which has developed and develops technical, technological, measurement/control, inspection micro-nano-robots, robots fulfilling functions vital to human beings, robots delivering ultra-precise medical services, etc. This research, applied in all these areas and other areas still not mentioned, now passes to a higher development phase, in accordance with the development of electronics/microelectronics, mechatronics/micro-nano-mechatronics and computer science/micro-nano computer science, called Micro-Nano-Robotics. Micro-Nano-Robotics, in its evolution, especially in its future evolution, develops in accordance with the development of micro-nanotechnologies and micro-nano-materials, predicting for the future, a „Micro-Nano-Robotics at human anatomy level and generating for the future a population and a humanoid new society . So, we need to define Robotics in general and especially Micro-Nano-Robotics. © 2014, Editura Cefin. All rights reserved.
