Nanorobotics:

Nanorobotics is the technology of creating machines or robots in a microscopic scale or close to it. Nanorobotics refers to the still largely hypothetical nanotechnology engineering (designing and building nanorobots). Nanorobots would be about 0.1-10 micrometers and made of nanoscale or molecular components. Nanorobots in this day and age are hypothetical as no artificial non-biological nanorobots have so far been created.Nanorobots would be able to make any structure, including itself, by atomic-scale “pick and place” (a set of nanoscale pincers would pick individual atoms from their environment and place them where they should go). With nanorobots being microscopic in size you will need to have “swarms” which are capable of replication in its environment to be able to work together to get the job done. If nanorobotics were ever used it will be for medical purposes, for example it will be used to molecularly repair the human body, identify cancer cells and eliminate them, repair damage on structures and remove excess waste from the brain to bring the body to a youthful state. Also nanorobotics can be used in those who have been cryogenically been frozen, but yet this is still a work in progress. Nanotechnology has been also been pinned to be used in other areas, such as clothing, sun screen lotions and medicinal nanoparticles which help deliver drugs to targeted tissues and areas of the body.The issues concerned with nanorobotics is that the values of human life and what the society is willing to allow and not allow that is concerned with nanotechnology (replacing human body parts with man-made machinery). Also the fact that nanotechnology has a potential chance of being used for the wrong cause and for unintended consequences.Credits to:
