The name cyborg has been in history for more than 40 years, when Manfred Clynes and Nathan Kline helped coin the term in 1960 as "self-regulating human-machine systems in outer space". Since then, the term cyborg (cybernetic organism) has been defined as an organism that has both artificial and natural systems.
This mechanism became popular over the years. Real cyborgs emerged from different sectors in society. One of the first to implement this mechanism is the military where they used prosthetics to aid a number of US soldiers losing limbs in Afghanistan and Iraq. Not only for the purpose of rehabilitation but for enhancing soldiers' effectiveness in battle, which is why exoskeletons were developed.
In the Medical society, implanted technologies were the most common method to repair or overcome the physical and mental constraints of the bodies. Microchips implanted in the brain enable totally blind persons to visualize their environment by allowing brain signals in the mid-cortex to communicate with an interface. Brain chips also enable robotic arms and legs to move by the power of thought. Other implants like retinal, ear implants and radio implants also made good reputations.
Cyborgs also became famous in movies. Fictitious characters in "Terminator", "The X-Men", "Star Wars" and anime movies were made popular because of their artificial "super-abilities".
Categorically, real cyborgs can be both human and robot. Either way, a cyborg is always human regardless of what makes him a robot.
