Living a normal life as a cyborg

Disabilities are challenges that can become difficult when people do not understand. When someone is born without limbs or because of an accident he or she live continue to live with a part of their body missing, life can be complicated, especially for those who do not understand. Not everything is lost because science comes to the rescue of those in need. Since praying for a miracle won't cure your physical problems, technology is making huge steps towards replacing prosthetics with robotic limbs.

cyborg is a cybernetic organism (i.e. an organism that has both artificial and natural systems)

The name cyborg was created in 1960 when  Manfred Clynes and Nathan Kline wrote an article on the advantages of the use in human-machine in space. Since then more science fiction was written and illustrated opening a new chapter in the human mind of how a possible future would see people have robotics components in attached to their bodies. It is not all science fiction though, the medical field is rich of artificial parts that are used o improve the patient's conditions with artificial bones or microchips inserted in the in the head to help people with ear loss.

Some people became quite famous for showing the world how their life changed. It looks like challenges are becoming less and less of a problem the further science helps doctors and those in need. Claudia Mitchell suffered a motorcycle accident in 2004 that cost her left arm, making her the first bionic woman. The artificial arm was created by the Rehabilitation Institute of Chicago.



In the video Claudia Mitchell performs a series of tests moving objects of various size, weight and shape with an early prototype of the artificial limb.







The Scottish company Touch Bionics started its journey in Edinburgh where in the last twenty years their progress on artificial limbs has brought them to lead the way in the field. Below a series of images from their latest project the i-Limb Pulse.


This bionic arm can lift up to 200 lbs.







So far the development of artificial arms the most common for costs and practicality. Since an arm is much lighter to install, is will not be under constant pressure like our legs are on a daily basis, but researcher managed to develop lower artificial limbs that can replace those missing. The C-Leg is helping people live a normal life with a high-tech replacement that can assist the person's walking. Slow or fast doesn't matter as this marvel of technology made of titanium and carbon fibers is another landmark for scientists and a better life for those in need.




Cybernetic components aren't only those who are placed inside our bodies or are total replacement of missing body parts. Artificial body parts are also used in the military field to enhance the soldier's performance during conflicts or during normal operations. Exoskeletons are now a reality that will improve the daily operation when dealing with extra weight lifting or stressful combat situations. Lockheed Martin came up with a practical solution that can help anyone perform better their tasks.





Other exoskeletons will perform harder tasks lifting more and more weight or helping even those who are disable. Raytheon SARCO's experiment resulted in something quite amazing and compact that has the potential to become something we can all use on a daily basis.








The Daiwa House Industry Co. created a full robotic suit that looks like something from the movies and it's very close to be sold to the public. The company stated that the suit is useful to be used in the medical field for nursing, rehabilitation and in all those working places where heavy lifting is required. The suit is priced at 400.000 Yen, but it cab be purchased for 40.000 if a buyer can get a subsidy from the Japanese Federation of Organizations of the Disabled Persons in Tokyo.


A lightweight exoskeleton adapted for combat duties is a current project for the US Army.





Another exoskeleton, but more sophisticated has been called the Halo suit.


Japan and South Korea are ahead in the robotic research developing prototypes that simulates the human body.








How far are we from having a full cybernetic creature then if we can half human with artificial parts? Not too far. Artificial Intelligence (AI) is making lots of progresses and software developers have, although fully independent creation like the one from the movie Terminator is not ready yet. One of the biggest challenge is having a power supply that won't affect the performance of the cyborg. There is the need of a small but long lasting battery that can supply power to the machine for a long period.
The iconic figure of Alex Murphy turned into Robocop is another example of cybernetic applications to enhance the biological body in performing tasks that the common human body cannot. Limits are set by the tolerances of our bones, muscles and flesh.








Last, but not least is Steve Austin the main character from the hit tv-show The Six Million Dollar Man played by Lee Major. It was a cult series from the late 70s where an experimental aircraft pilot for NASA would suffer a fatal crash while testing a prototype.

He is the most famous cyborg in popular culture known for his fast running, powerful throws and an eagle sight. From that success the Bionic Woman would follow other adventures of a female cyborg that together with Steve Austin would fight against villains. What was then sci-fi is now reality helping people live their lives better.
