Introduction: The RANGER: Prosthetic Leg
Prosthetics are used everyday in almost every single way. Because of this most of the prosthetics seen today are very cheap and made very poorly. On top of this, almost all of these prosthetics are extremely expensive. The RANGER is a prosthetic that is very well made and durable. Yes it may be expensive to make but in the end, it is very worth while. But why is it worth while? this prosthetic is made from airplane grade aluminum which eliminates the fear of the prosthetic breaking under pressure. Also, this prosthetic has the ability to come apart so that storage of it becomes 10 times easier. for example, lets say you wanted to ware a different prosthetic for awhile, you would have the ability to package the RANGER back up in a small condensed manner.
Many people have asked me why did I make the RANGER? To answer this question I need to start explaining what I do as a second hobby. I am dancer with the International Ballet Academy and I have been dancing for about 11 years now. But just this year I was thinking of prosthetics and how I could make them better and potentially useful to dancers. When a dancer goes to do a big jump for example, they put a lot of their body wait onto their legs in order to spring back up. For this reason, I needed a material that could withstand a ton of pressure. That is why I applied airplane grade aluminum to the RANGER. Also the spring function and the articulation of the foot are useful aspects for dancers.
The last and finial question that many of you are probably asking is why am I sharing this with you? The answer is that I want everyone to see that a prosthetic can do more than just walk or run if the creators would just put a little more effort into how they make there prosthetics. For example, airplane grade aluminum is used on airplanes every day and is an obvious resource that is very durable. Despite this fact, manufactures use carbon fiber because it is cheap and inexpensive. Unfortunately carbon fiber prosthetic feet are the cause of many injuries from prosthetics today. This is a life lesson as well. If you spend more time on something you will come out with a better result. Paul J. Meyer said that "productivity is never an accident. It is always the result of commitment to excellence, intelligent planning, and focussed effort." With that said I hope you enjoy building this prosthetic leg and enjoy the video that I have attached.
