When they talk about the iron hand, it is usuallyimply either a simple layout or a bionic prosthesis. The article will explain how the first sample is made and how it is turned into the second one. But before considering how to do an iron hand with your own hands, let's consider what science has achieved now.
About the state of affairs
Even 50 years ago, a man who lost hislegs or arms, could only dream that once he would be able to make up for his loss thanks to scientific developments. And not just to get something, but to be able to function as if the organ is in place. Now the creation of iron hands involved a fairly large number of companies and technology lovers. Simple devices that cannot perform the action of the fingers are simply called prostheses. Whereas those that can capture signals from the human brain and react to them - with bionic hands. Because of the high cost, not everyone can afford such a device, but you can do it yourself. An iron hand with your own hands may not turn out to be as perfect as industrial designs, but even this option is better than nothing at all. And now we offer to get acquainted with how a similar device is built and how it is done.
Device
The usual "cosmetic" iron hand externallyrepeats the outlines of the human. It can be made of plastic and already look like normal, or of metal - in such cases it is usually covered with synthetic leather. The bionic iron arm is arranged in this way: when a person wants to move a finger, the brain sends a corresponding impulse to the muscles. Sensors catch these signals due to the reduction of the surviving muscles. Each sensor is responsible for its "field of activity", so if it captures the impulse, then a certain finger will be reduced. The possibilities of using this technology are wide, and even if the arm was damaged above the elbow, the normal functioning of the prosthesis is carried out without problems.
Installation process
To connect and configure the work of the ironhands, it may take 5-30 days. The time depends on the size of the body part to be replaced, diseases and problems of the patient, as well as his age. Then you need to get used to the new limb and understand how to manage it. Usually this process in young people lasts a week, it can take a month for retirees. But, alas, the use of the iron hand is not always possible. The fact is that if, after the moment of amputation, the limb has passed too much time, then the muscles will atrophy, and then the device will be controlled with considerable difficulty or the signals will be too weak. The iron hand, made with own hands, has those features that it will be necessary to study the anatomical structure of the business, in order to establish and then adjust the placement of this device.
Capabilities
The harder and more expensive the iron arm, theit is more like a human. So, if we discard cosmetic devices and do exclusively bionics, then we can say that the simplest models can usually make only one grasping movement. More complex can do dozens of movements, but the cost of creating such a technique will be much higher. An iron hand, made by hand, can perform several movements or only one. But even at home, you can create a technique that can satisfy the main range of applications.
Cheaper price
The cost of conventional prostheses varies within500 000 - 5 000 000 rubles, and considering their dependence on the price of a currency (for the overwhelming majority of equipment is import), this price can increase significantly. But there is a potential reduction in price - 3D printers. Most of the foreign samples printed in this way can boast a price of 100,000-150,000 rubles. The greatest success was achieved by the Ukrainian Viktor Baklan, who was able to create a bioelectric prosthesis to hold things at the price of only 1500 hryvnia (4500 for our money). This solution is a very effective answer to the question: "How to make an iron 3D hand with your own hands." It also shows that this technology has a significant prospect here.
How to create a "cosmetic" iron hand?
Where to start?Suppose you want to make such a thing as the hand of an iron man. To create its minimum required set - a file, a soldering iron and a desire to work. All this is necessary if it is created from metal. When working with other materials set will change. So, first you need to decide on the parameters of your own hand and make the initial design. And further on it additional components will be already put on. The most important part here is the frame. You can follow certain drawings, developing an already developed concept, or start your own creativity. If there is no desire or opportunity to devote considerable time to this, then the hand of the iron man from paper is the simplest option. True, it is at the same time the least durable.
How to create your own bionic arm?
This item is already more complex.It should be noted that if you do not have enough experience in creating such devices, then it is unlikely to be creative here. Therefore, it will be necessary to fully follow the construction indicated in the topic. To implement the mechanism of movements, you can use servomotors as the most appropriate in terms of volume / power. When working, you will always need to be careful and do everything carefully. An important step is to configure the sensors so that they receive signals for the fingers that follow (this will help you book on the anatomy of the hand). Of course, from the first time everything will not work, so you will additionally have to sharpen and bring the technique to mind, but the result will be able to greatly please.
Conclusion
You, based on the designs presented here,You can develop your own versions of iron hands. They can differ both in appearance and in capabilities and functionality. Of course, at first it will be difficult, but then you will be able to create various designs “for all occasions”. In addition, if the goal was set and the search for how to make an iron hand was started, then part of the path was already passed. It is necessary only not to stop.
