BRAIN CONTROLLED ARTIFICIAL LEGS ABSTRACT: This paper describes a brain controlled robotic leg which is designed to perform the normal operations of a human leg. After implanting this leg in a human‚ the leg can be controlled with the help of user’s brain signals alone. This leg behaves similar to a normal human leg and it can perform operation like walking‚ running‚ climbing stairs etc. The entire system is controlled with the help of advanced microcontrollers and digital signal processors.

We are using low frequencies to work the muscles similar to exercise. The electrodes will work be passing a current from the positive electrode to the negative electrode via the muscle‚ this will cause the muscle to contract and then expand when the current has passed. This works the muscle like exercise and leads to increased blood flow. The device will use square wave

It may be in the form of wrist watch or in the pocket‚ from that one wire will go into the heart through the vein. * The electrodes are called endocardiac electrodes and are applied to the heart by means of an electrode catheter with electrode’s tip situated in the apex of the right ventricle. These are in contact with the inner surface of the heart chamber. * It does not necessitate the open chest surgery. *

How Does This Thing Work? It operates on a 100 year old proven technology called electrolysis. Whenever you place two pieces of metal in water‚ and apply electricity‚ the water separates into it’s basic molecules‚ Hydrogen and Oxygen (H2O). If you look at the picture on the left‚ you will see H2O molecules connected together in their liquid form which is WATER But when you apply electricity (from your car battery)‚ the molecules separate and form a GAS (called HHO) which is a mixture of

The equivalence points of acid - base titrations can be estimated from the colour change of chemical indicators‚ such as phenolphthalein‚ methyl red‚ methyl orange and so on. The choice of an indicator

ambiguity. Hertz observed that shining ultraviolet light on electrodes causes electric sparks (electrons being released) more rapidly. Since light was predominately now thought to just be a wave‚ three main objections were raised in regard to Hertz’s observation of this now-called photoelectric effect. In 1914‚ Robert Millikan noticed that there was a cutoff frequency‚ ‚ at which no more electrons are shot out of the conducting electrodes (this work won him the 1923 Nobel Prize). Other experiments

Shielded Metal Arc Welding (SMAW) is the most widely used welding process in the small scale industries‚ because of its low cost‚ flexibility‚ portability and versatility. Shielded metal arc welding is one type of welding process which uses consumable electrode consist of filler core rod coated with chemicals that will help during welding by providing flux and shielding. This process give pure and clean weldment that has high material deposition rate compared to traditional welding process. The SMAW welding
