Prosthetic limbs are composed of three essential factors: firstly the socket which is the fuse between the limb and the mechanical support system, secondly the pylon which changes the magnitude of the lost limb as well may combine a knee/elbow joint in case that the imputation is over the knee/ elbow, finally, an artificial foot/hand. As to the growing rate of imputation, there is an urgent need for prosthetic limbs, and various reinstatement limbs [Erin Strait, 2006]. Hybrid assisting limb (HAL) is a full physique costume to alp degenerated muscles and brain or spine paralyzed people.
It operates using Wi-If and a computer that controls it. It has two control systems: electromyography and bio-cybernetic which reads the electrical signals produced by the muscles [CYBERCAFÉ Inc. , 20091 A Scottish firm developed the I-LIMB hand with five independently mechanized fingers; each finger has a motor which means each finger is individually guided and articulately gesture. It has two electrodes that take up molecular signals which is needed to open and close each finger, [touchiness. Com]. [History’ and future of rehabilitation robotics, march 2, 2010].
Table 1; age distribution of certified prosthetics, 2002 The chart shows the age distribution through 2002, 80 per cent are under 55 years old while the other 20 per cent is 55 years or older in other words to retire within the next 10 years. [Nelson, 16 Issues affecting the future demand for orthodontist and prosthetics: update 2002]. In conclusion, Imagine a piece of technology that let you control an apparatus simply by thinking about. This piece of technology helps people to continue their lives if it in civil or military, I believe that it is one of the most necessary invention in our daily life now a days.
