In America for two patients, a Robotic arm has been successfully tested. This arm will move when patient would want to move or when he would think about any work (Source 1). In America, after fifteen years, a paralyzed woman took coffee without any human or external help. This happen when 58 years old woman patient thought about the coffee, the installed sensors in the brain ordered the robotic arm to do this because the entire body bellow the neck of the patient was paralyzed for several years.
The robotic arm delivered the flask of coffee to the patient’s lips. After that patient by the signals of eye and thinking in mind, gave the pen to the robotic arm and ordered to write “I couldn’t believe that after several years, I am taking coffee without anyone’s help. Further she said that I was almost in state dying but now I feel that I can self dependent. Now there is no need that two to three people reserve for me. Now I can do anything which I want to do. There are now no limits for me. This kind of Robot is first in the history of world. It is hoped that this will revolutionize the life of Paralyzed or wounded people.
This successful robotic arm and sensors are the technological innovation of the experts from the U.S state of Massachusetts. In the scientists team Dr John Donoghue, specialist of brain, from the University of Brown, said this is really time for happiness and proud. In addition he said, this is the greatest achievement in the field of mutual relationship between mind and computer. Because of this invention, people get the power to do anything for that people were unable since years. We believe, this would be very helpful for those people who lost their whole body because of paralysis but their mind is working properly (Source 2).
In this technique, the power to work of robotic arm moves the neurons in the specific part of mind. The electric movements arise and they are sent in computer via wire. Form where the orders are translated and gave instructions to the robotic arm. In 2006, the experts teams published in’ Nature Magazine’ that like this a machine will be discovered which will work with the collaboration of nervous system and paralyzed people would be able to control the cursor the of computer(Source 3).
Paralysis: it is state of patient in which some or most part of the body is unable to work. This happen due to damage of nervous system or more specifically spinal cord. This leads to the failure of muscles (Source 4).
