Chapter 1 INTRODUCTION 1.1 Feedback Control of a Prosthetic Elbow Joint: Amputation is taken from the Latin terminology ‘amputare’ meaning to cut out .It is basically a removal of a limb due to medical reasons such as diseases, accidents etc . After this an artificial device (Prosthetics) is provided to fulfill all the desirable needs. Prosthesis is an artificial device that replaces a missing body part which may be lost due any traumatic accidents or medical reasons. In the 19th Century hooks and wooden limbs were used as replacement to fulfill the supporting needs to overcome support as well as the psychological effects experienced during time . Prosthetic Arm is a biomedical device consisting of levers, links, and joints in an open or…show more content…
1.1.1 Cosmetics Prosthesis: This type of Prosthesis mainly deals with the physical appearance rather than the functional aspect. It is satisfied with skin color of patient. Figure 1.1.1: Cosmetic Prosthesis 1.1.2 Body Powered Prosthesis: This type of prosthesis deals with actuators which are connected to a system through cables .This type of prosthesis depends upon the availability and the level of amputation that is required. Figure 1.1.2: Body Powered Prosthesis Table 1.1: Categories of Prosthetic Arm No. Types of Amputation Types of Prosthesis 1 Shoulder Disarticulation From Shoulder Below Elbow 2 Elbow Disarticulation Above Elbow 3 Wrist Disarticulation Below Elbow 4 Finger Amputation Below Elbow Controlling a Prosthetic arm could be done by several ways some of them are through • Invasive methods: Invasive is a process in which an instrument in introduced in the body . In such processes electrodes are implanted inside the body which would receive and implement the process . • Non Invasive method Non Invasion process does not introduce instruments into the body but uses the surface information to get its details and the desired output that is to be…show more content…
These designs vary depending upon the intended use of the hand. A variety of different actuation methods have been used. Previous robotic arm designs have focused on the mechanical issues of the construction and operation of the prosthesis. Most prostheses are controlled using methods that are not intuitive, such as using the contraction of muscles of the opposite arm. No project has been identified that investigates the feedback control of prostheses from the body’s neural network, which is a more natural control. This project attempts to lay the foundation for an arm that can mimic the human arm, with an intuitive method of
