Design of Human Exo-Skeleton Suit for Rehabilitation of Hemiplegic People

摘要

The end of the 20th century witnessed the development of Exo-Skeleton Suits. These suits were fabricated for various reasons and their main focus was to reduce human effort.They were made so that the daily activities of human beings are simplified and therefore to be less stressful. So the advancement of Exo-Skeleton Suits started and were made for areas ranging from defence to medicine. But much focus was given to increase human strength.Even the recent Human Exo-Skeleton Suit HAL(Hybrid Assistive Limb) which is a multi-purpose suit but its primary aim is to reduce human force for work.In this paper the focus is shifted to the paralyzed people especially Hemiplegic people.Hemiplegia is a disorder in which one half of the Human body Fails to perform its functions, including one Arm and one Leg i.e. half of the body is Paralysed. As a result of this, they are not able to walk and do other physical activities .The main reason of Hemiplegia found is due to stroke and in many cases it is hereditary .Recovery from stroke is difficult and the treatment is prolonged hence the Exo-Skeleton Suit-HI is designed and proposed in this paper. Enabling these people to walk using a wearable Exo-Skeleton Suit-Hl, which is cost-effective and will enable walking is the real motive behind the ideology.Hl Suit is designed to focus purely for hemiplegic people unlike HAL which has multi-applications and is extremely costly for a common man. Instead of conventional motors, which are used in earlier Exo-Skeleton Suit for the movement of limbs, Pneumatic actuation is used for better locomotion. The Control of this actuation is done by means of a fixed Potentiometer. The device is tested using Softwares like Festo Fluid Sim and Pro-Engineer which is exhibited in this paper. A Test Case is performed and satisfying Results were obtained. In its Later stages of implementation the similar device will be made for Paraplegia-the medical condition in which both the Legs are Paralysed.
