INTRODUCTION
1.1 Project Background
This project is developing to design the structure of prosthetic foot and the aim of developing this product is to assist the group of people who have physical disabilities to
gain normal life again. Nowadays, the improvement made to make sure the prosthetic foot to be properly functional and comfortable to user takes lot of time. As known, the
soldier in the military sector is facing a very high risk in losing their limbs during combat. The highest risk is losing their foot. The research of the prosthetic foot was
founded since
World War 1 until World War 2 Erin Strait, E 2006.
During that time, the equipment, material and the research of the prosthetic foot cannot be done as nowadays because the technology have not been achieve yet and because of
that, the United States government made a deal with some military companies to improve prosthetic body parts rather than weapons. In addition, the government
standardized prosthetic training, instead of the previous apprenticeships, as well as increasing funding for engineering research in universities.
Nowadays, the risk of losing limbs does not only come from war, but from health problems where this phenomenon is becoming worse. There are a lot of diseases that
2
could cause the convict to lose their limbs and because of that, the need of prosthetic foot is becoming more important to a society. The research of this prosthetic foot is
focusing in improving the function of the prosthetic limbs to be more efficient and this project is to design and develop a compounded three-link manipulator applied as
prosthetic foot. It focuses on the mechanism design and the expectation on precise mechanical on all parts when the mechanism high M., Renfrow, 2005.
1.2 Objective
This project is carried out with the following objectives. a To design the structure for the prosthetic foot that will be assembled at the actual
foot frame. b To make mechanism development of a compounded three link manipulator applied
as prosthetic foot.
