Abstract

The amputees are classified as a person that had lost their leg due to the diseases, in an accident or in battlefields. The amputees are actually struggled in the daily life because they cannot walking or running like normal person. The aim of the project is to redesign the prosthetic leg using the Magnetorheological (MR) Damper as actuator. The previous studies had been studied with the help of the similarity of the normal person’s gait in the previous researches. House of Quality (HoQ), Morphological chart and Weighted Decision Matrix (WDM) were conducted in term of the engineering design process as the main criteria to determine the new design. The observations of the existing product had been made that needed to redesign and reproduce a better solution for the amputees. The 3-bar mechanism had been used in this project to replace the usual 4-bar mechanism that had been developed in the previous design. The analysis had been made as the result to compare between the new design and existing design. Hopefully, the newer design will be improved the human gait that is used by the amputees and also improve the usage of the prosthetic leg in the future.
