Design and control of a lowerknee prosthesis

In this thesis, transfemoral amputations and prosthetic knees evolved for transfemoral amputations are investigated and the electronic control unit of prosthetic knees is designed. The first stages of this work contain information about human walking in medical meaning and bipedal walking. Then, definition of transfemoral amputations, leg biomechanics when walking and phases of walking is discussed. After that, prosthetic knee design for transfemoral amputations is mentioned and prosthetic knees developed by worldwide companies are investigated and discussed in details. At the last stage, electronic control unit is designed and produced for prosthesis used by above knee amputees.
