Summary: | This study proposes a joint simulator to evaluate new prosthesis designs prior to patient trials to minimize the inconveniences encountered in prosthesis applications for amputees. Design and prototype manufacturing of a force-controlled series elastic actuator was realized. In addition, actively controlled trans-tibial and trans-femoral amputation prostheses were designed by utilizing this actuator. A pneumatic joint simulator consisting of a proportional air pressure valve was also designed and manufactured. The experimental results demonstrated that good position tracking performances and effective assistive forces under the simulated walking conditions were achieved. The developed systems have the potential to contribute to the improvement of inadequate features of passive prostheses and to the development of new assistive systems that better respond to the needs of people with orthopedic disabilities. |
