Abstract: A powered lower limb prosthesis using a four-bar linkage mechanism was previously optimized, designed, and fabricated. Preliminary bench testing was conducted to demonstrate that it is capable ...

Abstract: This paper introduces mechanism state matrices as a novel way to represent the topological characteristics of planar reconfigurable mechanisms. As part of this new approach, these matrices will ...

Abstract: This article discusses the design and testing of a powered ankle prosthesis. This new prosthesis mimics nonamputee (normal) ankle moments during the stance phase of gait through the use of an ...

Abstract: This paper outlines the design and testing of a powered ankle prosthesis, which utilizes a four-bar mechanism in conjunction with a spring and motor that mimics nonamputee (normal) ankle moments. ...
