Abstract: This article outlines the controller design for a specific active transtibial prosthesis. The controller governs the power output of a DC motor attached to a fourbar mechanism and torsional spring. Active power reinforcement ...

Abstract: This paper presents an approach to the profile synthesis of planar, variable joints by combining higher variable joints. The possible permutations of planar, variable joints that change from a rotational to translational ...

Abstract: This paper introduces the underactuated part alignment system (UPAS) as a costeffective and flexible approach to aligning parts in the vertical plane prior to an industrial robotic assembly task. The advantage of the UPAS ...

Abstract: Current industrial XY plotter cutters that use a belt driven gantry for the X motion and media feed for the Y motion do not perform adequately in high precision applications. Mathematical models for these plotter cutters ...

Abstract: In this paper, it is proposed that the central nervous system (CNS) controls human gait using a predictive control approach in conjunction with classical feedback control instead of exclusive classical feedback control ...

Abstract: A powered anklefoot prothesis and its control system were previously designed and built. To evaluate this prosthesis, amputee subject testing was performed. The testing results are analyzed and compared between the powered ...

Abstract: Understanding how variation impacts a multibody dynamic (MBD) system's response is important to ensure the robustness of a system. However, how the variation propagates into the MBD system is complicated because MBD systems ...
