Abstract: This paper presents the design of a passive two leg orthosis to gravity balance human legs for use by subjects with both leg impairment. This design combines the use of auxiliary parallelograms ...

Abstract: In this paper we present a workspace analysis methodology that can be applied for optimal design of cable-suspended planar parallel robots. The significant difference between regular parallel ...

Abstract: Gravity balancing is often used in industrial machines to decrease the required actuator efforts during motion. In this paper, we present a new design for gravity balancing of the human leg ...

Abstract: A sit-to-stand assist device can serve the needs of people suffering from muscle weakness due to age or disabilities that make sit-to-stand a difficult functional task. The objective of this ...
