Abstract: Abstract. Exoskeleton robots play an important role in assisting human locomotion and healthcare services. This study focuses on the type synthesis issue of a class of unloading exoskeleton mechanisms that reduce the load ...

Abstract: In this paper, a symmetric 3-UPU (U and P represent universal and prismatic joints, individually) parallel mechanism and its variant mechanism under different geometric and assembly conditions are analyzed. Both have two ...

Abstract: This paper aims to present the topological structure design and kinematic analysis of a novel double-ring truss deployable satellite antenna mechanism. First, a new topological scheme and a new rectangular prism deployable ...
