Structural Design of Parallel Manipulators With General Constraint One

Abstract

In this paper structural design of parallel manipulators with general constraint one regarding angular and linear-angular conditions are considered. Four known overconstrained mechanisms with angular and two new designs with linear-angular conditions are presented. 14 structural groups and end effector chains in subspace λ = 5 are examined. New formulations and definitions of constructing overconstrained manipulators are described. Using examined structural groups, all architectures of subspace λ = 5 parallel manipulators with revolute joints and single-loop are introduced via structural bonding.
