This paper presents a review of the literature related to the use of redundancy in parallel
mechanisms. Two types of redundancies are considered, namely, actuation redundancy and …

Parallel kinematic mechanisms (PKM) have received particular attention due to their higher
stiffness, increased payload capacity, and agility, when compared to their serial …

Flexure hinges hold several advantages over classical rotation joints, including no friction
losses, no need for lubrication, no hysteresis, compactness, capacity to be utilized in small …

This paper introduces a novel family of singularity-free kinematically redundant planar
parallel mechanisms that have unlimited rotational capabilities. The proposed mechanisms …

This paper presents the design and modeling of a new 6-DOF 8-PSS/SPS compliant dual
redundant parallel robot with wide-range flexure hinges. This robot can achieve either high …

In this paper, a bio-inspired parallel manipulator with one translation along z-axis and two
rotations along x-and y-axes is developed as the hybrid head mechanism of a groundhog …

This paper addresses both modeling and dynamics identification of kinematically redundant
parallel robots. Based on the Lagrangian equations of the first kind and using the coordinate …

This paper introduces two general architectures of kinematically redundant planar parallel
mechanisms. Their kinematic models are analyzed, an analytic workspace determination …

The dynamic formulation and performance evaluation of the redundant parallel manipulator
are presented in this paper. By means of the principle of virtual work and the concept of link …

This paper proposes an analytical compliance-based matrix method to model the quasi-
static, small-displacement response of planar branched flexure-hinge over-constrained …
