The design of flexible parallel stages has recently been systematised for the three-dimensional space using screw theory. The relationships between the twists (motions), the wrench actuations, and constraint wrenches spaces ...

A kinematic and workspace analysis of Spherical 3-RRR Coaxial Parallel Robot are developed in this paper. Position and orientation was determined through the inverse and forward kinematics using geometric and numerical ...

This paper presents the higher-order kinematic analyses of a planar parallel robot, addressed by means of the theory of screws. The reduced velocity, acceleration, jerk and hyper-jerk state for the end-effector of robot ...

Abstract : Humanoid robots (HRs) research and development have been increasing in the world due to motion versatility of such robots and also due to the high degree of spatial and environmental adaptability provided by th ...

In this paper, a complete kinematic analysis of a planar 3-RRR parallel robot is presented. The position through the direct and inverse kinematics, velocities, jacobians and accelerations were developed using Screw Theory. ...

We study the diffusion of anti-plane elastic waves in a two dimensional continuum by many, randomly placed, screw dislocations. Building on a previously developed theory for coherent propagation of such waves, the incoherent ...

The present study investigated the utilization efficiency of an intermeshing co-rotating twin-screw extruder (ICTSE) in the devulcanization of natural rubber compounds (NR), evaluating the physical, chemical and mechanical ...
