Workspace characterization and kinematic analysis of general spherical parallel manipulators revisited via graphical based approaches

Autor: Khaled Assad Arrouk, B. Chedli Bouzgarrou, Grigore Gogu

Publikováno v: Mechanism and Machine Theory. 122:404-431

This paper revisits some fundamental issues in kinematic analysis of spherical parallel robotic manipulators (SPRMs), such as the orientation capacities of the mobile platform (MPF), and assembly modes determination. The orientation capacities are an

Publikováno v: EuCoMeS 2018 ISBN: 9783319980195

This paper highlights the use of graphical techniques for workspace characterisation of spherical parallel robotic manipulators (SPRMs). Kinematic analysis of this type of mechanism is revisited through a 3D representation of the orientation operatio
