On the Forward Kinematics of Parallel Manipulators

The International Journal of Robotics Research, 1994
In this article we present a novel procedure for the system atic analysis of the forward kinematics of a class of parallel manipulators that generalize the well-known Stewart plat form. The designs comprise a movable platform connected to a fixed base by a set of legs, the lengths of which can be con trolled.

Uncertainty configurations of parallel manipulators

Robotica, 2000
This paper presents a new method of analyzing and calculating the uncertainty configurations of parallel manipulators. The main feature of the method that makes it attractive with respect to the methods available in the literature, is its ability to obtain simplified uncertainty configuration equations. It's very useful in real-time control.

Kinematic Analysis of Parallel Manipulators

1999
A method for the kinematic analysis of parallel manipulators, based on Denavit-Hartenberg formalism, is proposed. This formulation allows to model separately each joint-link train (defined as the consecutive structural elements starting from the origin of the reference frame associated with the base, to the origin of the reference frame of the mobile ...

Stiffness mapping for parallel manipulators

IEEE Transactions on Robotics and Automation, 1990
Mechanical systems containing closed-loop kinematic chains can exhibit special types of singularities that result in a loss of controllability of the element of interest (output link or gripper link). Therefore, it is very important for the designer to be able to predict this type of behavior.

Direct kinematics of parallel manipulators

IEEE Transactions on Robotics and Automation, 1993
The determination of the direct kinematics of fully parallel manipulators is in general a difficult problem but has to be solved for any practical use. Various methods are presented to solve this problem: two kinds of iterative schemes, a reduced iterative scheme, and a polynomial method.

Force Transmissibility Performance of Parallel Manipulators

Journal of Robotic Systems, 2003
AbstractIn this paper, a new force transmission index called the mean force transmission index (MFTI) is proposed, and the force transmissibility analysis procedure is established for parallel manipulators. TheMFTIis an extended definition of the force transmission index (FTI) introduced by the authors previously.

The Design of a Spherical Parallel Manipulator

2026 12th International Conference on Automation, Robotics and Applications (ICARA)
Parallel robots play a significant role in specialized applications. In this study, the forward and inverse kinematic calculations required for the fabrication of spherical parallel robots were derived. In addition, workspace, singularity, simulation and optimization techniques were examined in detail.

Parallel manipulations of octrees and quadtrees

1992
Octrees offer a powerful means for representing and manipulating 3-D objects. This paper presents an implementation of octree manipulations using a new approach on a shared memory architecture. Octrees are hierarchical data structures used to model 3-D objects.
