Manipulability and Static Stability of Parallel Manipulators

Multibody System Dynamics, 2003
In earlier papers, P. Maisser developed a systematic analytical approach for the derivation of kinematic relationships of holonomic (geometric) constrained mechanical systems (CMS) [\textit{P. Maisser}, Z, Angew. Math. Mech. 71, No. 4, 116--119 (1991); Nonlinear Anal., Theory Methods Appl. 30, No. 8, 5127--5133 (1997; Zbl 0908.70007)].

Dynamic Control of Parallel Manipulator

2013
Parallel manipulator with longer legs and heavy load is applied in most of the current high fidelity simulators, which is used to simulate various motions in different environments by exporting varying displacement and orientation.

Direct manipulation of parallel coordinates

CHI '00 extended abstracts on Human factors in computer systems - CHI '00, 2000
This paper introduces two novel techniques to manipulate parallel coordinates. Both techniques are dynamic in nature as they encourage one to experiment and discover new information through interacting with a data set. The first technique, polyline averaging, makes it possible to dynamically summarise a set of polylines and can hence replace ...

Accuracy of four parallel manipulator

2012 First National Conference for Engineering Sciences (FNCES 2012), 2012
The Due to the error, parallel manipulators always exhibit some position and orientation errors at the mobile platform. The analysis of accuracy is carried out to find the source errors which affect the pose accuracy of the end-effecter in terms of the error model.

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.
