Inverse dynamics of a parallel manipulator

Journal of Robotic Systems, 1994
AbstractPresented is an analysis of the kinematics and the inverse dynamics of a proposed three degree of freedom (dof) parallel manipulator resembling the Stewart platform in a general form. In the kinematic analysis, the inverse kinematics, velocity, and acceleration analyses are performed, respectively, using vector analysis and general homogeneous ...

Analytic Jacobian of in-parallel manipulators

Proceedings 2000 ICRA. Millennium Conference. IEEE International Conference on Robotics and Automation. Symposia Proceedings (Cat. No.00CH37065), 2002
A general formulation to obtain an analytic Jacobian matrix for in-parallel manipulators has not been developed yet, although several authors addressed it. This paper suggests a consistent approach to obtain the instantaneous kinematic relation of in-parallel manipulators, by extending the results of screw theory to the forward and inverse ...

Micro teleoperation with parallel manipulator

Proceedings. 2000 IEEE/RSJ International Conference on Intelligent Robots and Systems (IROS 2000) (Cat. No.00CH37113), 2002
In this paper, we discuss about micro teleoperation with haptic interfaces. We developed the micro teleoperation systems for micro tasks, such as assembly or manufacturing. We show about structure of master/slave manipulators, its control and experimental results of teleoperation with the manipulators in this paper.

The free mobility of a parallel manipulator

Robotica, 2006
Singularities of a manipulator have been addressed repeatedly. However, the singularities and the degree(s) of freedom, as a matter of fact, are two different aspects of the mobility of a manipulator. Consequently, this paper dedicates to discussing the mobility properties through mobility space, which synchronously define the type, number and ...

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.
