TOPOLOGICAL SYNTHESIS OF TRANSLATIONAL PARALLEL MANIPULATORS

Transactions of the Canadian Society for Mechanical Engineering, 2009
For translational parallel manipulators (TPMs), topology synthesis methods that can be found in the literature are mainly based on screw theory, instantaneous kinematics, or group theory. In this work, finite displacement equations are used for the topology synthesis of TPM.

A Control Strategy of a Two Degrees-of-Freedom Heavy Duty Parallel Manipulator

, 2015
The motion accuracy of a heavy duty parallel manipulator is usually low due to time lag and the difficulty to real-time measure the position of the end-effector.

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.

A Translational 3-dof Parallel Manipulator

1998
This paper presents a new architecture of a three degree-of-freedom parallel manipulator that, if properly assembled, exhibits pure translational motion of the output link (platform) with respect to the frame (base). To prove the existence of a pure translational motion a mobility analysis of the manipulator has been carried out.

3RRRS+3RRPS Parallel Manipulator

2016
The combination of rotary and linear actuators in a parallel manipulator is an interesting option to overcome some of its limitations, such as its well-known limited workspace and recurrent problem of singular configurations. This chapter uses screw theory to address the kinematics of a six-degree-of-freedom parallel manipulator provided with a ...

3-RRPS Parallel Manipulator

2016
This chapter reports on the kinematics of a symmetric three-legged six-degree-of-freedom parallel manipulator equipped with a combination of rotary and linear actuators. The introduction of this class of robot manipulators has been a recursive option to avoid the complexity of the forward displacement analysis of the general hexapod.

Architecture Singular Parallel Manipulators

1998
In the classification problem of architecture singular parallel manipulators there is a qualitative difference between the planar and non-planar cases. The classification of planar ones was already given in (Karger, Husty, 1997), this contribution is devoted to the non-planar case.

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 ...
