Enumeration of parallel manipulators

Robotica, 2009
SUMMARYIn this paper, we present a new method of enumeration of parallel manipulators with one end-effector. The method consists of enumerating all the manipulators possible with one end-effector that a single kinematic chain can originate. A very useful simplification for kinematic chain, mechanism and manipulator enumeration is their representation ...

Mobile 6‐SPS Parallel Manipulators

Journal of Robotic Systems, 2003
AbstractIn this paper some special constructions of 6‐SPS parallel manipulators are presented whose platforms, with fixed actuators, are shaky in all possible positions and consequently mobile within their prospective workspace—a behavior which has been called “architectural mobility.” Constructions of such manipulators should be known to the designer ...

Sequence Manipulation Using Parallel Mapping Networks

Neural Computation, 1991
We describe a parallel mapping matrix that performs several types of sequence manipulations that are the building blocks of well-known phonological processes. Our results indicate that human phonological behavior can by modeled by a highly constrained connectionist architecture, one that uses purely feedforward circuitry and imposes tight limits on ...

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.

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.

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 ...
