Investigation of the vectored thruster AUVs based on 3SPS-S parallel manipulator

Applied Ocean Research, 2019
As an extremely significant tool, autonomous underwater vehicles (AUVs) obtain corresponding development which is widely used in the oceanographic survey, military applications and ocean investigation. However, it is rather hard to fulfill missions about

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.

Improving the kinematic performance of a planar 3-RRR parallel manipulator through actuation mode conversion

Mechanism and Machine Theory, 2018
The small workspace and complicated singularities severely limit the application of parallel manipulators. The methodology of redundancy is commonly used to eliminate singularity and enhance the kinematic performance of parallel manipulators.

Translational Parallel Manipulators: New Proposals

Journal of Robotic Systems, 2002
AbstractTranslational parallel manipulators are parallel manipulators wherein the end‐effector performs only spatial translations. This paper presents a new family of translational parallel manipulators. The manipulators of this family are independent constraint manipulators.

Manipulabilities Of Serial-parallel Manipulator Systems

Proceedings of the IEEE/RSJ International Conference on Intelligent Robots and Systems, 2005
This paper presents two different ap- proaches of deflning the manipulabilities and resistivi- ties of serial-parallel manipulator systems. In the flrst approach, the manipulability (resistivity) of the serial- parallel structure is dehed by imposing the kinematic constraint on the local manipulabilities (local resistiv- ities), each of which is ...

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)].

Massively Parallel Binary Manipulators

Journal of Mechanical Design, 1999
A Stewart platform in its most general form is a parallel manipulator with six linear actuators connected to the base and the end-effector with spherical joints. We introduce the concept of massively parallel binary system (MPBS), realised by increasing the number of legs beyond six to a very large number and constraining the actuators to be in one of ...
