The first adjustable feed support system in FAST is a six-cable-driven parallel manipulator. Due to flexibility of the cables, the cable-driven parallel manipulator bears a concern of possible vibration caused by wind disturbance or internal force from ...

A Review of Cuspidal Serial and Parallel Manipulators
Abstract Cuspidal robots can move from one inverse or direct kinematic solution to another without ever passing through a singularity. These robots have remained unknown because almost all industrial robots do not have this feature. However, in fact, industrial robots are the exceptions.

On the accuracy of $N-1$ wire-driven parallel robots [PDF]
A $N-1$ wire-driven parallel robot is a robot for which all the $N \ge 3$ wires are connected at the same point of the platform, allowing to control the location of this point. We are interested in the positioning accuracy of such a robot.

Jerk Analysis of the Spine by Means of a Parallel Manipulator [PDF]
In this work the kinematics of the end of the spine is simulated by means of a five-degree-of-freedom decoupled parallel manipulator. The displacement analysis is presented in a semi-closed form solution, whereas the velocity, acceleration and jerk ...

A Fuzzy PID Approach for the Vibration Control of the FSPM
This paper focuses on the vibration control issue of a Flexibly Supported Parallel Manipulator (FSPM), which consists of a flexible support and a rigid parallel manipulator. The distinct characteristic of an FSPM is the dynamic coupling between the rigid

Dynamic Analysis and Trajectory Tracking Control for a Parallel Manipulator with Joint Friction
To overcome the bearing capacity deficiencies of traditional serial hip joint simulators, complex trajectory simulation, among others, as well as a parallel manipulator with two pairs of artificial hip joints and two moving platforms are proposed.

Parallelism and concurrency of graph manipulations
AbstractGraph manipulations are formalized as graph derivations within the framework of graph grammar theory. In this paper we generalize recently published ‘Church–Rosser’ and ‘Parallelism’ Theorems for graph derivations. Given a ‘sequential independent’ sequence of graph derivations G⇒H ⇒X the Parallelism Theorem states that there is also a ...
