Forward kinematic solution and its applications for a 3-DOF parallel kinematic machine (PKM) with a passive link

Robotica, 2006
In this paper, a 3-DOF parallel kinematic machine (PKM) with a passive link is introduced. The forward kinemaic model is established, and a new technique is proposed to solve this model. The developed forward kinematic solver (FKS) is employed in two new applications: the determination of joint workspace and sensor-based real-time monitoring.

Design of length measuring system for Stewart platform using new forward kinematics solution

2010 11th International Conference on Control Automation Robotics & Vision, 2010
In this paper, based on new presented approach for forward kinematic problem, length measuring system for Stewart platform is designed. The analysis is performed by using a software platform which models the system dynamics and control. A typical feedback linearization method is used to design the controller system and performance of designed ...

Forward and Inverse Kinematic Solutions of a New Three Dimensional Metrology Frame

Manufacturing Science and Engineering: Volume 2, 1997
Abstract A concept for a three dimensional, non-contacting metrology system is presented. Both the forward and the inverse kinematics solutions for the system are developed using a line geometry, resulting in an efficient representation that may describe a general assembly of the kinematic system and error parameters determined through ...

Solution to the forward instantaneous kinematics for a general 6-DOF Stewart platform

Mechanism and Machine Theory, 1992
Abstract In this paper a method is presented for solving the forward instanteneous kinematics of a general 6-DOFStewart Platform. The method, which is general and easy to implement, is based on the velocities of three non-collinear points of the end effector.

Solution of forward kinematics model of six degrees of freedom parallel robot manipulator

Proceedings of the IEEE Symposium on Emerging Technologies, 2005., 2005
Mathematical models for six degrees of freedom (DOF) parallel robot manipulator have been developed and described in this paper. These models deal with the statics and kinematics of the manipulator. The static part is concerned with the structural analysis of the manipulator. The kinematics covers both the forward and inverse kinematics problems of the

The estimation for forward kinematic solution of Stewart platform using the neural network

Proceedings 1999 IEEE/RSJ International Conference on Intelligent Robots and Systems. Human and Environment Friendly Robots with High Intelligence and Emotional Quotients (Cat. No.99CH36289), 2003
This paper introduces a kind of the forward kinematic analysis, which finds the 6-DOF motions from a given six cylinder lengths in the Stewart platform. In the case of a parallel manipulator, while the solution of the inverse kinematics can easily be found by the vectors of the links which are composed of the joint coordinates in base and plate frame ...

Comments on "Closed form forward kinematics solution to a class of hexapod robots"

IEEE Transactions on Robotics and Automation, 1999
The paper above by Yang and Geng (1998) presents a class of parallel manipulators that has an efficient closed form solution to its forward kinematics. This Correspondence points to some missing insights in that paper (and in many others), especially with respect to singular configurations.

A direct numerical solution to forward kinematics of general Stewart–Gough platforms

Robotica, 2006
This paper presents a simple numerical method for forward kinematics of general Stewart–Gough platforms, which can generate a unique solution directly. This method utilizes the trivial nature of the inverse kinematics of parallel manipulators, and derives a straightforward linear relationship between the small change in joint variables (leg lengths ...

Wavelet Based Neural Network Solution for Forward Kinematics Problem of HEXA Parallel Robot

2008 International Conference on Intelligent Engineering Systems, 2008
Forward kinematics problem of parallel robots is very difficult to solve in comparison to the serial manipulators because of the highly nonlinear relations between joint variables and position and orientation of the end effector. This problem is almost impossible to solve analytically. Numerical methods are one of the common solutions for this problem.

Real-Time Solutions to the Forward Kinematics of a 2RSS + RRR Parallel Mechanism

2016
In this paper, we propose a new parallel mechanism designed for haptic interface. The haptic device consists of a 2RSS + RRR parallel mechanism with 3 degrees of freedom. In general, the control of haptic devices requires a high servo rate up to 1 kHz which demands a fast and real-time solution to the forward kinematics. Newton–Raphson method is one of
