Forward Kinematics of Nonpolyhedral Parallel Manipulators

Journal of Mechanical Design, 1993
Forward kinematics has been studied for polyhedral parallel manipulators. We present here an algorithm for the forward kinematic of nonpolyhedral manipulators the plates of which have a symmetry axis. We show that there will be at most 352 possible solutions and exhibit a configuration with eight solutions.

Head-Neck Kinematics in Dynamic Forward Flexion

SAE Technical Paper Series, 1998
<div class="htmlview paragraph">Two-dimensional film analysis was conducted to study the kinematics of the head and neck of 17 restrained human volunteers in 24 frontal impacts for acceleration levels from 6g to 15g. The trajectory of the head center of gravity relative to upper torso reference points and the rotation of head and neck relative to

Forward Kinematics: Making Things Walk

2011
The previous chapters covered the basics of interactive JavaScript animations using the canvas element, and even some advanced “basics.” Now, we branch off and explore some other interesting techniques that use kinematics.

Kinematic Synergy Adaptation to Microgravity During Forward Trunk Movement

Journal of Neurophysiology, 2000
The aim of the present investigation was to see whether the kinematic synergy responsible for equilibrium control during upper trunk movement was preserved in absence of gravity constraints. In this context, forward trunk movements were studied during both straight-and-level flights (earth-normal gravity condition: normogravity) and periods of ...

On the forward kinematics of cable-driven parallel robots

2015 IEEE/RSJ International Conference on Intelligent Robots and Systems (IROS), 2015
Most cable-driven parallel robots are kinematically over-constrained mechanisms. This results in a non-trivial computation of the forward kinematic transformation. It is well known that the forward kinematics of parallel robots may have multiple solutions and in general the convergence of numerical methods is unknown.

Forward Kinematics for a Parallel Platform Robot

2011
This paper proposes a method to calculate the forward kinematics of parallel link manipulators. We calculate the forward kinematics numerically. The method is simple and can make the computer program easy to write.

Analytical Forward Kinematics for Two Kinds of Typical Tripods Part I: Closed-Form Solutions for Forward Kinematics Methods

2012
The articulated A/B-axis tool heads with parallel structure behave better than the traditional tool heads with serial structure in terms of saving machine processing time and reducing the deformation of the workpiece when they are used in thin wall machining applications for structural aluminium aerospace components.
