The kinematics of manipulators is a central problem in the automatic control of robot manipulators. Theoretical background for the analysis of the 5 Dof Lynx-6 educational Robot Arm kinematics is presented in this paper. The kinematics problem is defined as the transformation from the Cartesian space to the joint space and vice versa. The Denavit-Harbenterg (D-H) model of representation is used...

We develop a consistent procedure for testing the adequacy of parametric time series models. The approach is to extend Herman Bierens’idea of examining the covariances between regression residuals and an exponential weight function, to check the full range of orthogonalities predicted for the score contributions in quasi-maximum likelihood estimation. Tests of this type, which involve nuisance ...

© Appl. Rheol. 20 (2010) 63293 DOI: 10.3933/ApplRheol-20-63293 Abstract: Bitumen is undoubtedly the most important material in the construction and rehabilitation of flexible road pavements. By increasing the temperature, bitumen changes from brittle solid, to viscoelastic solid and finally to Newtonian fluid. The rheological characteristics of bitumen also vary greatly due to aging, which is a...

Choices involving tradeo¤s of bene…ts and costs over time are pervasive in our everyday lives. The observation of declining discount rates in experimental settings has led many to promote hyperbolic discounting over standard exponential discounting as the preferred descriptive model of intertemporal choice. In this paper, I develop a new framework that directly models the intertemporal utility ...

A method to simulate digital human running using an optimization-based approach is presented. The digital human is considered as a mechanical system that includes link lengths, mass moments of inertia, joint torques, and external forces. The problem is formulated as an optimization problem to determine the joint angle profiles. The kinematics analysis of the model is carried out using the Denav...

In the present paper, an attempt has been made to carry out kinematic and dynamic analysis of a six-legged robot. A three-revolute (3R) kinematic chain has been chosen for each leg mechanism in order to mimic the leg structure of an insect. Denavit–Hartenberg (D-H) conventions are used to perform kinematic analysis of the six-legged robot. The direct and inverse kinematic analysis for each leg ...

En este trabajo se presenta la implementación de un dispositivo, integrado por modelo robot a escala obtenido mediante impresión 3D tipo FDM (Fuse Desposition Modeling) tomando como base ABB IRB 460 industrial y una tarjeta programable Arduino UNO R3, el cual puede ser utilizado para enseñanza robótica nivel superior. Para ello obtuvo cinemático del escala, uso dispositivo prueba cuando no es p...

Background The Centre of Pressure Progression (COPP) is thought to be a useful measure of dynamic function of the foot [1]. The COPP has been used as an outcome measure in flat foot surgery, with an improved COPP defining a successful surgical result [2]. It is, however, unclear how the COPP varies in children with flat feet (FF) compared to those with normal arches (NA) and how this relates to...

IR communications have im quest of present day bandwidth hungry applications. jects, i.e. no interference from other light sources in the velength in the adjacent rooms, building etc [1-4]. The u IR wireless communication only prevents multipa...
