Kinematics and diferential kinematics of binocular robot heads
Proceedings 2006 IEEE International Conference on Robotics and Automation, 2006. ICRA 2006., 2006This paper presents an analysis of the kinematics of a binocular head, and a new formulation of its differential kinematics using the conformal geometric algebra framework.

A mathematical discussion is presented of eye positions and eye movements in terms of quaternion theory. An eye movement may be regarded as a rotation of the eye about an axis through the center of rotation. The parameters of the axis of rotation and the extent of the rotation are associated to form a higher complex number, and this leads to the ...

Historical . That the problems of plane kinematics should have been studied for a long period is natural; they present themselves quite easily, and in simple fashion. At the end of the seventeenth century, and the beginning of the eighteenth century, De La Hire investigated roulettes, and to him also is due the ...

Compensation of kinematic errors using kinematic sensitivities
Proceedings, 1989 International Conference on Robotics and Automation, 2003Two approaches for the compensation of the position and orientation errors of robot manipulators due to variations of geometric parameters are considered. The first approach is based on the correction of the joint displacements obtained by using nominal inverse kinematics for desired position and orientation, while the second approach is based on ...

Kinematics of parallel kinematic machine Exechon
2009 International Conference on Information and Automation, 2009Due to the potential advantages of heavy load, high speed, and high precision, hundreds of parallel kinematic machines have been proposed. However, only a few of them have been practically applied, and one of the recently-developed parallel kinematic machines is the Exechon machine tool.

In this chapter, we continue the study of kinematics by considering in more detail the motion of fluid parcels, by deriving expressions for the areal, volumetric, and mass flow rates across lines and surfaces drawn in a fluid, and by developing numerical methods for evaluating kinematic variables of interest in terms of derivatives and integrals of the

Connection Science, 2011
This paper focuses on adaptive motor control in the kinematic domain. Several motor-learning strategies from the literature are adopted to kinematic problems: ‘feedback-error learning’, ‘distal supervised learning’, and ‘direct inverse modelling’ (DIM).

Kinematic Influence Coefficient and Kinematics Analysis
2012The concept of kinematic influence coefficient (KIC) of mechanism was proposed by Tesar et al. [1–4]. Benedict and Tesar [1, 2] proposed a completely general model formulation using first- and second-order KIC. This theory has been extensively applied to both open-loop and closed-loop planar mechanisms [3].

We begin the study of fluid mechanics by pointing out the differences between fluids and solids and by describing a fluid flow in terms of the motion of elementary fluid parcels. As the volume of a parcel becomes infinitesimal, the parcel reduces to a point particle and the average velocity of the parcel reduces to the local fluid velocity computed ...
