In this article we derive the equations of motion of a kinematic chain using concepts naturally associated with the special euclidean group. A simple and coordinate-free formula for the kinetic energy of a rigid body is used to express the kinetic energy of an open chain. From this, the dynamical equations in the Lagrangian form follow easily.

Kinematics and Dynamics of Burst Transitions
Journal of Motor Behavior, 2014Subjects (N = 14) were instructed to walk at comfortable walking speed and to start sprinting on an external (visual) stimulus. This is a burst transition. To accelerate maximally, different strategies can be used. The choice for a strategy was hypothesized to be (a) dependent of the body's dynamical status, which is in its turn dependent on the signal

Underlying the study of fluid flow are the mechanical concepts of kinematics and dynamics, where kinematics applies to the description of the motion, and dynamics applies to the causes of the motion. It is first necessary to develop how to describe the motion and then examine the various forces involved in the motion and energy balance.

Kinematics and Dynamics of the Fulleroid
Multibody System Dynamics, 1997This paper presents, besides a new synthesis, the kinematic and dynamic analysis of a complex spatial mechanism, called Fulleroid, which initially has been synthesized on the basis of the generalized Heureka Oktahedron. This mechanism consists of 24 equal triangular bodies interconcected by simple or double rotary joints. It is a highly overconstrained

Learning Arm Kinematics And Dynamics
Annual Review of Neuroscience, 1989In this review I have discussed how the form of representation used in internal models of the motor apparatus affects how and what a system can learn. Tabular models and structured models have benefits and drawbacks. Structured models incorporate knowledge of the structure of the controlled motor apparatus. If that knowledge is correct, or close to the

Nonholonomic kinematics and dynamics of the Sphericle
Proceedings. 2000 IEEE/RSJ International Conference on Intelligent Robots and Systems (IROS 2000) (Cat. No.00CH37113), 2002We consider a complete dynamic model for the "Sphericle", a spherical vehicle that has been designed and realized in our laboratory. The Sphericle is able to roll on the floor of the laboratory and reach arbitrary positions and orientations, through the use of only two motors placed within the rolling sphere.

Kinematic and dynamic responses of the scrum
Computer Methods in Biomechanics and Biomedical Engineering, 2013In a rugby game, the scrum allows to restart a game to restart after a minor infringement. It is an important sequence for physical and psychological domination of the opponent (Quarrie and Wilson ...

Particle kinematics and dynamics
2017We enter the world of three dimensions gently, considering particles which just have mass, without the moments of inertia of a solid body. We see that vector functions of position can be differentiated to give vector velocities and accelerations. We define frames of reference and see how the motion of a particle in a rotating frame can be represented ...
