Stellar kinematics is the study of the movement of star s without needing to understand how they acquired their motion. This differs from stellar dynamics , which takes into account gravity gravitational effects . The motion of a star relative to the Sun can provide useful information about the origin and age of a star, as well as the structure and evolution of the surrounding galaxy . In astronomy , it is widely accepted that most stars are born within molecular clouds known as molecular cloud stellar nurseries . The stars formed within such a cloud compose open clusters containing dozens to thousands of members. These clusters dissociate with time. Stars that separate themselves from the cluster s core are designated as members of the cluster s stellar association . If the remnant later drifts through the galaxy as a coherent assemblage, then it is termed a moving group . Space velocity The component of stellar motion toward or away from the Sun, known as radial velocity , can be measured from the spectrum shift caused by the Doppler effect . The transverse, or proper motion must be found by taking a series of positional determinations against more distant objects. Once the distance to a star is determined through astrometric means such as parallax , the space velocity can be computed. ref name atoe05 cite web date 2005 08 18 title Stellar Motions Extension url http outreach.atnf.csiro.au ...

Forward kinematic animation is a method in 3D computer graphics for animating models. The essential concept of forward kinematics forward kinematic animation is that the positions of particular parts of the model at a specified time are calculated from the position and orientation of the object, together with any information on the joints of an articulated model. So for example if the object to be animated is an arm with the shoulder remaining at a fixed location, the location of the tip of the thumb would be calculated from the angles of the shoulder , Elbow joint elbow , wrist , thumb and knuckle joints. Three of these joints the shoulder, wrist and the base of the thumb have more than one degrees of freedom engineering degree of freedom , all of which must be taken into account. If the model were an entire human figure, then the location of the shoulder would also have to be calculated from other properties of the model. forward kinematics Forward kinematic animation can be distinguished from inverse kinematic animation by this means of calculation in inverse kinematics the orientation of articulated parts is calculated from the desired position of certain points on the model. It is also distinguished from other animation systems by the fact that the motion of the model is defined directly by the animator no account is taken of any physical law s that might be in effect on the model, such as gravity or collision with other models.

Citations missing article date November 2009 Stellar drift , or the motion of stars, is a necessary result of the Special relativity Lack of an absolute reference frame lack of an absolute reference frame in special relativity. The term is used mainly in science fiction, however in particular, the phenomenon affects stargate device stargates in the Stargate franchise. Nothing in space stands still more precisely, standing still is meaningless without defining what still means. Most galaxy galaxies have been moving away ever since the Big Bang , as explained by the metric expansion of space . Galaxy motion is also influenced by galaxy groups and clusters . Stars orbit moving galaxies, and they also orbit moving star cluster s and binary star companion star s. Planets orbit their moving stars. Stellar drift is measured by two components proper motion multiplied by distance and radial velocity . Proper motion is a star s motion across the sky, slowly changing the shapes of constellation s over thousands of years. It can be measured using a telescope to detect small movements over long periods of time. Radial velocity is how fast a star approaches or recedes from us. It is measured using redshift . Both components are complicated by the Earth s orbit around the Sun, so the motions of stars are described relative to the Sun, not the Earth Star Kinematics kinematics of stars .

321 kinematic structure is a design method for robot ic arms serial manipulator s , invented by Donald L. Pieper and used in most commercially produced robotic arms. The inverse kinematics of serial manipulators with six revolute joint s, and with three consecutive joints intersecting, can be solved in Closed form expression closed form , i.e. a set of equations can be written that give the joint positions required to place the end of the arm in a particular position and orientation. ref D. L. Pieper. The kinematics of manipulators under computer control. PhD thesis, Stanford University, Department of Mechanical Engineering, 1968. ref An arm design that does not follow these design rules typically requires an iterative algorithm to solve the inverse kinematics problem. The 321 design is an example of a 6R wrist partitioned manipulator the three wrist joints intersect, the two shoulder and elbow joints are parallel, the first joint intersects the first shoulder joint orthogonal ly at a right angle . Many other industrial robots, such as the Programmable Universal Machine for Assembly PUMA , have a kinematic structure that deviates a little bit from the 321 structure. The offsets move the singular positions of the robot away from places in the workspace where they are likely to cause problems.

Gerard of Brussels lang fr G rard de Bruxelles , lang la Gerardus Bruxellensis was an early thirteenth century geometer and Medieval philosopher philosopher known primarily for his Latin book Liber de motu or On Motion , which was a pioneering study in kinematics , probably written between 1187 and 1260. It has been described as the first Latin treatise that was to take the fundamental approach to kinematics that was to characterize modern kinematics. ref Marshall Clagett, The Reduction of Curvilnear Velocities to Uniform Rectilinear Velocities, A Source Book in Medieval Science , ed. Edward Grant Harvard University Press, 1974 , 234. ref He brought the works of Euclid and Archimedes back into popularity and was a direct influence on the Oxford Calculators four kinematicists of Merton College in the next century.

M. McCarthy and G. S. Soh, Geometric Design of Linkages, 2nd Edition, Springer 2010 ref An example is the Klann linkage used to drive the legs of a walking machine. In general, each joint of a linkage connects two links, and a binary link supports two joints. If we consider a hexagon to be constructed from six binary links with six of the seven joints forming its vertices, then, the seventh joint can be added to connect two sides of the hexagon to forming a six bar linkage with two ternary joints. This type of six bar linkage is said to have the Watt topology. A six bar linkage can also be constructed by first assembling five binary links into a pentagon, which uses five of the seven joints, and then completing the linkage by adding a binary link that connects two sides of the pentagon. This again creates two ternary links that are now separated by one or more binary links. This type of six bar linkage is said to have the Stephenson topology.

unreferenced date April 2009 Joint constraints are rotational constraints on the joint s of an artificial bone system. They are used in an inverse kinematics chain, for such things as 3D animation or robotics . Joint constraints can be implemented in a number of ways, but the most common method is to limit rotation about the X, Y and Z Axis of rotation axis independently. An elbow, for instance, could be represented by limiting rotation on Y and Z axis to 0 degrees, and constraining the X axis rotation to 130 degrees. To simulate joint constraints more accurately, dot products can be used with an independent Wiktionary axis axis to repulse the child bones orientation from the unreachable axis. Limiting the orientation of the child bone to a border of Vector geometric vectors tangent to the surface of the joint, repulsing the child bone away from the border, can also be useful in the precise restriction of shoulder movement.

In applied mathematics as used in the engineering field of robotics , an arm solution is a solution of equations that allow the calculation of the precise design parameters of a robot s arms in such a way as to enable it to make certain movements. A typical industrial robot is built with fixed length segments that are connected either at joints whose angle s can be controlled, or along linear slides whose length can be controlled. If each angle and slide distance is known, the position and orientation of the end of the robot arm relative to the base can be computed with the simple trigonometry in robot control . Going the other way &mdash calculating the angles and slides needed to achieve a desired position and orientation &mdash is much harder. The mathematical procedure for doing this is called an arm solution . For some robot designs, such as the Stanford arm , SCARA robot or cartesian coordinate robot s, this can be done in Closed form expression closed form . Other robot designs require an iterative method iterative solution.
