The forward kinematic equations can be used as a method in 3D computer graphics for animating models. The essential concept of 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 ...
From this point of view the kinematics equations can be used in two different ways. The first called forward kinematics uses specified values for the joint parameters to compute the end-effector position and orientation. The second called inverse kinematics uses the position and orientation of the end-effector to compute the joint parameters ...
A fundamental tool in robot kinematics is the kinematics equations of the kinematic chains that form the robot. These non-linear equations are used to map the joint parameters to the configuration of the robot system. Kinematics equations are also used in biomechanics of the skeleton and computer animation of articulated characters.
Robotics engineers use forward kinematics to calculate the positions and orientations of a robot's end-effector, given specific joint angles, and inverse kinematics to determine the joint movements necessary for a desired end-effector position. These calculations allow for precise control over tasks such as object manipulation or locomotion.
This provides a direct relationship between actuator positions and the configuration of the manipulator defined by its forward and inverse kinematics. Robot arms are described by their degrees of freedom. This is a practical metric, in contrast to the abstract definition of degrees of freedom which measures the aggregate positioning capability ...
The system of six joint axes S i and five common normal lines A i,i+1 form the kinematic skeleton of the typical six degree-of-freedom serial robot. Denavit and Hartenberg introduced the convention that z-coordinate axes are assigned to the joint axes S i and x-coordinate axes are assigned to the common normals A i , i +1 .
Continuum mechanics – the branch of mechanics that deals with the analysis of the kinematics and the mechanical behavior of materials modeled as a continuous mass rather than as discrete particles. Dynamics – the study of the causes of motion and changes in motion; Fluid mechanics – the study of fluids and the forces on them.
The term kinematic is the English version of A.M. Ampère's cinématique, [9] which he constructed from the Greek κίνημα kinema ("movement, motion"), itself derived from κινεῖν kinein ("to move"). [10] [11] Kinematic and cinématique are related to the French word cinéma, but neither are directly derived from it.
