inverse kinematics

In 3D animation, a technique that provides automatic movement of objects. It allows elements of an object to be linked, such as the parts of an arm or leg, and causes them to move in a prescribed, realistic manner.

Inverse kinematics exemplifies the analysis of a constrained system of rigid bodies, or a kinematic chain, such that a robot's kinematic equations can be used to define loop equations for a complex articulated system, which are nonlinear constraints on the configuration parameters of the system.

Let "[mathematical expression not reproducible]" denote the inverse kinematics function:
Inverse Kinematics model of the Hexapod is essential to deduct the required angle for each joint in the robot.
The kinematics method is divided into forward kinematics and inverse kinematics.
According to (2)-(3), the system inverse kinematics equations can be defined as
Thus, the joint space position points corresponding to the discrete operative space (Cartesian space) can be obtained according to inverse kinematics; subsequently, the joint trajectory of the robot can also be obtained via the polynomial or the cubic splines method by connecting the relevant position points.

An Engineering Technology teacher could conduct demonstrations of the applications of topics like inverse kinematics or the results of a manipulator's dynamics to mechanical engineering robotics students, but that same teacher may or may not be able to teach the theory of those topics to the students.
Similarly, in robotics, Inverse Kinematics algorithm is a mathematical tool to compute movement of a robotic structure.
The full-body controller is implemented for the Atlas robot using quadratic programming to perform inverse dynamics and inverse kinematics. For each task, desired Cartesian motions for specific locations on the robot (e.g., foot, hand, and CoM) in the high-level controller are specified.
