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.
LT: Laser Tracker TCP: Tool center point R1: Reflector 1 TM: T-Mac S: Spindle W: Work-piece To calculate the control errors [[PHI].sub.e] of the robot axis angles, the target axis angles [[PHI].sub.t] and the actual axis angles [[PHI].sub.a] have to be calculated first using the inverse kinematics
. Let "[mathematical expression not reproducible]" denote the 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.
Among their topics are the model reference adaptive control of robotic manipulators, the output feedback adaptive control of uncertain dynamical systems with event-triggering, the adaptive control of modular ankle exoskeletons in neurologically disabled populations, the unification of bipedal robotic walking using a quadratic program-based control Lyapunov function: applications to the regulation of zero moment point and angular momentum, and an evaluation of micro-genetic and micro-immune algorithms for solving inverse kinematics

Solving the inverse kinematics

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.
