A solution method for inverse kinematics of automated fiber placement (AFP) trajectory is proposed. The D-H method is used to establish the kinematical model of the AFP head, based on this kinematical model, the mathematical model of the forward solution of the AFP trajectory is constructed; ...
Kinematics is the study of motion without considering the cause of the motion, such as forces and torques. Inverse kinematics is the use of kinematic equations to determine the motion of a robot to reach a desired position. For example, to perform automated bin picking, a robotic arm used in...
In general, the set of solutions to the inverse kinematics problem for a redundant manipulator consists generically of a finite number of nontrivial self-motion manifolds (the solution branches) in the configuration space. Any point in this set solves the task of positioning and orienting the end...
The goal of the inverse kinematics problem for robotic arms is to determine the angle of each joint given the position and posture of the end effector. The traditional inverse kinematics solution methods of manipulators mainly include algebraic methods4, geometric methods5 and numerical methods6. Alg...

The proposed HBBO algorithm has been used to solve the inverse kinematics problem of the 8-DOF redundant humanoid manipulator. Numerical simulation results demonstrate the effectiveness of this method.doi:10.1631/FITEE.14a0335Z. RenZhenhua Wang
Therefore, there is almost no research on the inverse kinematics solution method for redundant sliding manipulators. Although the numerical method above based on the differential is very versatile, it is necessary to calculate the inverse of the Jacobian matrix in real time, which increases the ...

If either algorithm converges to a configuration where the cost is close to zero within a specified tolerance, it has found a solution to the inverse kinematics problem. However, for some combinations of initial guesses and desired end effector poses, the algorithm may exit without finding an ...
