Abstract

This paper introduces an optimization technique based on the particle swarm optimization algorithm (PSO) for solving the inverse kinematics problem for an n-DOF manipulator. The proposed algorithm trying iteratively to find the best set of angles that locus the manipulator at the desired position and orientation. Each iteration, a set of angles are assigned to the joints and derived to calculate the position and orientation of the end-effector using Denavit-Hartenberg (DH) method and Euler angles equations. Then obtaining the error between the current position/orientation (P_c/O_c) of the end-effector with the desired position/orientation (P_d/O_d). A 6-DOF manipulator has been used as an example in our simulation. Obtained results show that PSO can be efficiently used for inverse kinematics solution.
