Inverse Kinematics (IK) Solution of a Robotic Manipulator using PYTHON

Abstract

Present global engineering professionals feels that, robotics is a somewhat young field with extremely ruthless target, the crucial one being the making of machinery/equipment that can perform and feel like human beings. Robot kinematics deals with the study of motion of linkages which includes displacement, velocities and accelerations of a robot manipulator analytically. Deriving the proper kinematic models for an open chain mechanism of a robot is essential for analyzing the performance of industrial robotic manipulators. In this study, first scrutinize a popular class of two and three degrees of freedom open chain mechanism whose inverse kinematics admits a closed-form analytic solution. A simple coding was developed in python in an easy way. In this connection a two link planer manipulator was considered to get inverse kinematic solution developed in python environment. For this task, we present a solution for obtaining the joint variables of linkages to reach the position in a work space with the corresponding input values such as link lengths and position of end effector.
