Design of geometric-based inverse kinematics for a low cost robotic arm

Abstract

In order to effectively control end effector of a robotic manipulator, one needs to solve inverse kinematics of the robot. This paper reports an investigation to solve inverse kinematics of a low cost 6 degrees of freedom (6 DOF) robotic arm. Since this robot provide no feedback signal, we propose to use a simple geometric-based inverse kinematics. Experimental results show the effectiveness of the proposed method, while the accuracy is still acceptable to some extent.
