End Effector Position Calculation with the ANN for Tapping Machine

Abstract

Today, manufacturers attach importance to the production of machines that allow for faster production, reduce labor costs, and minimize operation errors in order to provide the increasing demand. The seek for such machines leads manufacturing sector to automation.  In the present study, an automation-supported tapping machine prototype was manufactured. Kinematic equations were used for determining the location of the end effector in Cartesian space, whereas inverse kinematic equations were used for angular positions in joint space relative to positions in Cartesian space. Based on the results of the kinematic equations, the data obtained in certain positions were taught to the system through ANN.

The position values for the angles known through the artificial intelligence algorithm have been taught to the system. Then the position coordinates to be reached by this manipulator, which has four degrees of freedom, for the intermediate position coordinate values through artificial neural networks (ANN) have been obtained. It is expected that the device controlled by artificial intelligence will not be affected by the variables in parameter or force changes requiring high working performance. With the control of the positions through ANN, it has been ensured that the position control of the tapping robot manipulator is predicted based on artificial intelligence techniques depending on the angle values of the limbs, and the robot is prevented from going to a position that is on a different trajectory. Accordingly, the robot arm has been made controllable with ANN techniques. With ANN modelling, the position of the end point to perform the tapping process was estimated with high reliability. To light the way for future research, a rough simulation was made to see whether the end point would go to a different position in space
