LOW COST X-Y CORE POSITIONING SYSTEM USING STEPPER MOTOR

Abstract

X-Y positioning is an important task in industrial applications, as this system is used for welding, cutting or for pick and place applications. The studied X-Y core positioning system is a parallel X-Y position device, which due to less moved masses is potentially capable of fast acceleration and therefore faster positioning than traditional stacked systems. A kinematic model of X-Y core positioning system is derived, which used for accurate position control in X-Y stage of the cart using low cost stepper motor and low cost controller (Arduino Mega2560). The proposed design of X-Y core positioning system which has 8 pulleys and two open ended derive-belts and have the double size of all designs that introduced in this field has its advantages of fast design, simplicity and flexibility. The system is very much simple, rugged, and cost effective. The experimental results show that the proposed system has a high resolution, repeatability and error is within acceptable limit. The proposed strategy used to control positioning in X-Y stage enable accurate cart positioning with max error percentage less than 5%.
