Performance Analysis of SCORBOT ER 4u Robot Arm

Abstract

Adaptive programming and flexible planning are the key features of the Robotisation which is gaining a popularity in the Industrial sector. Most important parameter in the case of optimization of error in robotized processes are testing and trials. It influences the working of robot and demands to perform effectively at variable kinetic conditions inside the work volume. The total focus of presented work is to calibrate the operating parameters of manipulator arm at various conditions. SCORBOT-ER 4u is robust, easy to use and effective, which is used widely in manufacturing engineering fields. In this paper, performance analysis of robot arm mainly focuses on the performance improvisation of a robot by using methods of reconditioning, and programming. A robot performance can be measured by the parameters such as, accuracy, repeatability, resolution, workvolume, operational speed, positional error, etc. SCORBOT ER 4u is operated for three different parameters viz speed, load and distance. Robot arm is operated with RoboCell software by giving different program and the repeatability is checked by taking points on polar plot by varying speed and load. And this difference in point is checked by digital microscope. 
