Design and construction of a 3 degrees of freedon robot arm using collaborative concept

Abstract

It is estimated that the market growth of manipulator robot arms for industrial applications will enter in a significant growth cycle in the next years. However, there are peculiarities in this growth, which is conditioned to the participation of small and medium enterprises as a consuming source of this type of technology. The consumer market, once dominated by large corporations, is now also manifesting itself in small industry centers. Based on this trend, it is proposed the design and construction of an electromechanical mechanism closer to a robot arm concept. The research group on Mechatronics at UFSCar / CNPq, have been developing studies related to the positioning accuracy of robotic joints and the selection of the best concept of robotic manipulator, generating the basis for the development of a functional robotic prototype, with collaborative characteristics, three degrees of freedom and closed loop using potentiometer, Arduino type controller and electronic motor control interface. The project reviews conceptual design and fabrication in robotics. Tests will be at the last part, pointing to potential issues to be eliminate, and also future versions. (AU)
