Abstract

Programmable Logic Controller (PLC) is making big role in the field of automation and robotics. This paper described the design and implementation of Programmable Logic Controller (PLC) based robot manipulator control using two different artificial intelligence algorithms - Position Based and Imaged Based algorithm. The controlled robot is 5 degrees of freedom (DOF) manipulator with a closed kinematic chain, designed for high-performance pick and place applications. The control software is fully developed on a commercial PLC system, using its standard programming tools and the multi-tasking features of its operating system. In particular, this paper analyze in detail the drawbacks and the advantages related to the choice of standard PLCs in this kind of applications, compared to the much common choice of specialized hardware or industrial personal computers, with particular emphasis on the computational performances obtained with the proposed control architecture.
