Conceptual Design Framework for Developing a Cylindrical Robot Manipulator for Material Handling in Zimbabwean Small to Medium Enterprises: A Finite Element Approach

Abstract

In many small to medium engineering companies in Zimbabwe the need for material handling devices has become a necessity. There is lack of machinery that could increase production rate, improve product quality and reduce manufacturing costs while maintaining safe working environments. Material handling is a bottle neck during production due to lack of proper equipment and plant layout thus this research seeks to improve the material handling system through the conceptual design of a framework for the application of a cylindrical robot. There are many robots in the market that will improve material handling effectively. The purpose of this paper is to present a framework that has a structured approach for developing cylindrical robots based on finite element analysis methods that will be used by small and medium engineering enterprises (SMEs).This will enable the SMEs in developing nations to maintain competitive prices on products with minimal work accidents. The research explores the current literature and design approaches used to develop cylindrical robots. The paper also provides detailed methodologies to be used for structural analysis, component simulation and performance evaluation of the machine through finite element analysis (FEA). The framework provides suitable guidelines for designers to make appropriate decisions from the initial design stage to the commercialization of the design. The authors conclude that the preliminary framework be applied to formalize design steps for sim ilar material handling machinery implementation in the SME sector.
