Optimal Design of Components for a Robotic Arm Based on a Matrix Approach of Performance Specifications

Abstract:

Robots are top-level mechatronic systems capable of supporting working tools and performing manipulation tasks. The work shows an optimum method of analysis and design for some components (metallic, plastic) of robots, taking into account a large number of performance specifications and QFD (Quality Function Deploy) , according to imposed or random requirements. A series of data is taken into account: type and characteristics of materials, the shape and size of parts, the manufacturing proces and not the last cost price. Assessments of absolute and relative importance have been carried out to identify the most important specifications. With that idea is proposed a method of selection of the best material, based on the graph theory and the matrix approach for a particular application. The selection factors for the optimum material is described, the relationships of relative importance of factors are found, the factor values (Ri) are normalized, the matrix of selection factors is written. The material with the highest value of the matching index is optimum for the component of the robotic arm. Finally, are analysed whether the performance specifications and quality product match the requirements of the user.
