Robotic Automation of Mechanical Verification

Abstract: This master thesis explores the implementation of Collaborative robots into Elekta's mechanical product verification process. Elekta is a pioneer in precision radiation therapy solutions. Ensuring the compliance of Elekta's products with performance, safety, and quality criteria is of great importance. The existing verification process faces challenges regarding resource management, ergonomics, efficiency, and test accuracy.This thesis delves into three main research areas, the study begins with theoretical research investigating Industry 4.0, automation, and human-robot collaboration, focusing on the ABB GoFa Cobot. The following research area analyzes the existing market, regarding the exploration of different robotic grippers. Lastly, the third research area focuses on the user. Including interviews and observations with Elekta testing employees and industry experts from ABB and Atlas Copco.This thesis examines insights from theoretical, market, and user research to identify key factors influencing the development of concepts, prototypes, and models. By this, strengths, weaknesses,and a criteria value matrix were created for various gripper options for Elekta's tests. Furthermore, test parameters were defined to make the test suitable for automated Cobot verification. Lastly, the conclusion from the user research was examined in several parts, including, efficiency, safety, ergonomics, limitations, robotics, and industry. The thesis continued with a creative process that contains the development and iterations of concepts by CAD modeling, 3D printing, and Cobot programming for a specific verification test. The results of this thesis include Cobot implementation guidelines, covering the selection of suitable tests for automation, gripper selection, and finger development. The report then delves into the sustainable regards related to Cobot implementation, studying social, economic, and environmental sustainability. Furthermore, decisive factors that could influence the project were discussed. In conclusion, this master's thesis successfully addresses Elekta's mechanical product verification challenges through the strategic implementation of Cobots. It is expected to increase efficiency, reduce ergonomic risks, improve resource management, and increase test precision. This research provides a blueprint for Cobot implementation at Elekta and positions the company at the forefront of modern industrial technology, emphasizing the potential for further development in this field.
