Mechatronics and automation technology has led to technological change and innovation in all engineering fields, affecting various disciplines, including machine technology, electronics, and computing. It plays a vital role in improving production efficiency, reducing energy consumption and improving product quality and safety, and will be central to the further advancement of technology and industry, bringing convenience and innovation to even more areas. This book presents the proceedings of ICMAT 2023, the 2nd International Conference on Mechatronics and Automation Technology, held as a virtual event on 27 October 2023. The aim of the conference was to provide a platform for scientists, scholars, engineers and researchers from universities and scientific institutes around the world to share the latest research achievements in mechatronics and automation technology, explore key challenges and research directions, and promote the development and application of theory and technology in this field. A total of 121 submissions were received for the conference, of which 77 were ultimately accepted after a rigorous peer-review process. The papers cover a wide range of topics falling within the scope of mechatronics and automation technology, including smart manufacturing; digital manufacturing; additive manufacturing; robotics; sensors; control; electronic and electrical engineering; intelligent systems; and automation technology, as well as other related fields. Providing an overview of recent developments in mechatronics and automation technology, the book will be of interest to all those working in the field.
