Preface: 7th International Conference on Automatic Control and Mechatronic Engineering (ACME 2025)

2025 7th International Conference on Automatic Control and Mechatronic Engineering (ACME 2025) is to facilitate an exchange of information on best practices for advanced automation, control technology, vehicle engineering, electronic engineering, electrical engineering, mechanical engineering, and mechatronic engineering, addressing the problems and opportunities of a sustainable future. This conference provides a forum for engineers and scientists in academia, industry, and government to address the most innovative research and development including technical challenges and economic issues, and to present and discuss their ideas, results, work in progress and experience in these aspects. ACME 2025 was held during June 28-29, 2025, in Sapporo, Japan. The development of science occurs by utilizing collaboration with other branches of science such as technology, mechanical engineering, and mathematics. The distinctive feature of collaboration that has become an important value. We thank all participants for ACME 2025 who have contributed their research. I hope, with this kind of collaboration, we can jointly improve the development quality in this era.
