Focused sections have played an important role in bringing together solutions from research and engineering for a specific area in mechatronics, which is becoming increasingly important and has a board range of applications. Focused Section provides an opportunity to cover recent progress, and publishes original, significant and visionary papers describing scientific methods and technologies, which may be abstractions, algorithms, theories, methodologies, and case studies in the specific focused area. The aim is to make available to a large audience the state-of-the-art results on some critical research issues in this area.
