In a world suffering from an ageing population and declining birth rate, service robotics and mechatronics have an increasingly vital role to play in maintaining a safe and sustainable environment for everyone. Mechatronics can be used in the reconstruction or restoration of various environments which we rely upon to survive; for example the reconstruction of a city after an earthquake, or the restoration of polluted watersThis collection of papers was originally presented at the 7th International Conference on Machine Automation, 2008, in Awaji, Japan, and covers a variety of new trends in service robotics and mechatronics.Service Robotics and Mechatronics showcases the latest research in the area to provide researchers and scientists with an up-to-date source of knowledge and basis for further study, as well as offering graduate students valuable reference material.
