Development of a peristaltic crawling robot using magnetic fluid on the basis of the locomotion mechanism of the earthworm

摘要

In the field of bio-engineering the aim of developing new machines which utilize the motion and control of organisms as a model is attracting attention. This technology is pursued by paying attention to various shapes and movements of organisms and autonomous system of organisms that act in response to the environment surrounding them, and by mechanically elucidating the locomotion mechanism, propulsive mechanism, nerve system and sensation system for these organisms. On the other hand, in the field of hydrodynamics, magnetic fluid that changes its apparent viscosity depending on the magnetic field has been developed, and its utilization is under trial in various fields.
