The proposal of the locomotive system for capsule endoscopes

The capsule endoscope authorized in some countries in late years has the advantage of preparing the observation in difficult small intestines in a past endoscope. However, because the promotion mechanism of a capsule endoscope depends only on the peristaltic motion of a digestive organ, the oversight of change to a morbid state is feared. Authors aim at the achievement of a free movement and remote diagnoses in small intestines, and are developing a locomotive system for capsule endoscopes. This paper describes the proposal of the locomotive system with an electromagnetic actuator, and examination of a simulation model for this locomotive system.
