Abstract
In recent years, the pathology in the colon grows up annually since people of all ages prefer to have less fiber and more fat food. Therefore, the colonoscopy is generalized in developed countries. But it requires much time to acquire a dexterous skill to perform an operation and the procedure is painful to the patient. Therefore, some studies on the development of autonomous colonoscope are carried out. In this paper, we propose a new and simple locomotive mechanism that can be propelled by elliptic motion of a leg. It has several legs that have constant phase difference each other and those legs are disposed along the upper and lower of the body. In order to evaluate the performance of locomotive mechanism, we carried out the simulations of moving characteristics and the experiments in the colon of a dead pig.
