20702 Fabrication of a new Brake Mechanism for an In-Pipe Mobile Microrobot

An inspection of the large intestine is very effective in order to prevent the large intestine cancer. A fiberscope is excellent for the inspection of the large intestine. However, the inspection by the fiberscope often attends many pains and injuring of the intestine. We are hoping the inspecting method for the intestine with no pain and no injuring of the intestine before the operation by the fiberscope. Now, we propose a new microrobot that can surely move in the large intestine in the human body. We need a holding work to the radius direction of the flexible large intestine and a driving work to longitudinal direction of the large intestine.
