  • OS1212 Fabrication of an Inspection Robot using Pneumatic Soft Actuators for the Large Intestine

抄録

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. Many microrobots that can move in the large intestine have been proposed by several research groups. The actual large intestine in our human body is flexible and has very severe bending curve at the sigmoid. We propose a new microrobot that can surely move in the large intestine in the human body. We use six rubber bellows in series. Two outer rubber bellows actuators are provided eight bulging rubber sheets. These are called as the braking mechanism. The moving mechanism moves the microrobot by stretching and shrinking. Three rubber bellows are arranged after the braking mechanism in a triangle condition. The microrobot has been confirmed to move from the anus to the cecum in the artificial human's large intestine model for the freshman doctor's inspection training using the fiberscope.
