  • Development of Peristaltic Crawling Robot Using Magnetic Fluid

抄録

Using a magnetic fluid, the earthworm-type robot was developed for running the peristaltic movement. In this earthworm-type robot, a cell equivalent to a segment of the earthworm is composed of a natural rubber tube into which a water-based magnetic fluid is sealed up. The cells are connected with rod-like elastic bodies of natural rubber. It was confirmed that this robot can travel in an acrylic tube (inner diameter : 12mm, outer diameter : 14mm) by providing a shifting magnetic field from the exterior. This article will describe the pattern of the peristaltic movement of an earthworm, how our earthworm-type robot moves, the mechanism of its movement.
