| Research Abstract |
We proposed to use the helical rotation mechanism as a propulsion device of the endoscope, and developed some prototypes of smaller sizes as the endoscope. A helical rotation is a motion in which a helical body revolves about its body axis. The advantages of a helical rotation mechanism is it can be actuated by a simple, small and soft mechanism, it has low friction against the inside wall of the tube, it has hermetical body, and it does not disturbs fluid flowing in the pipe. We developed prototypes actuated by wire, SMA (shape memory alloy), and air pressure, and confirmed their specifications.
