Abstract
An in-pipe robot is provided with a rotary actuatorthat rotates the drilling bladein the circumferential direction of an existing pipe. A wheel bodyprovided with a traveling wheelon both sides and a wheel bodyprovided with a traveling wheelon both sides are supported between side framesof a chassis via pinsandThe other ends of both the wheel bodies are rotatably coupled around an axleof an intermediate wheelas a pivot. When both the wheel bodies rotate, the intermediate wheels and the rotary actuator move above a horizontal line passing through the pin center. Each pin is disposed at the midpoint of a line connecting the center of the traveling wheel and the center of the intermediate wheel so that the rotation axis vof the rotary actuator coincides with the pipe center axis of the existing pipe.
