According to an embodiment, an in-pipe work device is inserted into a pipe and remotely controlled by a control device to perform an operation for an inner surface of the pipe. The in-pipe work device has: a main unit; a main-unit support unit; a rotation arm; a process head; a first distance sensor; and a process head position adjustment mechanism that changes a distance from a rotation center of the rotation arm to the process head. The control device makes the process head position adjustment mechanism expand and contract based upon a result of measurement by the first distance sensor and operation condition information that is input in advance. |
