This paper summarizes the achievements in fiscal 2000. In the research of a prototype self-propelled system to recognize environment in tubes, the secondary prototype system integrating all of the elemental devices was fabricated, and its functions were verified. In the research of a prototype system to inspect outer surface of fine tube groups, a plurality of single machines that perform movement in narrow spaces on flat surface, interlocking, separation and flaw detection were connected to execute a vertical movement experiment. In the research of a prototype system for works internal to devices, fabrication and functional verification were conducted on the final prototype system which is equipped with functions of measuring very small nicks and performing repair works, which are mounted on the tip of a curved tube unit with multiple degrees of freedom. In the research of a functional device improving technology, a device that puts together artificial muscles, micro-joints, and a suspension device with very low friction was fabricated, and a functional verification was implemented thereon.
