Abstract: An AUV includes: an underwater vehicle main body configured to sail along an inspection object located in water or on the bottom of the water; an arm extending from the underwater vehicle main body; an inspection tool portion including a contact portion configured to contact the inspection object and an inspection device configured to inspect the inspection object; and a passive joint provided between the arm and the inspection tool portion and configured to allow passive rotation of the inspection tool portion relative to the arm about at least one axis.

Abstract: A submersible vessel includes: a hull; a propulsor that propels the hull; a front sensor that sequentially detects locations of an inspection target in front of the hull; a controller that controls the propulsor such that the hull passes through above the detected locations; a movable arm attached to an arm reference point of the hull; an inspection tool at the movable arm that inspects the inspection target; and a position detector that acquires positional information including a position, attitude, or speed of the hull. Based on the information from the position detector, the controller estimates a pass-through position of the arm reference point after a predetermined time. The controller controls the movable arm such that before the time elapses, a positional relation between the arm reference point and inspection tool becomes a positional relation between the estimated pass-through position and a target point on or above each location.

Abstract: An object of the present invention is to provide a bone regeneration material suitable for bone (in particular, alveolar bone) regeneration. The present invention provides a non-woven fabric containing a bone prosthetic material wherein the bone prosthetic material is included between biocompatible fibers that constitute the non-woven fabric. The non-woven fabric may be suitably used as a bone regeneration material (in particular, a dental bone regeneration material).
