Abstract - We have developed a multi-legged underwater robot, CR200. This robot is supposed to inspect and work in high tidal current environment with low visibility. CR200 is equipped with a high-resolution acoustic underwater camera to clear her visibility in highly turbid water where any optic cameras are useless. In this paper, we introduce the acoustic camera and its preliminary operation in water tank. We compared images between the acoustic camera and a multi-beam sonar. Underwater experiments was conducted to acquire acoustic images. The acousic images are compared with images taken by a typical optical camera. Measuring size of a target object on the acoustic images and simple mosaic work are also included.
