Abstract
The AUV(Autonomous Underwater Vehicle) for research underwater attracts attention. AUV to perform an experiment of the image processing underwater was developed. This AUV is also used for the investigations into reservoir. The concept of the developed AUV is "can manage with a small number of people" and "low cost". Thruster and a depth sensor were developed to achieve the lower costs. Magnet coupling was used for waterproofing of the thruster. Pneumatic sensor was used for depth sensor. The experimental results, the air pressure sensor can be used as a depth sensor is confirmed.
