In this paper, we propose a new formula to accurately estimate the output value on the real machine of the proposed mechanism as a part of the development concerning the high power joint mechanism. The previously proposed formula did not consider the energy loss when the slider translated. Considering the mass of the slider, we derived an expression that can estimate the angular velocity of the output link from the energy conservation law and the geometrical relationship. As a result of comparing the theoretical value and measured value, the performance of real machine could be more accurately estimated by using the proposed mathematical formula.

Underwater imaging is an important part to seafloor observation by underwater robot. Underwater robots provide many images, which contain seafloor environment, and theses images contribute to various fields such as marine biology, marine geology and fishery science. However, underwater images has different properties, such as uneven illumination and light attenuation, compared to images which taken in air, and these properties impede image checking by researchers. In this paper we propose an image enhancement based on scale-gain Retinex, and the proposed method is experimented on the Suruga-bay in Japan.

Rich undersea mineral resources are confirmed around Japan and the research about undersea mineral resources and deep sea creatures has been conducted actively. Since three-dimensional data could not be get by human, three-dimensional measurement technology is important in the deep sea survey. Therefore we designed a measuring device suitable for underwater environment.

A New Tool to Access Deep-Sea Floor "Sampling-AUV" Reviewed International journal

Ishii Kazuo, Sonoda Takashi, Nishida Yuya, Yasukawa Shinsuke, Ura Tamaki, Watanabe Keisuke

Proceedings of International Conference on Artificial Life and Robotics ( ALife Robotics Corporation Ltd. ) 22 300 - 302 2017.01

Language：English Publishing type：Research paper (international conference proceedings)

Underwater robot is one of the important research tools to explore deep-sea. Especially, Autonomous Underwater Vehicles (AUVs) attract attentions as new tools because they are un-tethered and suitable for wide area observation. As the next generation AUV, we have been developing a Sampling-AUV that can dive into deep-sea and bring back marine creatures using a mounted manipulator. In the mission, the AUV transmits the deep-sea floor images to the support ship using acoustic communication, and the operator selects the marine creatures to sample and bring back them. In this talk, we introduce the new AUV, the underwater manipulator and image processing techniques for sampling.

The Proceedings of JSME annual Conference on Robotics and Mechatronics (Robomec) ( The Japan Society of Mechanical Engineers ) 2017 ( 0 ) 2A2-G09 2017.01

Language：Japanese Publishing type：Research paper (other academic)

We developed an image sensing system for an autonomous underwater robot with a benthos sampling function, namely sampling-AUV. The mission of a sampling-AUV consist of following four phases: observation phase (OP), return phase (RP), tracking phase (TP) and sampling phase (SP). For an achievement of the above mission, proposed image sensing system comprises software modules of image acquisition, image enhancement, object detection and image selection, and object tracking. The camera in proposed system acquires an image by intervals of five seconds during OP and RP and of a second during TP. The system completes all processing within image acquisition times by employing high-speed algorithms. We checked operations of proposed system in a pool.
