As part of the Next-Generation Technology for Ocean Resources Exploration project in the Cross-ministerial Strategic Innovation Promotion Program (SIP) of the Japanese government, Japan Agency for Marine-Earth Science and Technology (JAMSTEC) is promoting the development of the cabled seafloor observatory system which allows long-term monitoring of hydrothermal vents and ecological changes. Exploring...
Utilizing a variety of substances which exist in seafloor as resources has a possibility to influence on the environment. The practical use of seafloor resources needs a development of environmental impact prediction method and a development of framework to carry out the continuous environmental impact assessment. A submarine cabled observatory is plant to deploy to hydrothermal activity area in submarine...
To efficiently evacuate an area threatened by volcanic disaster, onsite observation of active volcanoes by remotely controlled mobile robot systems is desired. Issues involved with developing such systems include planning a safe path for the robots. In this research, our objective was to realize a safe path planning method based on a digital elevation map (DEM) of volcanic mountain fields that considers...
Recently, there has been rapid progress in the development of nondestructive sensing method for underground structures using artificial earthquake and seismometer array technology. However, this requires the deployment of many sensing devices over a wide area on a target outdoor field; such work is currently conducted in manually. To automate such work, our research group has been developing an autonomous...
