Edokko MK-1 Project

 

Edokko Mark 1 developped by a consortium of small and medium-sized companies in the Japanese private sector over the course for five years, is an easy-handling free fall deep-sea exploring vehicle which equipped with HD cam and lights covered by a pressure resident glass spherical body. Edokko is manually deployed from the sea surfacec and go down to the seafloor using its own weight. After the completion of exploration with capturing images at the seafloor, Edokko automatically floats back to the surface then. Battery operated Edokko is allowed a continuous deep-sea bounce diving by a battery replacement. Edokko has already deployed and started a deep-see monitoring in various bays and trenches around japan.

Edokko project is orgnized to be an important part and roll of the Strategic Innovation Promotion Program (SIP) launched by the Council for Science, Technology, and Innovation (CSTI), which oversees projects that target scientific and technological innovation in line with Japanese government directions as stated in the Comprehensive Strategy on Science Technology and Innovation and the Japan Revitalization Strategy. This interdisciplinary program among goverment agencies, academic institues and private sectors addresses eleven issues. One of these issues is Next-Generation Technology for Oceasn Resources Exploration.

Sonic Corporation has now become a member of Edokko project as a leader of promotion and advertisement roll to address Edokko in worldwide.

Before a deep-sea exploration in 2013, Edokko was tested at least 8 times in Sagami bay since 2012. The captured images down below show that Hagsidh was acrossing the front of camera at 640m depth.

On November 2013, Edokko was conducted a first dep-sea exploration in Japan trench. Japan trench is one of the deepest sea (8000m depth) so successful exploration at that area for Edokko would scientifically be very meaningful.As a result, the exploration sucsessfully completed without mulfunction and could also record images of many nadal snailfish and Hirondelleagigas which tried to eat a bait at 7800m depth.

Edokko MK-1 Specifications

Eddoko MK-1 is configured to build up four 13-inch diameter glasss spheres equipped with GPS, transponder, LED right and HD video unit inside, are sealed by pressure-resident glass body for each. Originally designed and integated "Rubber communication line" enables a commnication between LED sphere and HD video unit shpere. Transponder* is well helpful to establish a communication or measurement of distance in the sea where we cannot use a radio wave. Transponder also receives a signal and initiates a detachment process to release its weight. GPS unit sends a message of cordinate informaion through ARGOS satellite to operator when it comes back to the surface. GPS sphere and Edokko frame are tied with 20m ropes.

*:Transducer must be equipped.
