Underwater and maritime robot facilities

This is the only test site in Japan for the demonstration test by robot, regarding underwater infrastructure inspection and disaster response.These facilities can reproduce conditions occurring in the water such as dams, rivers, submerged urban areas, or harbors.

1Submerged urban field

This field can reproduce conditions of submerged city with flood damage. It can be used for information gathering, search/rescue training and etc. by water- surface and underwater robot and unmanned aerial vehicles. It can also be used for testing under conditions where objects and obstacles are sunk, rescue training with manned helicopters or boats.

2Indoor water tank

This facility reproduces conditions of dams, rivers, and harbors to perform tests and maneuver training on inspection and investigation with the underwater/ water-surface robot. The large water tank is equipped with a test piece simulated an aging underwater structure, and enables installation of inspection objects, generating water flow, reproducing the dark places. In a small water tank, the performance on observation instruments to be installed can be tested by controlling the turbidity.
