EEZ and Hydrothermal plumes

Improvement in efficiency is required → Low cost exploration

If you use just one AUV for exploring in Japan’s EEZ, You need about 900 years!!

Multiple AUV operation

The step toward Multiple AUV operation

For Safe and Secure operation of robot,Communication network between robot and man is necessary
