QYSEA&KDDI:世界で初めて「水空一体無人機」が登場し、QYSEAとKDDIが共同開発します QYSEA&KDDI:世界で初めて「水空一体無人機」が登場し、QYSEAとKDDIが共同開発します

In recent weeks, Japanese telecommunications operator KDDI, commercial drone manufacturer PRODRONE, and underwater robotics firm QYSEA unveiled the world’s first ‘Sea-Air Integrated Drone’ during a flight showcase at the Hakkeijima Sea Paradise in Yokohama. The revolutionary drone aims to modernize offshore and marine operations with its intelligent capabilities, high working efficiency, and minimized manpower required.

A Joint Collaboration & Breakthrough in Drone Technologies

The world's first sea-to-air drone is jointly manufactured by telecommunications operator KDDI and underwater robotics manufacturer QYSEA Technology, featuring the combination of a heavy-duty aerial drone and QYSEA’s industrial-class FIFISH PRO V6 PLUS ROV. This ambitious project had been set out by KDDI six years earlier, who had sought to combine advanced mobile communication networks with drone technologies that would deliver extended flying distances and lengths.

Seamless Operation from Land, Air & Sea

The technological achievement between KDDI and QYSEA has resulted in the first commercial drone capable of operating seamlessly through land, sea, and air. Through long-range mobile communications, the drone is operated remotely to fly to its preset route at sea. After landing at its designated location, the FIFISH ROV is released and deployed to work.

The pilot is then able to remotely operate with the ROV from a safe working location, and perform a variety of inspection, maintenance, and repair work underwater.

Elevating Upon Traditional Methods

Traditional and widely-used methods in underwater inspections often involve challenges with time, energy, monetary costs, and human risks, where workers would need to use boats to drive out to offshore platforms and make multiple dives for their inspections.

The KDDI and QYSEA jointly-developed ‘Sea-Air Integrated Drone’ provides a breakthrough within remote marine-based operational work. Without the need to leave their onshore working location, the operator can deliver inspections with real-time visual feedback and operate through underwater environments with a variety of sampling, measurement, and manipulation tools, as well as be able to live-stream operations for multi-person collaborations.

Essential Marine-Based Applications

The ‘Sea-Air Integrated Drone’ has shown it will have far-reaching applications across the various marine-based industries. In offshore wind power, the drone can be deployed to perform complex inspections and maintenance work on its frames and foundations to greatly reduce human risks. In the world of aquaculture, the drone is able to fly out to monitor its livestock and crops, as well as perform maintenance and repair work through the ROV’s multitude of add-on tools. Other marine-based applications include operations involving search and recovery, hull inspections, and various other subsea infrastructures.

With further details of its release coming in early 2022, the ‘Sea-Air Integrated Drone’ will undoubtedly lead an essential path towards the development of a sustainable ocean economy and the global goal of carbon neutrality.

Additional Vehicle Integrations with the FIFISH

In China’s Shandong province, QYSEA has recently teamed up with local technology scientists to debut the nation’s first unmanned drone and ship for mariculture operations. Utilizing remote communication technologies, aquaculture farmers and scientists can sail out to farms to monitor livestock and crops from a safe onshore location.

Through the technological collaboration of ocean robotics and artificial intelligence, the unmanned sea vehicle delivers seamless surface-to-underwater control, ultra-clear and real-time imaging feedback, as well as remote autonomous operational capability. With fewer required costs, manpower, and energy, the emergence of compact unmanned ROVs is a great breakthrough in efficiency and sustainability, compared to the traditional methods used in mariculture operations.
