■Exhibition Concept
"Sea Japan" is the largest exhibition in Eastern Japan, held once every two years, where domestic and international maritime stakeholders gather.
We will exhibit products that respond to the increasingly serious shortage of personnel in recent years and the international increase in demand for underwater surveys in ships and ports.
The exhibition will include the FF series of underwater drones and the underwater drone simulator FF Virtual. The biggest highlight this time is the new domestic underwater drone "FF2," which will soon be available for sale. In addition to the evolution of the aircraft hardware, a survey support system based on positional space is also a feature.
Domestic Underwater Drone FF2
A high-spec model that further develops the FF1's development concept and improves performance.
Both the aircraft and software were newly designed, and development proceeded while repeatedly conducting actual machine verification in-house. Through repeated verification and improvement, we have pursued the optimal aircraft for surveys in terms of both hardware and software.
Industrial Underwater Drone FF1
An underwater drone that can be carried by one person, inheriting a globally proven aircraft design, while also featuring FINDi's unique payload area on the top. It is a versatile machine that can also be used for upward surveys of water surfaces, structures, and the flat bottoms of hulls.
It is designed to be deployed from manholes with a diameter of 600mm installed in facilities, etc.
Underwater Navigation System
This is an in-house developed underwater navigation system for confined spaces, installed in the FF2.
This system visualizes the movement trajectory acquired by the acoustic sensor installed in the FF2 in real time. Furthermore, by importing any drawing, the current position can be immediately grasped on the drawing.
In addition, abnormalities found during navigation can be recorded as annotations or flags in space, and reports can be output.
