[Inspection Support Technology Performance Catalog] Underwater Drone + 2D Sonar Utilization
Utilizing underwater drones as a new option to visualize bridge pier excavation. *Exhibiting at Japan Drone 2025 / International Construction and Surveying Exhibition.
【Non-contact and Non-destructive Inspection Solution for Scour Using Autonomous Underwater Drones】 This technology utilizes the industrial underwater drone "FIFISH series" manufactured by QYSEA to efficiently check for the presence of scour at bridge pier foundations in rivers. Instead of traditional inspections by divers, the underwater drone autonomously navigates while equipped with a 360-degree camera and high-intensity lights, capturing highly visible images in real-time. This ensures safety, reduces work time, and optimizes costs. 【Scheduled Exhibitions in 2025】 We will showcase our achievements and the latest models in underwater drones. - Japan Drone 2025 Makuhari Messe June 4 (Wed) - 6 (Fri), 2025 - International Construction and Surveying Exhibition (CSPI EXPO 2025) Makuhari Messe June 18 (Wed) - 21 (Sat), 2025

basic information
The FIFISH V6 PLUS is an industrial underwater drone that allows anyone to intuitively perform inspections and tasks underwater. With six thrusters providing omnidirectional movement and attitude control, it ensures high stability even around narrow spaces and complex structures. The dual sonar positioned at the front allows for efficient acquisition of images and data while maintaining distance from the target object. Equipped with a robust body and a large-capacity battery that enables long operating times, it can handle demanding environments. It is widely used for underwater surveys, structural inspections, and educational and training purposes. Body size: 383mm × 331mm × 143mm Weight: 5.0kg Thrusters: 6 (4 vector + 2 horizontal) Degrees of freedom: 6DOF (forward/backward, left/right, up/down movement / pitch, roll, yaw) Maximum speed: 3 knots (approximately 1.5m/s) Maximum diving depth: 150m Operating temperature range: -10℃ to 60℃ Battery: 14,400mAh / 156Wh (Lithium-ion Panasonic 21700) Operating time: Up to 6 hours (in still water) / approximately 1.5 hours (current speed 1m/s) Fast charging: FIFISH quick charge (fully charged in about 1 hour)
