FIFISH ROVs support various sampling tools and sensors for efficient data collection at multiple depths and points. Integrated with the FIFISH app, they provide real-time monitoring data, enabling quick condition assessment.
Efficient in Confined Spaces
FIFISH ROVs are compact and lightweight, combining 360° full-dimensional movement and precise hovering capabilities. They can easily access narrow spaces that divers may be unable to reach.
Lightweight & Compact
Efficient in Confined Spaces
The powerful motors give QYSEA ROVs over 3 knots of thrust. Paired with QYSEA’s self-developed Q-DVL sonar system, the ROV can hover automatically in turbulent conditions. Even with multiple sensors or accessories, it adjusts its posture for stable, safe, and efficient operations in high-flow environments.

QYSEA's self-developed U-INS inertial navigation system provides precise underwater positioning, location recording, 3D path planning, autonomous cruising, and one-click return-to-home. It enables rapid large-area inspections, saves anomaly locations, and allows for easy matching of image data, samples, and coordinates, facilitating high-frequency repeat inspections.
Precision Underwater
Evaluation & Monitoring
QY-BT smart depth mapping system supports seabed, riverbed, and reservoir mapping, generating 2D/3D maps and estimating capacity. With one-click report generation, it streamlines mapping, boosts efficiency, and provides reliable data for ecological monitoring.
Smart Navigation & Positioning
FIFISH ROVs deliver advanced capabilities for marine conservation inspections, meeting all underwater observation needs with precision and efficiency, ensuring sustainable monitoring of marine ecosystems.

Success Cases
AI Diver Tracking Demonstration — Seawork International 2025
At Seawork 2025 in Southampton, QYSEA debuted its vision-based AI Diver Tracking on FIFISH ROVs.
The feature auto-locks on one or more divers, keeps a steady 0.5–1.5 m stand-off, and shifts camera angles with no joystick input.
Open-water trials later showed 30 minutes of smooth, hands-free tracking in moderate currents—boosting safety and slashing operator workload for inspections, SAR, and training.
