Smart Seabed Mapping

Comprehensive Visual Inspections

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.

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.
