Key Features
Enhanced 4.5-Knot Propulsion
Powered by the Q-Motor Pro and a six-motor vector layout, FIFISH X1 enables rapid and precise inspections. Its modular design allows quick thruster swaps, while built-in alert systems provide adaptive protection against overcurrent, overvoltage, and overload.

Stable Hovering at 4.0 Knots — Precise Inspections
FIFISH X1 features forward and downward Q-DVL modules with advanced AI algorithms for precise navigation and stable hovering even in 4.0-knot currents—enabling controlled, accurate inspection runs in the most challenging open-water environments.

15 kg Payload — Four Q-Interface Power Ports
X1 supports the most demanding inspection tasks with a maximum payload capacity of 15 kg and four Q-interface power ports, enabling simultaneous deployment of multiple inspection and NDT tool systems.

1+N NDT & Modular Tool Skids
A modular payload design enables rapid tool changes and integration—within 5 minutes—for maritime and offshore environments. Compatible with a wide range of NDT tools, manipulators, and imaging sonars.
Ultrasonic Thickness Gauge (UTG)
Cathodic Protection (CP) Tool
Multi-parameter Sensor
Water Jet Cleaner

AI Inertial Navigation — U-INS Plus
The U-INS Plus fused navigation system combines advanced hardware and software. Forward- and downward-facing Q-DVL modules deliver stable current resistance, real-time depth control, 3D route planning, and point marking—making underwater inspections smarter and more intuitive.

AI Non-Destructive Measurement (QY-MT)
The AI-driven QY-MT system uses proprietary vision algorithms to deliver millimeter-accurate measurement of offshore structures, subsea pipeline cracks, bridge scour, and hull coating damage. Offline data capture enables one-click non-destructive measurements—setting a global benchmark for underwater inspections.

AI Collision Avoidance
A tri-directional collision avoidance sonar system scans the surrounding environment in real time to prevent collisions. Customizable avoidance distance settings ensure enhanced operational safety when navigating complex subsea platforms and structures.

Direct Power Supply — Uninterrupted 24/7 Operation
FIFISH X1 uses a direct power cable supply, removing battery limitations and enabling continuous 24/7 operation. Ideal for long-duration, high-intensity tasks and continuous monitoring while reducing costs related to operational interruptions and battery replacements.

All-in-One Display — Q-iRC Controller
Optimized for ROV control, HD media, and AI—enabling smarter, faster operations. Features a 7″ Full HD display with up to 1,500 nits brightness, delivering crystal-clear visuals even in direct sunlight. Mission Log Recording, Accessory Window Switching, Real-Time Data Sync, and an all-in-one Accessory Portal are all integrated into a single interface.
