FIFISH E-MASTER Industrial AI Underwater ROV
Inspection, measurement and survey
QYSEA's flagship industrial ROV - Ring-Wing propulsion, four onboard AI software modules, dual hot-swap batteries and 10,000-lumen imaging in one modular, single-operator platform. Unlock your mastery.
One platform for the work that used to need several
The FIFISH E-MASTER is a revolutionary industrial AI underwater robot, engineered for high-precision measurement, inspection and survey in complex marine environments. It brings QYSEA's full engineering stack together - so a single deployment can inspect a structure, take quantitative measurements, navigate autonomously and map the seabed without swapping vehicles.

The E-MASTER in the Field
The problems the E-MASTER was built to solve
Traditional subsea inspection and survey methods come with hard limits. The E-MASTER was designed specifically to remove them.
01High Cost
Crewed vessels, divers and specialist survey gear are expensive to mobilise. One operator and one ROV replace much of that.
02High Risk
Divers in currents, confined spaces and contaminated water carry real risk. The E-MASTER keeps people out of the water.
03Depth & Current Limits
Weaker ROVs lose station in flow. Ring-Wing thrust and Q-DVL hold position to 200 m in up to 3-knot currents.
04Low Precision
Visual-only inspection isn't measurable. QY-MT delivers 99.7% accurate, documented, repeatable measurement.
Ring-Wing Propulsion
An innovative ring-wing motor system that rethinks ROV propulsion - delivering 30% more thrust than conventional layouts from the same power input.
More thrust, more control, in tougher water
Six high-performance metal wing propellers with an expanded blade area are arranged in a ring configuration around the body. The geometry maximises the volume of water each thruster accelerates and smooths thrust across all six axes - giving the E-MASTER a 30% power increase alongside remarkable reliability, wear resistance and corrosion protection.
- Holds station in stronger currents and tows heavier payloads
- Fine-grained omnidirectional control for close-tolerance inspection
- Metal propellers resist the flex and fatigue failures of plastic designs
Four AI Software Modules
The E-MASTER's intelligence is built into four integrated AI systems - each replacing specialist equipment that would otherwise need a separate deployment, operator or budget.
QY-MT - Smart Measurement Tool
QYSEA's AI-powered precision measurement system. Using the forward Q-DVL and laser together with proprietary AI algorithms, operators can analyse and measure underwater objects, fractures and damage with 99.7% accuracy - non-contact, no diver, no specialist calibration rig.
- Dynamic, adaptive, multi-angle measurement at any orientation
- Augmented-reality virtual ruler with customisable on-screen scale
- Re-measure recorded footage offline for inspection reports
- Document crack widths, corrosion areas and structural dimensions
QY-BT - Bathymetric Tool
Automated, precise underwater data collection that lets you survey seabeds, riverbeds and reservoirs and generate customisable 2D/3D topographic maps - deliverable survey data produced during normal inspection dives, with no separate survey vessel.
- Automated 2D/3D seafloor & structure topographic mapping
- Customisable map area and resolution parameters
- Reservoir & basin volume / capacity estimation
- One-click data report generation, export to GIS & reporting tools
U-INS Plus - Underwater Inertial Navigation
A deep-learning underwater inertial navigation system that provides precise position, velocity, heading and attitude - enabling surface-adaptive path planning and autonomous missions. Plan a route, press go, and the E-MASTER executes it without continuous pilot input.
- Subsea automatic navigation from deep-learning position estimation
- Custom inspection routes & survey patterns · one-click return-to-home
- Real-time motion tracking with historical path visualisation
- Custom POI recording & repeatable passes for change detection
AI Diver Tracking
QYSEA's self-developed underwater AI technology automatically identifies and locks onto a working diver in the video feed and follows them through the water - so the pilot can monitor instruments and tether while the ROV handles framing and safety overwatch.
- →Real-time diver identification via onboard computer vision
- →Autonomous follow - no manual pilot input needed
- →Proprietary AI image-filtering algorithm for turbid water
- →Supports dive-safety monitoring & diver-assistance missions
Q-DVL - Dynamic & Steady Hovering
Forward and downward Q-DVL sonar give the E-MASTER the most complete station-holding in the FIFISH range - locking position in current while avoiding collisions and holding altitude.
Hold a precise 3D position - no GPS, no anchor
The Q-DVL measures the ROV's velocity against the water and the seabed, so the flight controller can lock a precise hover for close-range inspection and measurement and resist omnidirectional flow of up to 3 knots - exactly where weaker ROVs drift off target.
- Stable hovering for close-tolerance inspection & QY-MT measurement
- Strong omnidirectional flow resistance up to 3 knots
- Foundation for U-INS Plus autonomous navigation & QY-BT mapping
Station Lock Hovering
Holds a fixed 3D position against current - stable enough for measurement and detailed close-up inspection.
Smart Collision Avoidance
Forward & downward sonar continuously scan for obstacles, alert the pilot and brake before impact in confined spaces.
Altitude / Distance Lock & Track
Holds a set height above the seabed or distance from a surface and follows the bottom contour for consistent survey passes.
Professional 4K Imaging & 10,000-Lumen Lighting
Engineered for industrial-grade documentation - wide-field macro capability, extreme illumination and RAW capture for defensible inspection records.
See more, in worse water, in finer detail
A large 1/1.8-inch CMOS sensor captures 4K UHD video and RAW stills, with a 176° super-wide surface view and 146° underwater panoramic perspective. Focus as close as 10 cm for welds, corrosion and coating defects - and AI auto-focus keeps the subject sharp even as sediment drifts through the frame.
1/1.8" CMOS Sensor
A large sensor gathers maximum light in poorly-lit deep environments, staying clean where smaller sensors produce noisy, unusable imagery.
176° / 146° Dual FOV
176° surface view for situational awareness on descent; 146° underwater panoramic to capture full pipe diameters, tank walls and hull sections in one frame.
10 cm Macro Focus
Focus as close as 10 cm for detailed close-ups of welds, corrosion pitting, crack propagation, fouling and coating defects.
10,000-Lumen LEDs
Multi-lamp LED arrays deliver 10,000 lumens across a 160° beam - near-shadowless light at three adjustable intensity levels.
AI Auto-Focus in Turbid Water
AI focusing holds sharpness even as particles and sediment cross the lens - critical in silty, post-disturbance and high-turbidity water.
RAW Format Capture
Full RAW preserves maximum sensor data for professional post-processing - essential for engineering reports and regulatory submissions.
Fluid Modular Architecture
Every major component is field-replaceable in minutes - directly cutting downtime and total cost of ownership over the ROV's service life.
Hot-swap batteries - no shutdown, no reboot
An upgraded circuit design carries two batteries with advanced hot-swap technology, so you can alternate a depleted unit for a charged one without powering down or restarting. With the optional Q-Energy Station, 150 minutes of standard runtime and a 50-minute charge to 90% keep back-to-back deployments running.
Component Swap in ~5 Minutes
Motor, imaging, lighting and battery modules are field-replaceable with minimal tools. Batteries and accessories release in seconds; a full part swap takes about five minutes - no workshop required.
Dual Load Interfaces
Independent top and bottom load interfaces mount accessories on both surfaces. With professional expansion docks the E-MASTER carries up to 6 operational tools at once.
Q-Energy Station
The optional portable smart charging platform manages your battery rotation - keeping spares charged and ready for continuous deployment sessions.
