The E-GO in the Field
The problems the E-GO was built to solve
Professional underwater work demands precision, reach and fast turnaround - without the cost and risk of crewed survey operations. The E-GO is engineered around exactly those constraints.
01Slow Mobilisation
Reconfiguring conventional ROVs eats into dive windows. The E-GO swaps any accessory in roughly 9 seconds - reconfigure between dives, not between days.
02Diver Risk
Currents, confined spaces and low-visibility water carry real risk. The E-GO keeps people out of the water for inspection, search and survey.
03Current & Drift
Weaker ROVs lose station in flow. Ring-Wing thrust and Q-DVL station lock hold a precise 3D position for steady close-up work.
04Low Precision
Visual-only inspection isn't measurable. QY-MT delivers AR-ruler measurement to within 1 cm, documented and repeatable.
Ring-Wing Propulsion - 30% More Power
The E-GO uses the same Ring-Wing motor architecture as the flagship E-MASTER - delivering a 30% power increase over the FIFISH V6 EXPERT through six metal wing propellers arranged for maximum efficiency.
More thrust, more control, in tougher water
Six high-performance metal wing propellers with expanded blade area are arranged in a ring configuration around the central axis. The geometry maximises the volume of water each thruster accelerates and smooths thrust across all axes - giving the E-GO 30% more total thrust than the V6 EXPERT at equivalent power, with metal construction that resists the flex fatigue of plastic designs.
- Holds station in stronger currents and tows heavier payloads
- 360° six-degree-of-freedom omnidirectional control
- Metal propellers built for professional continuous-use cycles
Q-STEADY 3.0 - Latest-Generation Self-Stabilisation
QYSEA's most advanced stabilisation system combines electronic image stabilisation, AI visual station lock and adaptive flow response into a single seamless control layer - so the pilot can focus on the task, not on holding position.
Electronic Image Stabilisation
Real-time correction driven by the onboard IMU compensates for thruster vibration, tether pulses and turbulence before they reach the recorded footage - smooth, report-quality imagery in active conditions.
AI Visual Station Lock
Tap any subject in the live feed and the AI vision lock tracks and centres it automatically, holding the framing as ROV and subject move - single-touch, no constant manual correction during close-up work.
Adaptive Flow Response
Q-STEADY 3.0 continuously reads current conditions and adapts the thruster response profile in real time - the ROV feels more planted and predictable across a wider range of conditions than earlier generations.
Depth Lock
Pressure-sensor depth lock holds the ROV at a fixed depth while the pilot controls horizontal movement - essential for consistent survey passes and structure traversal.
Posture Lock
Lock the body attitude at any angle - level, tilted or angled to a surface - so the pilot focuses on positioning without the ROV drifting back to a default orientation.
Auto-Cruise · Predefined Paths
Programme survey routes or inspection transects in advance and let the E-GO execute them autonomously - consistent, repeatable coverage that reduces pilot workload.
Q-DVL Station Lock & Smart Navigation
Sonar-based Doppler velocity logging keeps the E-GO precisely positioned in three dimensions - the pilot holds a fixed station while the flight controller counteracts current drift, avoids obstacles and holds altitude automatically.
Hold a precise position for steady, measurable work
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 QY-MT measurement - exactly where weaker ROVs drift off target. It is the foundation for collision avoidance, altitude lock and repeatable survey passes.
- Station lock hovering - precise 3D position hold without GPS
- Smart collision avoidance - proximity alerts and auto-brake
- Altitude & distance lock - constant height or standoff from target
- Optional 4D Distance Lock Module for enhanced spatial awareness
Precise Manoeuvring
Six-degree-of-freedom control with Ring-Wing thrust - fine, omnidirectional movement for close-tolerance inspection.
Hot-Swap Battery (In Air)
Alternate a depleted battery for a charged one on deck without powering down the system - in air, not while submerged.
Fast Mobilisation
Compact, modular and quick to pack - deploy from small vessels, jetties and shoreline sites without heavy support gear.
Full AI Software Suite
The E-GO carries the complete QYSEA AI software ecosystem - the same suite found in the E-MASTER - delivering precision measurement, bathymetric mapping, autonomous station holding and intelligent tracking in a single platform.
QY-MT - Smart Measurement Tool
AI-powered non-contact measurement directly from the live camera feed. Quantify crack widths, corrosion areas, structural gaps and object dimensions - with an AR ruler accurate to within 1 cm - in real time or during post-dive review.
- AR Ruler with up to 1 cm accuracy, overlaid on live video
- AR area measurement of defects and features
- Multi-angle measurement capability
- Real-time measurement during the dive or offline on recorded footage
- Results exportable for inspection reports and engineering documentation
QY-BT - Bathymetric Survey Tool
Automated 2D and 3D seafloor topographic mapping during normal inspection dives - generating survey deliverables without a separate survey vessel or specialist mapping ROV.
- Automated 2D / 3D seafloor map generation
- Customisable survey area and resolution
- Reservoir and basin volume / capacity estimation
- Single-click data report generation
- Standard export formats for GIS and engineering tools
Q-DVL - Doppler Velocity Log Station Lock
Sonar-based velocity measurement keeps the E-GO precisely positioned in three dimensions - the pilot holds station and focuses on inspection, measurement or manipulation while the flight controller counteracts current drift automatically.
- Station lock hovering - precise 3D position hold without GPS
- Smart collision avoidance - proximity alerts and auto-brake
- Altitude lock - maintain constant height above seabed
- Distance lock - maintain consistent standoff from a target surface
AI Vision & Tracking Systems
The E-GO's AI vision systems automate target tracking, image-quality enhancement and biological monitoring - with fish counting and detection among the AI capabilities QYSEA lists for the platform.
- AI Visual Station Lock - single-touch subject lock and auto-tracking
- AI Diver Tracking - identify and autonomously follow a working diver
- AI dehazing algorithm - real-time image clarity in turbid water
- AI underwater image enhancement - colour correction and contrast
- AI fish detection & counting for biological monitoring
Over-the-Air (OTA) Updates
The E-GO's software capabilities expand through OTA firmware updates - new AI functions are delivered directly to existing hardware, so your ROV becomes more capable over its operational life without hardware changes.
Professional 4K Imaging & 10,000-Lumen Lighting
Engineered for industrial inspection documentation - a large sensor, wide panoramic view, extreme close focus and powerful dual-LED illumination across the full field of view.
See more, in worse water, in finer detail
A large 1/1.8-inch CMOS sensor captures 4K/30fps 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 dehazing keeps the subject clear even as sediment drifts through the frame.
1/1.8" CMOS · 4K/30fps
A large-format sensor gathers maximum light in the reduced-illumination deep environment, recording 4K detail for defensible inspection documentation - including RAW stills.

10,000-Lumen · 2 LEDs
Two 5,000-lumen LED modules deliver 10,000 lumens across a 160° field of view, at three adjustable intensity levels for varying proximity and water clarity.
Modular Architecture - 9-Second Accessory Swap
Field configuration changes should never hold up operations. Every accessory connects and disconnects in seconds; every major component is field-replaceable without specialist tools.
Reconfigure between dives, not between days
A standardised quick-release interface lets a trained operator install or remove any payload in roughly 9 seconds. Two 69.12 Wh batteries deliver 2.5+ hours of operational time and are hot-swappable in air - alternate a depleted unit on deck without shutting the system down, then redeploy with a fresh pack. 90% charge in about 1 hour keeps spares ready.
Note: Hot-swap battery replacement is supported in air environments only - not while the ROV is submerged. Plan battery rotations between dives accordingly.
9-Second Accessory Swap
The standardised quick-release interface lets an experienced operator install or remove any payload in approximately 9 seconds - reconfigure in the time it takes to discuss the next task.
Up to 6 Tools · 5 kg Payload
With an expansion dock the E-GO carries up to 6 operational tools at once and a 5 kg underwater payload - sonar, sensors, samplers and a robotic arm in a single mission profile.
Integrated Aluminium Housing
A pressure-, corrosion- and crystallisation-resistant aluminium core tank with a biomimetic tail fin reduces drag and withstands the loads of repeated professional deployment better than polymer housings.
A Versatile Underwater Workhorse
The E-GO's combination of AI intelligence, compact form, 9-second tool swaps and a broad sonar accessory range makes it a versatile choice across professional inspection, monitoring and survey work.
Bridge & Infrastructure Inspection
Survey piles, abutments, culverts and civil structures to 100 m. QY-MT documents measurable defects; QY-BT maps seabed conditions; side-scan sonar reveals scour and buried utilities.
