The FIFISH app (iOS/Android) provides live 4K streaming, recording, and AI-assisted object detection.
How it compares
FIFISH V6 Expert competes with BlueROV2 (open source, similar depth), Deep Trekker REVOLUTION (inspection focus), and Geneinno Titan in the professional prosumer ROV segment. FIFISH's 4K Sony sensor, polished app ecosystem, and integrated AI features are key differentiators versus the BlueROV2's open-source but less polished interface.
Limitations
- Tether-required (not wireless)
- 200m depth vs professional work-class ROVs at 300-6000m
- Chinese manufacture may face procurement restrictions in some defence/government applications
- AI detection features still maturing for specialised inspection tasks
FAQ
What is the depth rating of the FIFISH V6 Expert?
The FIFISH V6 Expert is rated to 200m depth, suitable for most coastal and offshore inspection applications excluding deep-water work.
Can FIFISH V6 Expert perform manipulation tasks?
Yes. The FIFISH V6 Expert supports a robotic claw attachment for light manipulation tasks including opening valves, collecting small specimens, and repositioning objects.
How does FIFISH V6 Expert compare to BlueROV2?
BlueROV2 offers open-source software and greater extensibility at a similar price point; FIFISH V6 Expert offers a more polished consumer-grade app interface, Sony 4K camera, and integrated AI features. FIFISH is easier to use; BlueROV2 is more customisable.
