CHASING X Smart Omnidirectional Deep-Sea ROV
CHASING X - three-quarter view
The CHASING X is a flagship industrial underwater drone built for the toughest water - 350 m depth, the world-first AnchorX anti-current system, OctoDrive 8-thruster propulsion and 12,000-lumen 4K imaging in a single rugged platform. Hold station where other ROVs drift.

A deep-sea workhorse that stays put in current
Most observation-class ROVs lose the target the moment the water moves. The CHASING X was engineered around that problem - pairing the world-first AnchorX anti-current system with an eight-thruster OctoDrive layout so it can hold a precise position in flows up to 4.5 knots from any direction, down to 350 metres.

The problems the CHASING X was built to solve
Tidal flow, depth, darkness and turbidity are where ordinary underwater drones fail. The CHASING X was designed specifically to keep working through them.
01Strong Current
Light ROVs drift off target in moving water. AnchorX and OctoDrive hold station in up to 4.5-knot flow from any direction.
02Deep & Dark
At 350 m there is no ambient light. Twin 6,000-lumen floodlights deliver 12,000 lm of near-shadowless illumination.
03Blind Spots
A single fixed camera misses framing in confined or overhead work. A 220° e-PTZ camera keeps the subject in view at any attitude.
04Lost Time
Battery swaps and re-rigging stall a shift. Tool-free quick-swap power and optional shore supply keep the ROV in the water.
AnchorX - Smart Omnidirectional Anti-Current
AnchorX continuously perceives the direction and speed of the current, then deploys counter-thrust across all eight thrusters to lock the ROV in place - no operator input, no drift.
Stay locked on target while the water moves
Conventional ROVs resist current from one direction at best. AnchorX uses real-time flow perception and the OctoDrive vectored layout to counter currents from every direction at once - holding a stable working position in tidal races, river outflows and exposed offshore sites.
- Real-time current direction & speed perception
- Automatic counter-thrust - hands-off station keeping
- Ideal for tidal, offshore and high-flow inspection sites
Horizontal Flow Resistance
Held steady against a strong lateral current - the hull and thrusters absorb the push without losing the target.
Vertical Flow Resistance
Maintains depth and attitude through up-welling and down-welling flow for stable vertical-face inspection.
Eight Thrusters · Full Six-Axis Control
The OctoDrive layout puts eight vectored thrusters around the hull, giving the CHASING X complete spatial authority - move in any direction, hold any attitude, and flip a full 360°.
Go anywhere, hold anything
With thrust available on all six degrees of freedom, the CHASING X surges, strafes, dives, yaws, pitches and rolls with equal authority. That means precise close-tolerance positioning against a structure, smooth tracking shots, and the ability to invert completely for overhead and undercut inspection.
- Forward, lateral and vertical translation on demand
- Pitch and tilt control for angled inspection lines
- 360° roll and one-click flip for overhead work
Forward & Backward
Drive straight onto a target and back off with fine throttle control.
Lateral Translate
Strafe sideways along a wall or hull without changing heading.
Float & Dive
Climb and descend on a stable vertical line for depth-stepped passes.
Turn Left & Right
Yaw in place to scan a full circle from a single hover point.
360° Roll
Roll the whole vehicle through a full circle for any viewing angle.
One-Click Flip
Invert instantly for overhead, undercut and ceiling inspection.
Dual-Camera 4K · 12,000-Lumen Lighting
A primary 8 MP 4K wide-angle camera works alongside a unique 220° e-PTZ hemispheric camera - so the subject stays framed and level no matter how the ROV is oriented.
See everything, document it in 4K
The main 1/1.8" CMOS camera shoots 4K UHD at 30 fps and slow-motion FHD at 120 fps through a wide 160° lens. The second e-PTZ camera adds a 220° hemispheric field that electronically corrects framing as the ROV changes posture - paired with a one-click 360° flip for true all-around capture.
Main Camera - 8 MP 4K
1/1.8" CMOS, F2.2, 160° FOV. 4K at 30 fps, FHD slow-motion at up to 120 fps, and 8 MP stills for inspection documentation.
e-PTZ - 220° Hemispheric
1/1.8" CMOS, F2.0, 220° field. Electronic pan-tilt keeps framing level and composed regardless of the ROV's attitude.
360° One-Click Flip
Invert the vehicle with a single tap for all-around shooting - frame any angle without repositioning the hull.
12,000-Lumen Floodlights
Two 6,000-lumen LED floodlights with stepless dimming light the scene for work in complete darkness at 350 m.
One-Click Live Broadcast
Stream the live feed straight from the WSRC controller to an operations centre or audience in real time.
Open SDK Platform
A secondary-development SDK lets you integrate AI computer vision, inspection analytics and custom payload logic.
A Waterproof Command Deck
The WSRC integrated controller puts the live feed, vehicle telemetry and one-touch functions on a built-in IP65 display - ready for the deck in any weather.
Everything on one screen, rain or shine
The WSRC ships with an integrated waterproof display, so there's no tablet to rig or rain-cover to fit. A 7,000 mAh battery keeps it running six hours or more, and USB and HDMI outputs feed external recorders and monitors for client viewing.
- Built-in Wi-Fi connected display - no separate tablet
- USB & HDMI out for external recording and monitors
- One-click live broadcast and capture controls
Expand the CHASING X
Tool-free modular mounts let the CHASING X carry the professional payloads a job demands - acoustic imaging, precision navigation, positioning and intervention.
CHASING publishes 26 approved add-ons for the X. These are the ones that matter for professional work - everything here mounts tool-free and is quoted with the vehicle.
Blueprint Oculus Multibeam
M370S for long-range search, M750d as the all-round inspection head, M1200d for high-resolution close work. Supplied as a complete kit with the X interface.
Micron Gemini Imaging Sonar
Gemini kit and the compact MKS7 head - proven mechanical-scanning imaging for zero-visibility navigation and target detection.
Ping 360 Scanning Sonar
Entry-level 360° mechanical scanning sonar kit - obstacle awareness and orientation in silty water without a survey-grade budget.
Cerulean Omniscan 450 FS
Forward-scan / side-scan sonar approved by CHASING for the X - and a brand we supply directly, so the integration and the support sit with one vendor.
Water Linked DVL A50
Doppler Velocity Log that adds velocity-over-ground data for tighter station-holding and dead-reckoning navigation. AnchorX works without it; the DVL comes fitted in the Advanced and Professional Sets.
USBL Underwater Locator Kit
CHASING's own acoustic positioning kit - plots the vehicle's real position on a GPS-referenced chart during deep operations.
Cerulean USBL ROV Locator
Alternative USBL tracking head, also supplied by SepcoTech - useful where the survey software or the vessel spread already speaks Cerulean.
UVision UScanner
Specialist scanning payload on CHASING's approved list for detailed structural and seabed inspection tasks.
e-PTZ & Auxiliary Camera
The 220° hemispherical e-PTZ head (fitted in the Advanced and Professional Sets) plus a second auxiliary camera for a simultaneous alternative angle.
Grabbers & Claws
Grabber Claw A, the heavier Grabber Arm 2, and the circular and salvage circular claws for irregular objects and recovery work.
Samplers & Laser Scaler
Water sampler with 500 ml bottles, sediment sampler for seabed cores, and the laser scaler for contact-free sizing of defects and growth.
Topside & Integration
Adapter box for third-party payloads, the full Control Console for two-operator working, and the open SDK for custom sensor integration.
Choose Your Set
Three standard configurations - from a complete inspection platform to a continuous-operation professional rig. We'll tailor the exact payload to your mission.
Standard Set
Battery-powered, self-contained. The working baseline.
- CHASING X ROV
- WSRC waterproof screen controller
- Reel with 400 m tether
- 1,000 Wh battery
- Carrying case
- Accessory backpack
Advanced Set
Everything in the Standard Set, plus the two modules that turn it into a survey tool:
- Water Linked DVL - station-hold and dead-reckoning navigation
- e-PTZ 220° hemispherical camera
C-SPSS Professional Set
Shore-powered for continuous operation - note that the C-SPSS replaces the reel and battery rather than adding to them:
- CHASING X ROV + WSRC controller
- Shore-based power supply system (C-SPSS)
- Water Linked DVL + e-PTZ camera
- Carrying case + accessory backpack
- No battery swaps, no runtime ceiling
Running long shifts from a vessel or quay? The C-SPSS set removes the battery limit entirely - but you lose the untethered-from-shore flexibility of the reel-and-battery build. Tell us the working pattern and we will say which one actually fits.
