The benchmark open-source ROV
The BlueROV2 is the most widely deployed professional-grade underwater ROV in the world — trusted by research institutions, commercial inspection companies and government agencies on every continent. It began as a Kickstarter project and became the platform an entire industry now builds on.
Six T200 thrusters in a vectored arrangement deliver true 6-DOF, near-omnidirectional control. A 1080p low-light camera on a ±90° tilt, dual dimmable Lumen lights and a Bar30 depth sensor make up the core sensing suite — all driven by BlueOS, an open browser-based software stack running on an onboard Raspberry Pi 4. Control it from any laptop or tablet.
The Heavy Configuration Retrofit Kit adds two more thrusters for greater payload stability and vertical force. Add Cerulean Sonar imaging and positioning, the Newton Subsea Gripper, or third-party sensors through the standard WetLink Penetrator system — no custom engineering required.
- 6 × T200 thrusters standard — 8× with Heavy Configuration
- 1080p 30fps low-light camera, 110° FOV, 0.01 lux, ±90° tilt
- 2× (or 4×) Lumen dimmable lights — 1,500 lm each
- BlueOS + ArduSub: Stabilize, Depth Hold, Position Hold modes
- Cockpit GCS: widget-based UI, video recording, joystick support
- 14.8V 18Ah Li-ion battery — 2h normal / ~4h light use
- 25–300m tether options; neutral buoyancy (fresh water)
- Acrylic enclosures (100m) or aluminium (300m) configurable
Built to remove the limits of subsea work
Commercial-grade underwater work used to mean six-figure ROVs, dive teams or chartered vessels. The BlueROV2 was built to take those limits off the table.
💸 Cost barrier
Traditional inspection-class ROVs run well into six figures. The BlueROV2 delivers professional capability from a fraction of that — and you only buy the modules you need.
⚠️ Risk to divers
Currents, confined spaces, contaminated water and depth all put divers at risk. The BlueROV2 keeps people topside while the robot does the work.
🔒 Vendor lock-in
Closed systems trap you on one vendor's roadmap. BlueOS and ArduSub are fully open-source — inspect, extend and integrate without permission.
🧩 Rigid hardware
Most ROVs ship as a fixed package. The open frame, WetLink penetrators and PWM/Ethernet payload bus let you add sonar, grippers and sensors yourself.
Engineered for repeated salt-water deployment
Every component is designed, tested and rated for professional use in the ocean — not adapted from consumer hardware.
Vectored thrust in six degrees of freedom
The BlueROV2 runs on the Blue Robotics T200 — the world's most popular ROV thruster. Six are arranged in a vectored configuration so the vehicle pitches, rolls, yaws and translates in any direction, holding a stable attitude for clean inspection footage even in moving water.
- Flooded brushless T200 design — 300 m depth rated, salt-water proven
- Heavy Configuration adds 2 thrusters for payload stability and vertical force
- Basic ESC per thruster, driven by the Navigator Flight Controller
See clearly where there's almost no light
A 1080p 30fps low-light camera resolves detail down to 0.01 lux — near-total darkness at depth — across a 110° field of view, on a ±90° servo tilt so you can look up at a hull or down at the seabed without re-trimming the vehicle. Two dimmable 1,500-lumen Lumen lights come standard, expandable to four for 6,000 lumens total.
An open frame you can actually build on
The modular HDPE frame is drilled for payloads and leaves the watertight enclosures fully accessible. Choose acrylic tubes for 100 m work or anodised aluminium for 300 m, and route any sensor through the standard WetLink Penetrator system. A Raspberry Pi 4 and Navigator Flight Controller sit inside, with a Bar30 depth sensor, IMU, magnetometers and leak detection onboard.

An open software stack, not a locked black box
BlueOS runs the vehicle, ArduSub flies it and Cockpit (or QGroundControl) puts it in your hands — every layer open-source, inspectable and extensible.
BlueOS — the vehicle's operating system
BlueOS runs on the onboard Raspberry Pi 4 and serves a browser-based control panel to any connected laptop or tablet. Manage autopilot firmware and parameters, stream and record video, monitor system health and install community extensions — no software to install on your machine.
- Browser UI — works from any laptop, tablet or phone on the tether network
- Over-the-air firmware and BlueOS updates with one click
- Extension marketplace for sonar, DVL, mapping and custom tooling
- Live system monitoring, logging and network configuration
A modern ground control station
Cockpit is the modern, widget-based GCS for daily operations — a customisable layout with the live camera feed, a heading compass, depth, voltage and telemetry on a single screen. Pre-calibrated Xbox, DualShock 4 and DualSense profiles mean you can plug in a controller and fly, and record video with a telemetry subtitle track for defensible inspection records. QGroundControl remains available for mission planning and deep parameter tuning.
ArduSub Flight Modes
Three primary modes cover every scenario — from direct manual override to depth-stabilised station keeping.
Manual Mode
Direct, unassisted thruster control. Joystick inputs map directly to thruster outputs with no autopilot correction. Full pilot authority — used when maximum responsiveness is needed.
Stabilize Mode
The autopilot holds roll and pitch level when the joystick is released. The pilot controls heading, depth, and forward motion. Smooth, stable footage without fighting water movement.
Depth Hold Mode
Locks depth using the Bar30 pressure sensor. The pilot moves the ROV horizontally while ArduSub automatically compensates for vertical forces. Ideal for horizontal transect inspection.

Vectored Thruster System & Heavy Kit Upgrade
The BlueROV2 is equipped with patented T200 thrusters, engineered for maximum efficiency and durability in harsh underwater environments. These thrusters deliver a high thrust-to-weight ratio and smooth, precise control, thanks to their vectored configuration. This setup allows the ROV to maneuver effortlessly in any direction, even in strong currents.
The standard BlueROV2 includes six thrusters, but for advanced missions, you can upgrade to eight with the Heavy Configuration Kit. This enhancement provides full six-degree-of-freedom movement and superior stability, making it ideal for carrying heavier payloads or operating in challenging conditions.
Performance Features:
High Thrust Output: Designed for demanding subsea operations
Corrosion-Resistant Materials: Built for long-term reliability
Adjustable Gain Settings: Fine-tune responsiveness for delicate tasks or high-power maneuvers
