Underwater ROV
BlueROV2 The World's Most Popular Open-Source ROV
BlueROV2 - three-quarter view
A professional-grade underwater ROV engineered for real-world inspection, research, and exploration. Six T200 thrusters, 1080p low-light camera, BlueOS software, and an open accessory ecosystem - from €4,606.
Every part, and why it's there
Nothing on this vehicle is a sealed black box - each component is a part you can buy, service and replace on your own bench. Hover or tap a number to trace it to the hardware.
- 01LightingYou chooseLumen Subsea Light1,500 lumens each on a 135° beam, dimmable. Two give 3,000 lumens, four give 6,000.
- 02TrimMachined buoyancy foamTrimmed slightly positive, so a power failure floats the vehicle back to you. 1.2–1.4 kg payload capacity.
- 03StructureModular HDPE frameCorrosion-proof and drilled for payloads, with the enclosures left open on the bench. 457 × 338 × 254 mm overall.

The 4K Cam turns the BlueROV2 you already own
into a 4K inspection platform.
Blue Robotics’ new piloting camera is a straight retrofit for the standard 1080p USB camera - a Sony IMX678 sensor at 3840 × 2160, motorised zoom and focus, an integrated tilt servo, and 0.001 lux low-light sensitivity. It keeps piloting latency at 225 ms in 4K, so the picture gets four times sharper without the feed going soft or laggy.

The 18 Ah batteries are the hard part.
We ship them with the ROV.
The BlueROV2 does not include a power source, and the 14.8 V 18 Ah Li-ion pack it runs on is the single item most likely to hold up an order. At 266 Wh it sits far above the 100 Wh air-freight threshold, so it can never move as ordinary cargo: on its own it ships as UN3480 Class 9 dangerous goods, and packed together with the vehicle as UN3481. Either way it needs certified packaging, a shipper’s declaration, trained personnel and a carrier willing to take it.
That is the part you cannot improvise - a lithium pack is never simply put in a box and sent, which is exactly why it is worth buying it from someone who is set up for it. We hold the genuine Blue Robotics packs in EU stock, dispatch them within 48 hours, and ship them with the vehicle under UN3481 as a certified dangerous-goods shipper - one order, one delivery, charger included, and no separate lithium consignment left for you to arrange.
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.
01Cost 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.
02Risk 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.
03Vendor lock-in
Closed systems trap you on one vendor's roadmap. BlueOS and ArduSub are fully open-source - inspect, extend and integrate without permission.
04Rigid 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. Lighting is chosen separately: two dimmable 1,500-lumen Lumen lights give 3,000 lumens, four give 6,000.
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.

Manipulation
Newton Subsea Gripper
A single-function open/close gripper rated to 300 m. It bolts to the BlueROV2 frame and is driven from one PWM output on the Navigator flight controller - the same kind of channel a light uses - so it needs no extra electronics inside the enclosure.
- 300 mdepth rated
- 1PWM channel
Tip Check you have a free PWM output before you order - lights, a tilt servo and a gripper all draw from the same 16.

Newton Sediment Sampler
Collect sediment or water samples remotely. A spring-loaded 60 ml chamber, rated to 300 m, triggered from the BlueROV2 control system - so a sample is one button press with the vehicle still on station.
- 60 mlsample volume
- 300 mdepth rated
Tip This is an attachment for the Newton Gripper, not a standalone tool - budget for the gripper with it on a first order.

Bar30 Depth / Pressure Sensor
The high-resolution pressure and temperature sensor that gives the BlueROV2 its depth reading and depth-hold. Rated to 300 m with 2 mm resolution, on the I²C bus.
- 300 mdepth rated
- 2 mmresolution
Tip Every BlueROV2 already has one fitted - order this as a spare. Working shallower than 10 m? The Bar02 (BR-100891, €75) resolves to 0.16 mm on the same interface.

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.
