Product Description

The BlueROV2 is the most capable, flexible, and affordable ROV on the market. The 6-thruster vectored configuration, coupled with strong static stability, provides a vehicle that is smooth and stable, yet highly maneuverable. The BlueROV2 provides the capabilities of a high-end mini-ROV at the price of the most basic commercial ROVs.

BlueROV2 – “Dare to Explore”


  • Live 1080p HD video
  • Highly maneuverable vectored thruster configuration
  • Stable and optimized for inspection-class and research-class missions
  • Easy to use, cross-platform user interface
  • Highly expandable with three free cable penetrators and additional mounting points
  • Standard 100m depth rating and up to 300m tether available
  • 6 T200 Thrusters and Basic ESCs for a high thrust-to-weight ratio
  • Quick-swappable batteries for all-day use
  • Highly flexible topside enclosure for a clean connection from the the BlueROV2 to a computer

The vehicle comes in kit form and is partially assembled to make the user assembly as straightforward and enjoyable as possible. There is no soldering, potting, or gluing involved!

The BlueROV2 is our flagship product. It comprises many of our other products including our T200 Thrusters, 3″ and 4″ Series watertight enclosures, Bar30 pressure sensor, Fathom-X Tether Interface (FXTI), and our Fathom tether and tether interface electronics. Many of these products have been on the market for quite a while and have proven themselves through thousands of successful hours of operation in the field. The BlueROV2 continues this legacy with high-quality parts, a meticulous design, and rugged reliability.

Leveraging the effort that has gone into the ArduPilot project and related hardware projects, the BlueROV2 uses the open-source ArduSub software and the Pixhawk autopilot, providing autonomous capabilities rarely seen in mini-ROVs and hackability paralleled by none. The software is actively developed and improved by Blue Robotics and other contributors, with constant upgrades and improvements to make the BlueROV2 even better. The included Advanced Electronics Package provides a high-speed Ethernet connection with the Fathom-X tether interface and a Raspberry Pi companion computer for additional processing power. It provides live 1080p HD video directly to a computer or tablet and flexibility for future expansion.

QGroundControl Interface for ArduSub and the BlueROV2.

The BlueROV2 is offered with several configurable options. All of these options are user-upgradeable at a later time.
  • The Fathom Tether is available in a variety of lengths up to 300 meters (984 feet).
  • The Lumen Lights are optional and either one or two pairs can be used. Each set is ready for installation and each individual light outputs 1500 lumens, the brightness of a car headlight.

The BlueROV2 ships without batteries due to shipping restrictions. We recommend our Lithium-ion Battery (14.8V, 18Ah) or other 4S Li-po batteries that can fit inside a 3″ inner diameter tube. Get a few for extended operation.
