Possibly ≤ 1 weekShipping: Days (in-stock kits). Ordered directly from Blue Robotics in California or from its distributors; it arrives partially assembled. Blue Robotics store ↗

Remote control: Connect over the tether's Ethernet link and send MAVLink commands (e.g. pymavlink manual_control or RC overrides) to ArduSub; BlueOS also hosts custom extensions.

Overview

The low-cost, open-source ROV that became the de facto platform for university marine robotics, aquaculture inspection and hobbyist exploration. Released in 2016, it runs the open ArduSub autopilot and BlueOS on a Raspberry Pi, so everything from thruster mixing to camera streams is hackable. It ships partially assembled (6–8 h build) and is endlessly extensible with Blue Robotics' sonar, grippers and third-party payloads.

The default choice for anyone who wants a programmable, repairable ROV.
