Class definition
Water-based robots swim on the surface (B1) or dive under it (B2). A teleoperated underwater vehicle is a robotic device; BlueROV2 is labeled accordingly. BlueBoat ships with autonomous GPS waypoint navigation. [A1] [M3]
Surface — BlueBoat uncrewed surface vessel
Endurance is the vendor condition at 1 m/s, about 30 W, with no payload.
Battery mass and comparability
Battery mass counts against the same 15 kg allowance as the mission payload; neither number is comparable to BlueROV2 depth, tether, or underwater payload definitions.
