Thrusters, Actuators, and Lights
Thrusters
These thrusters use our patented flooded motor design, which makes them powerful, efficient, compact, and affordable. They use three-phase brushless motors optimized for underwater use, and are controlled by a sensorless brushless electronic speed controller (ESC). Bidirectional ESCs (like our BasicESC) can run a thruster both forwards and in reverse.| Thruster | Electrical | Max Thrust (FWD/REV) | Propeller | Dimensions | Weight (w/ cable) | 3D Models |

Speed Controllers (ESCs)
These bi-directional electronic speed controllers allow controlling brushless DC motors like those used in our thrusters. They are controlled by a servo-style PWM signal, where a pulse-width of 1100 μs corresponds to max reverse, 1900 μs max forward, and 1500 μs (+/- 25 μs of deadband) is stopped.| ESCs | Voltage | Max Current | Signal Voltage | Update Rate | 3D Models | Documents | Firmware |

Enclosures, Buoyancy, and Ballast
Watertight Enclosures
These configurable watertight enclosures are great for all kinds of marine robotics applications. Modular end-caps give you options, with clear and flat end-caps with holes for cable penetrators and sensors, and domes for cameras.In the 3D Models, M refers to Metal (aluminium), and P refers to Plastic (acrylic or polycarbonate).

Buoyancy and Ballast
These buoyancy foams and ballast weights can help to balance a vehicle by shifting its center of volume (buoyancy) and center of mass (gravity). With both points in the same location a vehicle is optimised for pitch and roll rotations, whereas with CoB above CoG there is a self-righting effect that keeps the vehicle upright.| Component | Density | Weight (in air) | Net Buoyancy (Lifting Force) | Tested Depth | Material | Dimensions | 3D Models | Documents |
