The underwater world in the Baltic States is full of challenges – low visibility, variable temperatures, and complex hydrological conditions. BlueRobotics BlueROV2 has become a global standard, offering high-end performance at an affordable price, which is especially important for the Latvian engineering, scientific and commercial sectors. It is not just a robot; it is an indispensable tool for professionals who need precision where human capabilities reach their limits.
🛠️ Technical architecture and modularity
BlueROV2 is based on an open source platform (ArduSub), which provides unparalleled modularity. Depending on the complexity of the task, the robot can be configured in two main ways:
- Vectored-6 configuration: Standard model with six engines (T200 thrusters) providing full motion control in 5 axes.
- Heavy Configuration (8 engines): An additional two vertical motors increase lifting capacity and stability, providing 6 degrees of freedom (6-DOF) – the robot can tilt (pitch/roll), which is critical when inspecting complex structures or working in strong currents.
Main technical parameters:
- Depth: Standard 100m (modifiable up to 300m).
- Videos: 1080p HD camera with low latency and adjustable tilt angle.
- Lighting: Powerful LED lights (up to 6000 lumens), which are essential in the dark lakes of Latvia.
- Data transmission: Real-time data via a durable neutral buoyancy cable (tether).
🛰️ Sensors and accessories: Vision beyond the limits of visibility
The turbidity of the Baltic waters requires specific equipment. BlueROV2 can be equipped with a range of sensors that make it a full-fledged underwater laboratory:
| Sensor / Device | Function and application |
| Scanning Sonar (Ping360) | Replaces vision. Allows you to "see" through fog, identify objects and obstacles within a radius of up to 50m. |
| DVL (Doppler Velocity Log) | Precise positioning. Measures speed relative to the bearing, allowing the robot to automatically maintain position in the stream. |
| USBL Positioning | Underwater GPS. Allows the operator to see the exact location of the robot on the map in real time. |
| Water quality sensors | Measures pH, oxygen, salinity and turbidity (critical for fish farms and science). |
| Manipulator (Newton Gripper) | Mechanical arm for taking samples, hooking ropes or lifting objects. |
| Altimeter (Ping) | Accurate rangefinder for bathymetry mapping. |
🛡️ Support for diver operations in the Baltic Sea and inland waters
The conditions of the Baltic Sea and inland waters – cold, currents and often zero visibility – pose high risks for divers. The integration of BlueROV2 into the diving team is a safety and efficiency multiplier:
- Pre-immersion reconnaissance: The robot assesses hazards (nets, debris, structural stability) before a person enters the water, saving time and resources.
- Security monitor: During operation, the ROV serves as a stationary observation station, transmitting video to the surface team, ensuring continuous monitoring of the diver.
- Resource optimization: ROVs perform time-consuming search operations over large areas, while the diver is only involved for precise physical manipulation, reducing the risks of decompression sickness.
📍 The best places to use it in Latvia and the Baltics
- Ports (Riga, Ventspils, Liepaja): Inspection of pier walls, piles and ship hulls, even when visibility is close to zero (using sonar).
- Daugava HPP cascade: Searching for cracks in concrete structures and inspecting turbine grids at great depths (e.g. Plavinas HPP).
- Bridge supports: Regular monitoring of leachate and structural erosion in Latvian rivers after spring floods.
- Wind farms and cables: Monitoring of foundations and underwater communication cables of Baltic Sea wind farms.
- Aquaculture: Monitoring the integrity of fish farm networks and the condition of fish without direct involvement of employees in the water.
