Unique technical solutions from DREVO River Rover Recovery
Next-generation technologies for environmentally friendly bottom cleaning and restoration of aquatic ecosystems
The main ideaWOOD River Rover RecoveryThe platform's unique feature is that it doesn't operate like a dredger or a dredge, which would disturb large volumes of soil. Instead, it acts as a high-precision robotic system, extracting only the necessary material while preserving the natural structure of the seabed as much as possible.
1. DREVO Smart Sediment Recovery
Intelligent removal of only the dirty layer
Instead of completely removing bottom sediments, an automatic depth control system is used.
The complex includes:
multibeam echo sounder;
subsurface scanner;
density sensors;
cameras;
artificial intelligence.
The system determines:
thickness of the contaminated layer;
the boundary between clean and contaminated sludge;
sampling depth.
The suction head automatically maintains the required depth with an accuracy of a few centimeters.
Advantages
the natural bottom is preserved;
the volume of material removed is significantly reduced;
habitat destruction is minimized.
2. Floating Suction Head
Floating adaptive suction head
Instead of a rigid pipe, a flexible self-adapting head is used.
She:
follows the relief;
slides over rocks;
does not bury itself in silt;
automatically adjusts the pressing force.
Used:
hydraulic suspension;
pressure sensors;
laser rangefinders.
3. AI Bottom Classification
Before starting work, artificial intelligence classifies the bottom type.
The following are determined:
sand;
open;
gravel;
stones;
peat;
wood;
man-made objects.
For each type, the cleaning technology is automatically selected.
4. Multi-stage material separation system
The removed soil goes through several successive stages.
First stage
Large items:
stones;
wood;
plastic;
bottles.
The second stage
Vibrating sieves.
The material is separated into fractions.
The third stage
Hydrocyclones.
Separate:
sand;
open;
clay.
The fourth stage
Magnetic separation.
Extracted:
iron;
steel;
cast iron.
Fifth stage
Eddy current separation.
Separated:
aluminum;
copper;
brass;
bronze.
The sixth stage
Optical sorting.
Computer vision distinguishes between:
wood;
plastic;
glass;
ceramics;
stone.
5. WOOD Wood Recovery AI
A unique system for searching for bog wood.
Used simultaneously:
side sonar;
subsurface radar;
acoustic tomography;
magnetometer (to exclude metal objects);
neural network.
AI is able to assess:
dimensions;
probable type of wood;
depth of occurrence;
expected value.
6. Air Lift Recovery System
Instead of heavy lifting, use:
soft lifting cylinders;
electric compressors;
intelligent buoyancy control.
After securing the wood or boulder:
The cylinders gradually lift the object.
This allows to significantly reduce the load on the manipulator.
7. Adaptive Recovery Arms
The manipulator has automatically changeable grips.
For example:
soft grip for wood;
powerful grab;
magnetic grip;
vacuum gripper;
hydraulic pliers;
mesh bucket.
Tool replacement occurs automatically.
8. WOOD Micro Recovery
For searching for small objects.
Used:
inductive sensors;
high frequency metal detector;
computer vision;
magnetic rollers;
hydrocyclone.
Allows you to find:
coins;
decorations;
tools;
equipment parts.
When working in areas where archaeological finds may be present, the system must operate in accordance with local legislation and stop to allow specialists to be called in.
9. Dynamic Water Cleaning
After being sucked in, the water undergoes multi-stage purification.
Used:
cyclone;
mesh filters;
sand filters;
carbon filters;
ultraviolet treatment.
After quality control, the purified water is returned back.
10. Underwater 3D scanner
During the work, a digital model of the bottom is created.
The following are recorded:
depth;
stones;
wood;
pits;
bottom sediments;
artificial objects.
Once cleaning is complete, a new map is automatically generated.
11. WOOD Eco Recovery Mode
If detected:
spawning grounds;
rare plants;
mollusks;
crayfish;
birds' nests,
robot automatically:
reduces power;
changes the route;
ceases operations in this sector.
12. WOOD Swarm Recovery
Several robots work together.
For example:
Scout:
looking for pollution.
Recovery:
extracts material.
Cargo Platform:
takes out.
Restore:
restores the bottom.
Service:
changes tools.
The entire process is coordinated by DREVO AI.
13. DREVO Sediment Factory
The removed sludge is considered a resource.
After analysis it can be used:
for the production of soil mixtures;
restoration of quarries;
reclamation;
production of building materials;
obtaining biochar after processing the organic fraction;
extraction of minerals.
Before use, an environmental assessment is carried out to determine the content of pollutants.
14. WOOD Smart Dock
Coastal station automatically:
accepts material;
sorts;
changes the container;
washes equipment;
charges batteries;
replaces tools.
Service time:
10–20 minutes.
15. DREVO Digital River Passport
After each operation, the digital passport of the site is updated.
Added:
new bottom map;
volume of extracted material;
found objects;
water quality;
photographs;
recovery results;
DREVO AI recommendations.
16. DREVO Eco Bubble Shield (new solution)
A ring of fine air bubbles is created around the working area.
Advantages:
localizes suspended matter;
reduces the spread of turbidity;
improves water aeration;
helps keep light contaminants in the work area for later collection.
17. DREVO Selective Sediment Knife (new solution)
A narrow, adjustable cutting knife is installed in front of the suction head.
He:
carefully separates the top contaminated layer;
practically does not affect the underlying natural sediments;
reduces the amount of suspended matter raised;
increases cleaning accuracy.
18. DREVO Sediment Dewatering Pods (new solution)
On board are placed modular containers with geotextile bags for sludge dewatering.
Advantages:
the weight of the transported material is reduced;
the number of flights is decreasing;
purified water after quality control can be returned to the reservoir;
subsequent processing is simplified.
19. DREVO Adaptive Current Control (new solution)
During operation, the robot uses controlled flow deflectors and low-power water jets.
This allows:
direct the suspension to the suction zone;
reduce its spread downstream;
increase the efficiency of collecting small particles.
20. DREVO Underwater Drone Dock (new solution)
On board there is a mini-dock for autonomous underwater drones.
They perform:
inspection under bridges;
search for objects in hard-to-reach places;
pipe inspection;
detailed mapping before main cleaning.
The main platform remains in the safe area and only performs lifting and processing of material.
New generation concept
The combination of these decisions transformsWOOD River Rover Recoveryfrom a regular bottom cleaning machineintelligent robotic ecosystem for river restoration, where each operation is aimed at:
minimal interference with natural processes;
maximum conservation of biodiversity;
extraction and reuse of valuable resources;
creation of a digital model of the bottom before and after work;
Continuous improvement of algorithms thanks to artificial intelligence and data accumulation.
