WOOD River Rover Recovery

WOOD River Rover Recovery

An autonomous robotic platform for bottom cleaning, bogwood extraction, and valuable resource search

Concept

DREVO River Rover Recovery (RRR-Recovery)— a heavy autonomous underwater and surface robotic platform designed for environmental cleanup of the bottoms of rivers, lakes and reservoirs while simultaneously searching, sorting and retrieving useful materials.

UnlikeRiver Rover Clean, which works primarily with surface debris and coastal areas,River Rover Recoveryspecializes in working directly on the bottom of reservoirs.

The platform's main objective is to remove hazardous contaminants, clean up bottom sediments, and return valuable materials to economic circulation.

The main principle:

Each seabed cleanup should simultaneously improve the environment and return resources to the economy.

Main tasks

The platform is designed for:

cleaning of river bottoms;

removal of contaminated sludge;

search for metal objects;

search for historical objects;

extraction of bog wood;

search for sunken equipment;

extraction of fishing nets;

removal of cables and scrap metal;

cleaning around bridges;

restoration of the natural topography of the bottom.

Application areas

Used by:

rivers;

mountain rivers;

lakes;

reservoirs;

channels;

port;

berths;

deltas;

lagoons;

swampy water bodies.

Architecture

The complex consists of two parts.

Surface platform

Catamaran.

It contains:

power point;

battery;

pumps;

containers;

manipulator;

winch;

filtration system;

sorting line.

Underwater module

Works under the platform.

Equipped with:

cameras;

sonar;

manipulators;

hydraulic suction module;

magnetic separator;

ground scanner.

Main dimensions

Bottom research system

Used:

Multibeam echo sounder

Creates a highly accurate map of the bottom.

Side sonar

Allows you to see:

wood;

boulders;

technology;

pipes;

designs.

Magnetometer

Defines:

iron;

steel;

cast iron;

sunken cars;

ammunition (with subsequent transfer of information to specialized services).

Electromagnetic scanner

Allows you to detect metal objects under a layer of bottom sediments.

Underwater LiDAR

For work at shallow depths and in clear water.

Cleaning the bottom

Several technologies are used.

Vacuum sludge collector

Raises only the top contaminated layer.

The sampling depth is adjusted automatically.

Bottom-mounted robot vacuum cleaner

Removes:

leaves;

plastic;

glass;

small debris.

Does not destroy the natural bottom.

Auger pick-up

Used by:

for sand;

gravel;

contaminated sludge.

Hydroejector

Creates local loosening of bottom sediments before suction.

Sludge filtration

The sludge enters the platform.

Next comes:

water separation;

separation of stones;

wood separation;

magnetic separation;

separation of non-ferrous metals;

selection of small objects;

dehydration.

Purified water is returned back only after quality control.

Metal detecting system

The combination used is:

magnetometer;

induction metal detector;

computer vision;

artificial intelligence.

The following are detected:

coins;

tools;

weapon;

pipes;

reinforcement;

cars;

bicycles;

boat motors;

scrap metal.

Search for precious metals

The additional module is capable of highlighting:

gold;

silver;

platinum;

rare minerals.

Used:

gateway concentrators;

vibrating tables;

hydrocyclones;

centrifugal concentrators.

Application depends on the legislation of a particular country and requires appropriate permits.

Search for bog wood

One of the most promising areas.

The system determines:

form;

density;

wood species;

dimensions;

depth of occurrence.

After detection:

the wood is carefully released;

fixed with straps;

lifted by a manipulator or floating lifting cylinders.

Processing of bog wood

A separate line is being created on the shore.

In progress:

cleaning;

slow drying;

scanning;

digital passport;

sorting.

Usage:

furniture;

musical instruments;

interior;

art products;

restoration.

Manipulators

The platform is equipped with:

With a heavy crane

Load capacity:

1–3 t.

With an underwater hand

Used by:

for precise operations;

extraction of small objects;

sampling.

Sorting system

All materials are automatically separated.

Categories:

wood;

stone;

plastic;

glass;

iron;

non-ferrous metals;

organics;

open;

hazardous waste.

Artificial intelligence

WOOD AI

Defines:

object type;

value;

extraction method;

the need for operator participation;

optimal cleaning route.

Environmental safety

During operation the following are monitored:

turbidity;

oxygen content;

flow speed;

noise level;

impact on fish;

impact on plants.

If the permissible parameters are exceeded, the system automatically reduces the intensity of work or stops it.

Works in conjunction with other platforms

River Rover Scout

Transmits a pollution map.

River Rover Clean

Cleans the surface.

River Rover Restore

Restores the bottom after cleaning.

River Cargo Platform

Takes out materials.

River Rover Service

Maintains equipment.

TREVO AeroSense Drone

Controls the process from above.

Integration

Works in conjunction with:

Living Mountain Observatory;

Mountain Digital Twin;

WOOD AI;

WOOD Clean Rivers;

DREVO Living Mountains.

Promising additional modules

Wood Scanner

Spectral analysis of bog wood and species determination.

Precious Metal Recovery

Extraction of fine heavy minerals from bottom sediments.

Archaeology Mode

Documentation of archaeological finds without automated extraction. Upon detection of potentially valuable objects, the system stops operations in the sector, records the coordinates, and transmits the information to authorized specialists.

Microplastic Recovery

Removal of microplastics from bottom sediments.

AI Sediment Mapper

Construction of a three-dimensional map of bottom sediments and prediction of pollution accumulation zones.

Preliminary specification

Project mission

WOOD River Rover Recoverycompletes the ecosystem of robotic platformsWOOD Clean Rivers, performing the most complex restoration work on benthic ecosystems. Its task is not only to remove pollution but also to restore valuable resources, such as bog wood and metals, while preserving the natural structure of the riverbed and minimizing the impact on the aquatic environment. Working in conjunction with the Scout, Clean, Restore, Service, and River Cargo Platforms, it creates a fully autonomous cycle of research, cleanup, restoration, and long-term monitoring of rivers and lakes.
