Underwater Robot Fleet

What Are Underwater Robot Fleets?

Autonomous Underwater Vehicles (AUVs) are robots that explore the ocean without human operators. They map the seafloor, monitor marine life, inspect infrastructure, and collect data in environments too deep or dangerous for human divers. By deploying multiple robots as a coordinated fleet, we can survey vast ocean areas far more efficiently than a single vehicle.

Why does this matter? Over 80% of the ocean floor remains unmapped. Coordinated AUV fleets using sonar, cameras, and acoustic communication can map terrain, discover new species, monitor climate change effects, and inspect critical underwater infrastructure — all autonomously.

📖 Deep Dive

Analogy 1

Think of an AUV fleet like a team of bloodhounds searching a dark forest — each robot independently covers ground, communicating finds to the group through acoustic 'barks' in the water, building a shared map of the unexplored territory.

Analogy 2

Coordinating underwater robots is like managing a group of scuba divers in zero-visibility water — they can't see each other, can only communicate through slow sound signals, and must avoid collisions while collectively completing the survey.

🎯 Simulator Tips

Beginner

Deploy a small fleet and watch acoustic communication coordinate exploration.

Intermediate

Add ocean currents and murky conditions to test fleet adaptation.

Expert

Design a multi-depth fleet with heterogeneous robots for mapping, sampling, and relay.

📚 Glossary

AUV

Autonomous Underwater Vehicle — self-propelled robot navigating and collecting data without a tether.

ROV

Remotely Operated Vehicle — tethered underwater robot controlled by a human operator from the surface.

Acoustic Communication

Underwater data transmission using sound waves (1-100 kbps) since radio waves barely penetrate water.

SLAM Underwater

Simultaneous Localization and Mapping using sonar in GPS-denied underwater environments.

Multi-beam Sonar

Acoustic sensor creating detailed 3D seafloor maps using hundreds of simultaneous sound beams.

Biofouling

Growth of marine organisms on robot surfaces degrading sensors and increasing drag over time.

Pressure Hull

Sealed structure protecting electronics from crushing ocean pressure (1 atm per 10m depth).

Buoyancy Engine

Mechanism changing vehicle density to ascend/descend without propellers, conserving energy.

Cooperative Mapping

Multiple AUVs collaboratively surveying an area, sharing data to build unified maps.

Deep-Sea Mining Robot

Specialized underwater vehicle designed to collect mineral deposits from the ocean floor.
