Our Waterways

A 4th-generation autonomous surface vehicle

ADDRAR IV is the latest iteration of an autonomous surface vehicle (ASV) built by the Engineering Senior Design team at Texas A&M University Corpus Christi. The system uses a Raspberry Pi 5 and onboard camera to detect floating debris in real time using computer vision.

Once debris is located, the robot autonomously navigates to the target and activates its collection mechanism — removing trash from the waterway without human intervention during the mission.

Core Capabilities

What ADDRAR Does

A purpose-built marine platform combining autonomous navigation, debris detection, and collection into a single deployable unit.

01

AI Debris Detection

Powered by a Raspberry Pi 5 and Pi Camera 3 Wide, the onboard AI vision system identifies floating debris in real time with a wide-angle field of view — distinguishing trash from natural objects on the water surface.

02

Mesh Collection System

Integrated mesh netting between the twin catamaran hulls captures floating debris as the vessel moves forward, retaining collected material without requiring manual retrieval mid-mission.

03

6-Propeller Drive

Six waterproof ring motors with propellers provide omnidirectional thrust, enabling precise maneuvering in tight spaces like marinas, harbors, and coastal inlets.

04

Dual Control Modes

Seamlessly switch between full AI autonomy and manual remote control, allowing operators to intervene for targeted collection or take over in complex scenarios.

05

Catamaran Stability

Twin-hull design provides excellent stability in varying water conditions while creating a natural channel for debris to flow into the collection mesh.

06

Waterproof Electronics

All electronics are housed in sealed enclosures with protected ESC controllers, ensuring reliable operation in marine conditions with splash and spray protection.

AI Vision System

How ADDRAR Sees & Hunts Debris

A trained computer vision model running on a Raspberry Pi 5 processes live video from the Pi Camera 3 Wide — detecting floating debris and autonomously steering the vessel toward it for collection.

Detection & Navigation Pipeline

01

Wide-Angle Capture

The Pi Camera 3 Wide captures a continuous video stream with a 120° field of view, scanning the water surface ahead and to both sides of the vessel.

02

Frame Processing on RPi 5

Each frame is fed into the Raspberry Pi 5 where the trained AI model runs inference in real time, analyzing every frame for debris objects against the water background.

03

Object Detection & Classification

The model draws bounding boxes around detected debris, classifying objects by type (plastic, wood, foam, mixed waste) and assigning a confidence score.

04

Autonomous Navigation

Detected debris coordinates are passed to the navigation system, which steers all six propellers to intercept and collect the target using proportional control.

IoT & Telemetry

Live Data & Monitoring

ADDRAR streams real-time telemetry data from its onboard sensors via IoT, giving operators full visibility into the vessel's status, environment, and mission progress.

GPS Positioning

Real-time GPS coordinates streamed continuously, tracking ADDRAR's patrol route and current position.

Battery & Motor Telemetry

Live voltage, current draw, motor RPM, and battery percentage — so operators know exactly when to recall the vessel.

Wireless Data Link

All sensor data transmitted wirelessly to the cloud, enabling remote monitoring from any device through the dashboard.

Live Video Feed

Stream real-time video from the Pi Camera 3 Wide directly to the dashboard — first-person view with live debris detection overlay.

Impact & Applications

Why ADDRAR Matters

Autonomous debris removal creates measurable impact across environmental, municipal, and maritime domains.

Environmental Protection

Continuous autonomous deployment removes plastic and waste before it sinks, breaks down, or harms marine life — operating in areas that are difficult or dangerous for human crews.

  • Reduces microplastic breakdown in waterways
  • Protects local marine ecosystems
  • Operates continuously without crew fatigue

City & Municipal Use

City stormwater systems and urban waterways accumulate debris rapidly after rain events. ADDRAR provides a cost-effective automated cleanup alternative to manual crew dispatch.

  • Automated stormwater drain cleanup
  • Lower operational cost than manual crews
  • Scalable across multiple waterways

Port & Marina Operations

Harbors and marinas require constant debris management to protect vessel hulls, propellers, and infrastructure. ADDRAR handles routine surface debris autonomously.

  • Protects vessel hulls from debris damage
  • Keeps marina channels clear
  • Reduces maintenance crew workload

A Deployable Solution for Coastal Texas

Developed and tested in the coastal environment of Corpus Christi — ADDRAR IV is purpose-built for the waterways it serves.

Live System Access

Robot Dashboard

Access the live control and monitoring interface. The dashboard runs on the robot's Raspberry Pi — only available when the robot is powered on and connected.

How Dashboard Access Works

The robot streams live video, telemetry, and accepts remote commands via a Cloudflare Tunnel hosted on the onboard Raspberry Pi 5. When the robot is on, the dashboard is live at dashboard.addrarlivevideo.com.

If the Pi is powered off or disconnected, the dashboard will simply be unavailable — the info site remains online regardless.

Note: Dashboard access is restricted to authorized operators. Select your vessel and enter the access password to proceed. Contact your team lead if you need credentials.
Secure Access Portal
Incorrect password or no vessel selected.
Opens dashboard.addrarlivevideo.com — if the Pi is offline, the page will fail to connect. This is expected.
