Tutorial: Underwater Robots (ROVs) in RobotOps

1. Introduction & Overview

What are Underwater Robots (ROVs)?

• ROVs (Remotely Operated Vehicles) are tethered underwater robots controlled by operators from the surface.
• They are primarily used for:
  • Deep-sea exploration
  • Offshore oil & gas maintenance
  • Underwater infrastructure inspection
  • Search and rescue missions
• In RobotOps (Robotics Operations), ROVs are operational assets that require monitoring, automation, logging, CI/CD pipelines, and remote observability for effective lifecycle management.

History or Background

• 1950s – First tethered ROV prototypes developed for military mine clearance.
• 1960s–70s – ROVs were used by the U.S. Navy for submarine recovery.
• 1980s–90s – Commercial adoption in offshore oil & gas for pipeline inspection.
• 2000s – Miniaturized ROVs became accessible for scientific research and underwater archaeology.
• Today – Advanced AI, IoT, cloud integration, and RobotOps pipelines make ROVs smarter, autonomous, and data-driven.

Why are ROVs Relevant in RobotOps?

• RobotOps ensures that robots (including underwater ROVs) are:
  • Continuously monitored
  • Automatically updated with new software
  • Secured against cyber threats
  • Efficiently logged and auditable
• With CI/CD pipelines, ROVs can get real-time firmware updates, automated testing, and seamless integration with cloud monitoring dashboards.

2. Core Concepts & Terminology

Term	Definition	Relevance in RobotOps
ROV (Remotely Operated Vehicle)	A tethered underwater robot controlled from the surface.	Primary asset under RobotOps.
AUV (Autonomous Underwater Vehicle)	An autonomous robot without tethers.	Alternative to ROVs, less controlled but more independent.
Tether	Cable that connects ROV to surface ship.	Used for power & data transfer.
Manipulator Arm	Robotic arm used for handling underwater objects.	Needs RobotOps monitoring for wear & tear.
Thrusters	Propulsion units for movement.	Requires telemetry monitoring.
RobotOps Pipeline	CI/CD + Monitoring lifecycle for robots.	Ensures smooth operations & updates.

How ROVs Fit into the RobotOps Lifecycle

1. Build Phase – Develop and test ROV control software.
2. CI/CD Deployment – Push updates to ROV systems remotely.
3. Monitoring & Telemetry – Real-time logging of depth, pressure, and motor performance.
4. Security & Compliance – Ensure encrypted communication and compliance with maritime laws.
5. Incident Response – Automated rollback if new firmware update fails.

3. Architecture & How It Works

Core Components of an ROV

• Mechanical Systems: Thrusters, manipulator arms, frame.
• Control Systems: Joysticks, surface computers, AI-assisted navigation.
• Sensors: Cameras, sonar, depth sensors, temperature probes.
• Tether System: Power + data cable to surface.
• Cloud/RobotOps Layer: Telemetry collection, CI/CD pipeline, logs, monitoring, anomaly detection.

Internal Workflow

1. Operator inputs command via joystick / cloud API.
2. Commands travel through tether → onboard ROV controller.
3. Sensors collect real-time data and send it back to the surface.
4. Data is pushed to cloud RobotOps platform for monitoring.
5. CI/CD pipelines update ROV firmware and control software automatically.

4. Installation & Getting Started

Prerequisites

• Basic ROV kit (e.g., BlueROV2)
• Surface control station (laptop with Ubuntu/ROS installed)
• Internet connection for RobotOps integration
• Docker + Git for CI/CD

Step-by-Step Setup

1. Install Required Software

sudo apt update
sudo apt install docker docker-compose git

2. Clone ROV Control Software

git clone https://github.com/bluerobotics/rov-software.git
cd rov-software

3. Run in Docker (ROS-based)

docker-compose up -d

4. Connect to ROV

• Plug tether into Ethernet port.
• Run ifconfig to check network connectivity.

5. Integrate with Cloud Monitoring

• Configure Prometheus exporter for telemetry:

scrape_configs:
  - job_name: 'rov'
    static_configs:
      - targets: ['192.168.2.2:9100']
