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
- Build Phase – Develop and test ROV control software.
- CI/CD Deployment – Push updates to ROV systems remotely.
- Monitoring & Telemetry – Real-time logging of depth, pressure, and motor performance.
- Security & Compliance – Ensure encrypted communication and compliance with maritime laws.
- 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
- Operator inputs command via joystick / cloud API.
- Commands travel through tether → onboard ROV controller.
- Sensors collect real-time data and send it back to the surface.
- Data is pushed to cloud RobotOps platform for monitoring.
- CI/CD pipelines update ROV firmware and control software automatically.

- Surface control station (laptop with Ubuntu/ROS installed)
- Internet connection for RobotOps integration
- Docker + Git for CI/CD
Step-by-Step Setup
- 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.
