Your technicians cannot physically inspect a 900°C boiler tube while it is running. They cannot walk inside an energized transformer bay. They cannot crawl through a confined cooling duct at 2 AM without a confined-space permit and a two-person crew. ROS2-powered inspection robots can — and when those robots pipe real-time defect data directly into OXmaint CMMS, the entire gap between detection and corrective action collapses to minutes, not weeks. Sign in to OXmaint and connect your robotic inspection fleet to automated work order generation today.

ROS1 end-of-life date — ROS2 Jazzy is now the only supported industrial standard
Ready to Deploy
OXmaint Is the CMMS Built for ROS2 Robotic Inspection Workflows
Every defect a ROS2 robot detects is only valuable if a technician receives a work order and acts on it. OXmaint closes that loop — turning robot sensor streams into prioritized, documented, compliance-ready maintenance actions across your entire power plant.
What ROS2 Brings to Power Plant Inspection
ROS2 (Robot Operating System 2) is the open-source industrial middleware standard that replaced ROS1 in May 2025. It solves the core limitations of its predecessor — real-time determinism, multi-robot coordination, and secure DDS communication — making it the only viable platform for safety-critical industrial inspection environments.
ROS2 Jazzy
Real-Time DDS Middleware
Data Distribution Service (DDS) replaces ROS1's unreliable pub-sub model with deterministic, low-latency message delivery. In a power plant, this means a thermal anomaly detected at a turbine bearing is published and received in milliseconds — not seconds — triggering an OXmaint alert before the anomaly escalates.
Nav2 Stack
Autonomous Navigation
ROS2's Nav2 framework uses SLAM Toolbox and AMCL to build real-time maps of GPS-denied environments and navigate patrol routes autonomously. Inspection robots build a live 2D or 3D map of your turbine hall on first deployment and execute repeatable patrol missions every shift without operator intervention.
robot_localization
Multi-Sensor Fusion
The ROS2 robot_localization package fuses LiDAR, IMU, and wheel encoder data via Extended Kalman Filtering to achieve stable, drift-resistant pose estimation. In dynamic industrial environments with vibration and electromagnetic interference, this fusion provides centimeter-level positional accuracy during active inspections.
ros2_control
Hardware Abstraction
ros2_control provides a unified interface for managing diverse hardware — ground robots, crawlers, and aerial drones — through a single software layer. Power plants can deploy heterogeneous robot fleets with different physical configurations, all coordinated under one ROS2 namespace feeding into OXmaint.
Security Architecture
SROS2 Encrypted Comms
SROS2 adds hardware-level encryption and authentication to all robot communications. This satisfies NERC CIP cybersecurity requirements for networked devices in power plant control environments, preventing unauthorized access to robot control channels or sensitive sensor feeds.
Multi-Robot Coordination
Fleet-Scale Deployment
ROS2 eliminates the single-point-of-failure architecture of ROS1. Dozens of inspection robots across a 500-acre plant can operate in parallel, each handling a designated zone, while OXmaint tracks global maintenance status and prevents duplicate work orders from competing robot alerts on the same asset.

ROS2 Inspection in Action: Power Plant Use Cases
Zone A
Boiler and HRSG Inspection
Ground robots equipped with thermal cameras and UT sensors navigate tube sheets and fireside surfaces during outages. ROS2 SLAM maps internal geometry against design drawings, flagging tube thinning below OEM-specified minimum wall thickness. OXmaint receives an immediate work order with tube row coordinates, ultrasonic reading, and recommended repair action.
Tube failures caught avg. 6–8 weeks before visual detection
Zone B
Substation and Transformer Patrol
Wheeled inspection robots patrol live substation bays 24/7, using thermal imaging to detect hot joints in bus connections and acoustic sensors to identify partial discharge in transformer windings. SROS2 encrypted channels satisfy NERC CIP requirements for networked devices in the control environment. Every anomaly becomes a dated, geo-coded OXmaint work order.
Partial discharge detected at 0.5 pC sensitivity — 40× better than annual manual scan
Zone C
Gas Turbine Compressor Path
Blade inspection robots use RGB-D imaging and structured light scanning to detect micro-cracking, leading-edge erosion, and foreign object damage between combustion inspections. ROS2 Nav2 navigates compressor inlet geometry autonomously without scaffolding or manual entry. OXmaint logs every scan with blade row coordinates for OEM-traceable maintenance records.
Avoids $2.4M+ compressor blade replacement from undetected FOD damage
Zone D
Cooling Tower and Condenser Survey
Aerial and crawler robots survey cooling tower fill condition, drift eliminator integrity, and condenser tube bundles using thermal and visual fusion. Rising approach temperature readings correlated with robot-detected tube fouling generate a single, evidence-rich OXmaint work order — with photos, approach delta, and cleaning recommendation — instead of a vague reactive complaint.
Approach temperature deviation caught at 1.5°F — before efficiency loss becomes visible
What Plants Gain When ROS2 Robots Feed OXmaint
We deployed a ROS2 ground robot for our 1,100°C boiler tube inspection during our planned outage. The robot flagged seventeen tube sections with wall thickness below 4mm — none of which appeared on our previous manual inspection report from six months earlier. Those tubes would have failed mid-season. Every finding came through as a geo-coded work order in OXmaint before our outage crew meeting the next morning. That single deployment justified the entire robotics program budget.

Frequently Asked Questions
ROS2 (Robot Operating System 2) is the open-source middleware standard for industrial robots, replacing ROS1 after its May 2025 end-of-life. For power plants, ROS2 matters because it introduces real-time DDS communication for deterministic, low-latency sensor data delivery, SROS2 encryption satisfying NERC CIP cybersecurity requirements, multi-robot coordination for fleet-scale inspection programs, and a hardware abstraction layer that lets you deploy diverse robot types — ground crawlers, aerial drones, and pipe inspection robots — under one software stack feeding into OXmaint. Sign up free to see how OXmaint integrates with ROS2 robot fleets.
ROS2 Jazzy Jalisco is the current long-term support (LTS) release of ROS2, making it the industrial standard for production deployments. With ROS1 officially reaching end-of-life in May 2025, all new industrial robotic inspection programs should be built on ROS2 Jazzy. It includes updated Nav2 navigation stack capabilities, improved SLAM Toolbox integration, enhanced DDS middleware performance, and the full suite of sensor fusion packages including robot_localization and ros2_control needed for power plant inspection environments.
ROS2 inspection robots navigate GPS-denied power plant environments using SLAM (Simultaneous Localization and Mapping). The SLAM Toolbox package processes 360° LiDAR data to build a real-time 2D or 3D map of the environment while simultaneously tracking the robot's position within it. The robot_localization package fuses LiDAR, IMU, and wheel encoder data via Extended Kalman Filter to prevent positional drift caused by vibration and electromagnetic interference common in turbine halls and switchyards. On first deployment, the robot builds its map; on subsequent patrols, AMCL (Adaptive Monte Carlo Localization) maintains centimeter-accurate positioning against the saved map.
ROS2 defect detection events are published to a ROS2 topic via DDS middleware. A bridge node translates these events into REST API calls to OXmaint, carrying the asset ID, defect classification, severity score, GPS coordinates, and attached sensor images. OXmaint receives this data and automatically generates a prioritized work order with all fields pre-populated — no manual entry required. The integration supports both real-time event-driven triggers (immediate defect alerts) and scheduled batch uploads (end-of-patrol inspection summaries). Book a demo to see the live integration architecture.
OXmaint's ROS2 integration is robot-agnostic — any robot running a ROS2 node stack can feed data into the platform. This includes ground inspection robots (Boston Dynamics Spot, Clearpath Robotics Husky), aerial drones with ROS2 stacks (for cooling tower and rooftop inspection), confined-space crawlers for boiler and duct inspection, rail-guided robots for substation patrol, and custom-built pipe inspection robots using ros2_control hardware abstraction. The OXmaint integration layer receives standardized ROS2 topic data regardless of the underlying robot hardware.
Yes, when properly configured. SROS2 provides hardware-level encryption and authentication for all robot communications, satisfying NERC CIP requirements for networked devices in power plant control environments. OSHA confined-space entry requirements are addressed by replacing human entry with robotic inspection in permit-required confined spaces — with OXmaint logging every robot inspection as a documented alternative to human entry with timestamped records. Every ROS2-triggered OXmaint work order produces a digitally signed, auditable record satisfying NERC GADS documentation and insurance audit requirements.
Your Power Plant Has Blind Spots. ROS2 Robots and OXmaint Eliminate Them.
