The interior of a wind turbine blade is a world of its own—a dark, narrow, and complex tunnel where even the smallest structural anomaly can lead to catastrophic failure. Traditionally, inspecting these “dark zones” meant sending technicians into confined spaces with limited visibility and high physical risk.
At Onna Robotics, we are moving beyond traditional methods by deploying advanced, autonomous technology designed to see what the human eye cannot.
1. Navigating the Dark: 4×4 Autonomy and SLAM Technology
Our specialized Internal Crawler is not just a camera on wheels; it is a high-tech explorer designed for the most challenging confined spaces.
-
Superior Mobility: Equipped with a rugged 4×4 drivetrain, our robot navigates the steep inclines and complex geometries of the blade’s interior with ease.
-
Autonomous Intelligence: Utilizing SLAM (Simultaneous Localization and Mapping) and Lidar depth cameras, the crawler maps the internal structure in real-time. This allows for precise positioning, ensuring every inch of the bulkhead and bonding lines are accounted for without human intervention.
2. The AI Advantage: From Images to Insights
Data is only valuable if it is actionable. Our robots utilize Machine Learning and AI-driven Crack Detection to analyze the internal composite structure.
-
Structural Precision: Our algorithms are trained to identify bonding failures, delamination, and resin-starved areas that are often invisible to the naked eye.
-
Objective Reporting: By automating the detection process, we remove human subjectivity, providing consistent and repeatable data that aligns with Digital Twin standards.
3. A New Perspective: The VR Inspection Experience
We believe that our clients should have total transparency. Through our Lidar-generated 3D maps and 360-degree imaging, we offer a Virtual Reality (VR) Inspection experience.
-
Virtual Walkthroughs: From the safety of your office, you can put on a VR headset and virtually “walk” through the interior of your turbine blade. This immersive experience allows engineers to inspect critical points of interest as if they were physically inside the blade, but without any of the HSE risks.
4. The Onna Web Portal: Your Data, Centralized
The days of sifting through massive PDF reports are over. All data captured by our internal crawlers is uploaded to the Onna Web Portal.
-
Real-time Access: View high-resolution imagery, 3D maps, and AI-detected fault logs in a centralized dashboard.
-
Predictive Maintenance: Track the health of your blades over time and plan repairs before a minor issue turns into a major shutdown.
5. Proven Innovation, Expert Leadership
Founded in 2021, Onna Robotics is a deep-tech company backed by KOSGEB R&D/P&D and TÜBİTAK 1507 grants. Our journey of innovation has been recognized globally, most recently as a 2025 ITU Big Bang Finalist.
Our strength lies in our multi-disciplinary team, led by four founders with a combined century of experience at global giants like Microsoft, Cisco, Vestel, and Koç. We don’t just build robots; we build certified, reliable solutions for the world’s most critical energy infrastructure.
