Perceptual Robotics Raises £4M+ to Scale AI-Powered Wind Turbine Inspections

The round was announced in July 2026 . Perceptual Robotics has now raised a total of approximately $7.2–$8.87 million across multiple rounds, according to different funding trackers .

How the Dhalion System Works

The company's core product is the Dhalion system, which uses autonomous drones and artificial intelligence to fully automate the wind turbine inspection process . Here is how it works:

• A minimally trained operator launches the drone using a tablet; the drone flies autonomously and captures high-resolution imagery of the turbine blades, tower, and other components .
• After landing, a cloud-based AI system automatically processes the images to detect and classify damage — such as lightning strikes, cracks, erosion, and delamination — within minutes .
• The system delivers comprehensive inspection reports within 48 hours, including repair prioritization and cost-estimation tools .
• An AI metric called the Repair Now Ratio predicts how damages will affect Annual Energy Production over time, helping operators decide which repairs to tackle first .

The company offers two drone products: DOT, a fully autonomous all-in-one inspection drone, and EVE, a portable mini-drone for rapid, on-demand inspections .

The Dhalion software also runs on DJI M300, M350, and Mavic 3 Enterprise drones, making it accessible to operators who already own those platforms .

Proven Accuracy and Scale

A three-year Innovate UK R&D project involving Perceptual Robotics, the University of Bristol, and DNV found that the fully automated system had a 14% improvement in fault detection accuracy compared to traditional manual methods . The same project was also the first to fully automate the image-processing step, not just the image capture .

The company has now inspected more than 250 onshore wind turbines using its Dhalion system . One customer recently completed over 150 turbine inspections across the UK in a single campaign using Dhalion .

Global Customer Base

Perceptual Robotics' drone and AI inspection tools are deployed across multiple regions :

• Europe — including the UK, Sweden, Germany, and other European markets
• North America — the company launched operations here following its 2023 pre-Series A round
• Asia Pacific — expanded via a strategic partnership with the K2 Energy Group, based in Singapore

The company also entered Latin America and Jamaica in 2025 .

Product Developments Driven by User Collaboration

The company explicitly states that its product evolution has been driven by listening to operators, asset managers, and maintenance teams . Specific user-led developments include:

• Faster turnaround times — operators who needed answers quickly, not weeks later, led to the 48-hour report delivery target
• Clearer decision-making — asset managers balancing cost, downtime, and risk pushed for clearer damage classification and prioritization instead of more raw data
• Offshore services — user demand for comprehensive offshore inspection capabilities led to a dedicated offshore service launch in 2024

Plans for the New Capital

Perceptual Robotics intends to use the £4 million+ funding to :

• Scale its AI-powered wind inspection platform globally
• Expand into new international markets, particularly offshore wind
• Enhance offshore capabilities with dedicated services and systems
• Support ongoing product development of the Dhalion, DOT, and EVE systems
• Accelerate commercialization of its autonomous inspection technology

The company's long-term goal is to become "the #1 solution for wind farm owners and service providers taking control of their inspection and data" .
