What Perceptual Robotics does

Perceptual Robotics is a Bristol, UK-based private company founded in 2016 as a spin-out from the University of Bristol, specializing in AI-powered autonomous drone inspections of wind turbine blades. The company operates the Dhalion platform, which combines two drone systems — Dot (built on DJI Matrice 300/350) for detailed inspections and Eve (built on DJI Matrice 4/Mavic 3) for compact, portable deployments — with proprietary AI algorithms for blade damage detection and classification at 1–3 pixels/mm resolution, delivering inspection reports within 48 hours under the standardized Dhalion Guidelines framework.

The company serves five primary customer segments: wind farm owners and operators, wind energy OEMs, independent service providers (ISPs), drone companies, and wind farm asset managers. Named customers include Fred.Olsen Renewables, wpd windmanager, Galventus, FullCircle Wind Services, Skyforest, Wigton, Rotortech, Renewable Field Services, Kompact Renewables, and Assettech, with operations spanning 18 countries including the UK, Greece, Spain, Italy, Sweden, Finland, Latvia, Romania, Croatia, India, Norway, Portugal, Argentina, and Jamaica. The company maintains a wholly-owned subsidiary, Perceptual Robotics Hellas SMPC, in Athens, Greece.

Perceptual Robotics generates revenue through three streams: sale of Dhalion hardware systems (Dot and Eve drones), professional inspection services delivered by in-house UAV pilots, and AI-driven data processing and analysis services. The company is venture capital-backed, with cumulative disclosed funding of approximately £2.7M+ led by OnePlanetCapital in 2023, and follow-on rounds from Susten (2023), Brookstreet Equity Partners, and Loggerhead Ventures (2026). It holds ISO 9001 and ISO 27001 certifications and maintains strategic technology partnerships with L3Harris Technologies (offshore wind), DNV (inspection standards), DJI (drone platforms), VulcanUAV (offshore inspection), and the University of Bristol Visual Information Lab (R&D). Leadership consists of co-founders Kostas Karachalios (CEO), Dimitris Nikolaidis (COO), and Kevin Driscoll-Lind (CTO).
