Aerones is an innovative company that has developed robotic technology for wind turbine blade maintenance services, such as: • Conductivity measurements and trouble-shooting; • Drainage hole cleaning; • External inspection of the wind turbine blades; • Internal inspection of the blades; • Blade & Tower cleaning; • Coating application on the leading edges; • Leading-edge repair. The technology in use is controlled remotely. In addition, it is compact and easily transportable. Aerones is the first company in the world to provide the services using robotic technology: the maintenance process does not require technicians to work in dangerous heights, and thus is much safer, more efficient, and the downtime of the turbines is decreased significantly.
