The material of wind energy converters must withstand intense forces. Are rotor blades damaged? A new robot inspects wind energy converters more precisely than a human ever could. It detects the minutest damage – even below the surface. It appears reliably and appears alone. Nimbly and quickly, it pulls itself up a rope meter for meter until it reaches a wind energy converter’s giant rotor blades. Then it goes to work. It thoroughly inspects every centimeter of the rotor blades’ surface. (source: fraunhofer.de)
