Autonomous High-Altitude Work Robot TowerClimb Deployed: Unmanned Inspection on 300-Meter Wind Turbine Towers

Autonomous High-Altitude Work Robot TowerClimb Deployed

On October 8, 2030, Danish wind energy company Vestas announced the full deployment of TowerClimb autonomous high-altitude inspection robots across 50 five-megawatt wind turbines at its Horns Rev 3 wind farm in the North Sea. TowerClimb can autonomously climb wind turbine tower exteriors (heights of approximately 100 to 300 meters) to perform blade surface inspection, bolt torque checks, and anti-corrosion coating repair.

Wind power operations and maintenance is high-risk work — technicians must operate in narrow spaces at heights of hundreds of meters, often affected by strong winds and low temperatures. TowerClimb's design goal is to free humans from these hazardous environments.

TowerClimb uses a wheeled magnetic adhesion climbing mechanism that can move up and down steel tower exteriors at 0.5 meters per second. The robot is equipped with high-resolution cameras, ultrasonic flaw detectors, and torque wrenches, enabling it to autonomously complete over 90% of routine inspection tasks.

Vestas Operations Director Henrik Andersen said: "TowerClimb reduces inspection time per turbine from 8 hours (including personnel climbing and safety preparation) to 3 hours, and is not limited by weather — it can work as long as wind speeds do not exceed 25 m/s."

TowerClimb was developed by Norwegian robotics company ScoutDI, with each unit priced at approximately 250,000 euros. Vestas's total deployment cost for 50 units is about 12.5 million euros, but it is expected to save approximately 8 million euros annually in operations and maintenance costs, primarily from reduced labor and downtime.

ScoutDI plans to expand TowerClimb's applications to communication towers, bridges, and high-rise building exterior inspections by 2031.
