Rope Robotics is engaged in research, development and innovation activities involving key stakeholders in industry and universities. Most projects have received funding from European and Danish funding agencies.

Horizon 2020:  WindTTRo (Wind Turbine Repair Robot)

Rope Robotics has invented and patented the world’s first and so far, only, robot for performing all the phases of wind turbine blade leading edge maintenance and repair fast and reliably without having people performing hazardous tasks from ropes. The robot is able to do:

  • Surface area inspection and documentation
  • Sanding, grinding and filling of the area
  • Coating of the area
  • After repair inspection and documentation

Wind turbines provide an increasing amount of the European electricity, but the costs of operating and maintaining the turbine blades have been neglected so far.

Turbines have a life-time of 20-25 years, but the blade leading edge wears down in the harsh weather. The current method of repairing the leading edge by hand is inefficient, expensive, and involves hazardous working environments.

The overall success criterion of the project is to demonstrate to the market that the robot meets any demand set forth by wind turbine owners and manufacturers, and to document its performance and, thereby, become accepted as the new industry standard for wind turbine repair.

A primary driver for Rope Robotics’ business case is the extremely narrow bottleneck of manual repair performed by Rope Access Technicians. Repair is limited both by the lack of trained professionals and a lack of time windows to repair the wings during repair season.

The WindTTRo project has received funding from the European Union’s Horizon 2020 research and innovation program under the grant agreement No. 848747 and started in 2019.

EUDP: Offshore Wind Turbine Repair Robot

This project aims to overcome the additional development and logistical challenges associated with maintenance of offshore wind turbines and to demonstrate the functionality of the robot under real offshore conditions, carrying out full repairs of several turbines. The demonstration activities will focus on the most prominent issue, leading edge repair, but the robot will be developed to enable all repairs on the blades (and eventually other O&M tasks).

The project has received funding from the EUDP (Energiteknologisk Udviklings- og Demonstrationsprogram) and is joint effort with Siemens Gamesa Renewable Energy starting in 2019.


Markedsmodningsfonden: Robot-automated maintenance of wind turbines

The Rope Robot keeps performance of wind turbine blades up by inspecting and repairing wear and tear. Blades on wind turbine degrade in the weather and needs to be repaired every second year in worst cases. Maintenance today is done manually by rope access technicians.

The project has received funding from the Markedsmodningsfonden under the grant agreement 2017-11595 starting in 2017.


INNOBOOSTER:  Robotic solution to service of wind turbine blades

This project was funded by Innovationsfondens INNOBOOSTER program with grant number 7041-00135B. The project was successful completed in 2018.
