Robotic inspectors developed to fix wind farms

Fully autonomous robots that are able to inspect damaged wind farms have been developed by Scots scientists. Unlike most drones, they don't require a human operator and could end the need for technicians to abseil down turbines to carry out repairs. The multi-million pound project is showing how the bots can walk, dive, fly and even think for themselves. They're being developed by Orca - the Offshore Robotics for Certification of Assets hub. The hub bills itself as the largest academic centre of its kind in the world and is led from Heriot-Watt and Edinburgh universities through its Centre for Robotics.
