The gearing inside slipped and the brakes failed, the technicians couldn't repair it in time and had to evacuate when the wind got too high. The police setup a 400m safety perimeter so nobody got hurt.
Apparently, some of these turbines are supposed to rotate to be perpendicular to the wind if the wind got too high, and some have automatic folding blades.
The blades failed from the aerodynamic stress and centripetal force, and one sliced through the fiberglass tower.
Sorry it's not a robot but it's just so cool!
