Quadcopter Recovers After Losing a Propeller
Mark Mueller · Demo · 1 min · 2013 · YouTube title: Quadrocopter failsafe algorithm: recovery after propeller loss
Why it's here
HN cites it to show that a quadcopter can keep flying after losing a rotor, though under ideal lab conditions.
What it covers
An ETH Zurich lab demonstration of a failsafe algorithm that lets a quadrocopter detect the loss of a propeller and recover, returning to its original position.
