Onboard quadrocopter failsafe: flight after actuator failure

This video presents the latest iteration of  IDSC's Flying Machine Arena failsafe algorithm (previous post here). In this video there's a pilot flying the quadrocopter while the algorithm is executed on the quadrocopter's onboard micro-controller. The only sensors required are the quadrocopter's angular rate gyroscopes.

You can read more on the description of the video ( https://www.youtube.com/watch?v=ek0FrCaogcs

Proof that it can be done without the vicon system is fantastic!  Very nice!

Very cool

Brilliant!  Want it.

we need it for arducopter!!!!!!!

This is absolute genius! To see it functioning without the motion capture, in a real world situation is remarkable! This should be added to the code as soon as possible!! I wonder if the effect works on larger quadcopters with gimbals or other payloads. How does the COG affect the algorithm?

The algo prolly has a pid system for angular movement, which complements the straight movement currently used by multicopters now.

Please release the code as free software for a safe drone world.

I would settle for a complete description of the algorithm.. but a reference implementation would be a LOT nicer..

I will call this either the 'scrambled egg recovery' or 'blender rescue' technique; perfectly suitable as compared to

destruction of the aircraft and/or payload.

Well done, Bravo!

Take a look and don't forget to also read the comments with direct replies from Mark W. Mueller, the main researcher for this project ;)
