Researchers from the Robotics and Perception Group from the University of Zurich, developed a new technology that allows a quadrotor to automatically recover and stabilize from any initial condition without relying on external infrastructure like GPS. The technology allows the quadrotor system to be used safely both indoors and out, to recover stable flight after a GPS loss or system failure. And because the recovery is so quick, it even works to recover flight after an aggressive throw, allowing you to launch a quadrotor simply by tossing it in the air like a baseball.

  • Lots of potential here!

  • Good stuff!!

  • I think it's already integrated in almost controller ...

    Proportionnal Integral Derivative...

    There is no magic formula needed to accomplish the same action

  • Where is that paper? At their website?
  • @Waladi - thoroughly read the research papers first, then write the code...

  • Will this technology be available for public ?

  • I think I'll need this to drop quads from flying fixed wings... ;-)

  • Dr. Da IDE Scaramuzza, Dr. Roland Siegwart, Dr. Samir Bouabdallah, and others at the Swiss Federal Institute of Technology have done incredible work in this field and every other aspect of this technology (especially quad rotors, etc.) since at least 2004. There is a wealth of information available on all the web resources published by that group. Thanks for all the great work!
  • I totally admire your work!

  • Really nice development guys, should be very useful.

    It seems we are going to be seeing a lot more visual odometry stuff coming from your group.

    Best regards,
