Quadcopter failsafe algorithm

Dear friends,

Although only five months young, dronologista blog has grown and needs a new attire.

As of 1st of September, dronologista.com moves to a new hosting, new address and slightly changes the appearance . Content will remain the same, and dronologista will continue to provide information about non-military drones only.


Safety is of paramount importance when it comes to flying objects. Every development in the safety area, whether it is hardware, software or process related is priceless.

One of the recent achievements is a quadcopter safety algorithm that prevents a crash in case of propeller failure.

When a propeller fails, this fail safe routine will recover drone from stall, and keep it in more or less upright position. What is interesting is that the fail safe controller uses existing hardware that is already available on a standard quadcopter, and that it can be implemented as an algorithmic upgrade to existing systems.

Team around Prof. Raffaello D’Andrea designed a system that is likely to become a standard feature on future multirotor designs.

Dronologista hopes that this system can prevent scenes like this from happening.
