Redundant stabilization systems for drones


Among the many advantages that have always contributed to the worldwide reputation of MikroKopter are the unequalled reliability and robustness of this "high-flying" electronics.

Users who have had the opportunity to try something else know well the sense of security that a pilot has when flying a MikroKopterhen flying a MikroKopter, because every day it starts and reacts in the same way to pilot's input.
Someone that flies a MikroKopter has always that reassuring feeling to remain the “master” of the aircraft in any situation, which is far from being the case with Asian imitations.

Because security and reliability have always been on the top of the agenda of the German manufacturer, and to push the limits even further, MikroKopter has developed a redundancy system.

More specifically, this consists in duplicating the critical elements of the drone, so that if a problem occurs to one of them, the standby system takes over allowing the pilot to bring the aircraft smoothly to the ground and land.

What are the critical elements that must be redundant to compensate for a possible failure on a multirotor?

Very logically this concerns the following devices:
  • motor propulsion units: speed controller + motor + propeller
  • battery
  • the central unit in charge of the flight management and stabilization: the Flight-Ctrl

The motor propulsion units: To ensure redundancy in propulsion, it is essential to have at least one multirotor with eight engines / propellers (as configurations with 6 or 4 engines are not able to sustain in the air if one engine came to fail).

The battery: Two batteries are required and must be connected in parallel. In this way, if one of them had to give up, the second could continue to provide enough current to allow an emergency landing

The central unit, in charge of the flight management and stabilization: A second Flight-Ctrl is installed as backup and will automatically take over, if the main Flight-Ctrl could fail.


As usually, the German manufacturer is the first on the market to implement this redundancy in is flight-control system for UAV's

This setup is based on an Okto powerboard (foreseen for eight engines), that has a duplicated data bus between the speed controllers and the 2 redundant Flight-Ctrl's and two battery connections so it can be powered by two LiPo's in parallel (see diagram below).

The powerboard is available in two versions: the Okto-XL for engines with up to 30A per motor consumption and Okto-Ultra version for larger configurations.
