Does someone saw the Zero Gemini Redundant Autopilot?

[Reginak]

What do you guys this kind of redundancy? How it works?

This is the sort of thing that needs to become common if we are to ensure that the industry operates as safely as possible. As for this particular system, no ideas yet and I don't fancy beta testing for them at this stage!

Looks like an interesting step forward but dual systems are not really quite it. A true triplex system with two out of three voting is the ultimate way to do it. I'm sure it will come.

Hi Reginak,
I have received my Gemini Controller and Z2000 gimbal a few days ago.
Have gone through the manuals.
will start the set up once the zero uav Octa reaches me in a few days time
But about ur question on Gemini redundancy...
its quite simple,
it has two GPS/Compass, two IMU, its two identical units which house the IMU internally, and the marking on it is Gemini S.. S for SLAVE, and Gemini M, M for MASTER.
the system auto detects the IMU functioning, GPS functioning, and Compass functioning.
if any one becomes faulty, the system will automatically change over to the other channel and use GPS/Compass and IMU information to fly the multicopter safely.
Many crashed have taken place by just GPS unit getting interference et etc, so the GPS and IMU are critical for good functioning,
and that is what Zero Uav has done smartly. It has taken care of the Inputs.
However, the redundancy is not for the outputs. Meaning, the ESC still will operate from the Gemini M, Master.
Regards
Ramesh Tahlan

MK is pushing their new "redundant" system too - but, like ZAxis says, it ain't the real thing without three systems and a voting scheme. Micropilot does it - http://www.micropilot.com/products-mp21283x.htm - but only for heli and fixed wing.

I think they have uses 3 ch redundancy only for helix and planes, cause there is only one motor to control. With Multicopter specially OCTAs, with 8 motors must surely be a much of a herculean task. But the way things r going, i guess someone will come out with redundancy even at output level of controller. What with cost of machines with high payloads being huge, and add to it the cost of payload itself, specially the 4K resolution cameras. I think in the Multicopter arena Zero UAV has at least got the redundancy at the input level, which is really great for a start. And i am sure zero uav must already be working on redundancy at the output level... or at least let us hope so.
But would like to see how the 8 ESCs for an octa will be made redundant... specially for 3 channels... cause that would mean having 3 ESCs for each motor... that makes it 24 ESCs for an OCTA..... really wonder.....cause esc failure have known to take place... i have had three esc failure up to now on diff occasions, and have now changed over to another brand, and at three times the cost.
