sorry for the late info... happened allready in september 2012...

but better now then never :-)


Hi all,

there is more back groundinfo (thanks Joshua!)

quick answer to some questions right away:

1) it's hummingbirds (Asctech

2) pure GPS and a very stable Autopilot (standard-Hummingbird with some minor tweaks)

3) communication: liard-modules 2,4GHz (telemetry and light)

communication protocols will change in the future, since the bandwidth at the time of the recording is fully used by this "alpha protocol" we've used there...

4) collision detection has been done on ground control (laptop) - no extra sensors/intelligence on board

5) we had to add some functionality to the hummingbirds - but auto-pilot and stability is "of the shelf" from Ascending (who's support was invaluable... big HUG to Daniel and his team @ Ascending!!)

I'll give a more detailed talk next week in Oslo (at the OLSO LUX-Festival)...

and we're (hopefully) flying a "version2" show in Australia this Summer - I'll keep you informed!

best regards!

What a GREAT UFO triskter gadget !

How the heck did you coordinate them? i.e. collision avoidance. gps doesn't seem accurate enough for this.

Matt, I think they used mavlink to communicate with each other and maintain separation. There was a thread about this when it came out, let me look around for a second and try to find some links.

It's mesmerizing artwork, indeed!

There would be a ground command station (flight control) that communicated with each individual drone. They would all be constantly sending data about their current position, and flight control would react in real time to deviations from the ideal course. Each movement is thus specified by this server and all sequences of movements continuously checked to prevent collisions. If need be, the server could intervene to correct a flight path, recalculate all position data, send this revised data to all individual drones, etc.
