This site (http://www.digitaltrends.com/cool-tech/swarm-of-little-flying-robots-is-amazing-terrifying-video/) has a short story and a 2 minute video of a mini-swarm of hand sized flying robots moving in unison, changing formation to move through openings, and running a figure 8 pattern.

Obligatory Skynet reference here.

Pretty cool actually, and I can see a lot of uses for them. Not all good.

One good thing is their bloopers video...these things aren't perfect. Yet.

Okay, I want that. Swarm of robots, ATTACK!

What I want to know is (and am too lazy to research), how long does the battery last on one of those things?

My crummy I"S"P (stated that way because I can't call what they're providing "service") seems to be actively blocking U-tube. I'll have to watch it when I get where the net works better. Looks very cool!

Depends of course on the battery, weight, and motor drain, but I've seen other small ones on the net that have run times of 15-20 mins.

That is so freaking cool. Me want!

I got the perfect music for them. (http://www.youtube.com/watch?v=Zd3bGpLpRZ0)

I was going to say that it better be that song, and it was! Great minds think alike. And sometimes I just get lucky enough to think like a great mind. :-P

Either that or Flight of the Bumblebee.

I'm curious how they do the flock behavior. Do they just brute-force the programming into each robot, or are the robots smart enough to work out the details, and the programmers only have to tell them to stay z cm apart and as a group do this formation?

I've read studies on flocking behavior in animals and it is actually modeled fairly simply. Though the behavior of a flock of birds looks complex, it can be modeled with just a few parameters, such as stay x meters from nearest neighbor and y meters from next nearests, etc.

very cool robots and reassuringly clumsy video. Thanks for posting this.

It's already been shown in simulations that what looks like very intelligent flocking behavior can be the result of very simple local rules, and I had hoped to see indications of that in the video, but to me it looked like plain stupid distance based individual predefined paths with no local intelligence apart from relative spacing in predefined formations.

Those things are dumber than a quite small pile of dirt and showed nothing to instill fear in me.

How about the James Bond theme? I just found this:

The quadrotors are playing musical instruments - sort of. They've rigged things up for them, but still, it's a bit ridiculous, amazing, and scary at the same time.

There are a number of videos on this YouTube channel:

Here they're building modular structures, though they use magnets to simplify things quite a bit:

Which included a music video, starring the robots. :eek:
