When will you people learn that this sort of silly stunt embarrasses and angers the Quadrotors? They are biding their time people. Biding their time.

These quadrotors are showboating.

Every time I see the quadrotors doing something incredible, and I worry for the survival of our species, I watch this video and then I feel better.

Yeah, but those are all errors made by the humans controlling those robots...

Sometimes, it's hard for me to see all these cool things people are doing with quad rotors, considering that I used to be one of those guys (one of many papers on our lab via random google search), but I transferred to a different position two years ago to be closer to my/my wife's families. That job was probably the coolest job I've ever had, and things like this make me miss it. And make me GRAR just a little that all those videos we got through the public release process years ago still haven't been put onto Youtube, and thus, academia gets all the glory.

What makes these quadrotors work so well? Is it mainly due to the stable flight platform from the four rotors, plus very accurate dead reckoning with accelerometers?

Evidently not. Those are bloopers for the "Aggressive Maneuvers for Autonomous Quadrotor Flight" video in the "previously" link.

smackfu, motion capture cameras. Like the kind they used to make Gollum or Beowulf, but fed into the flight control loop in real time as opposed to post processed for cool CGI.

They ought to make a band out of this, kind of like the Flying Lizards.

I was the 13th Robot Quadrotor, but the band left me in an Applied Sciences lab in Hamburg the week before TED. Now I clean air ducts. It's a living.

Oh please oh please we need a Bond film where the enemy is nothing but a swarm of robot quadrotors that would be SO AWESOME especially if little evil faces were sketched up and glued to the front of them.

Having seen The Doberman Gang as a youngster, I now confidently predict a heist movie prominently a swarm of quadrotors.

prominently *featuring* rather.
posted by SPrintF at 7:14 PM on February 29, 2012


One very practical use I can see (beyond the obvious military and police abuses uses) would be equipping larger quadrotors with lightweight digital HD video cameras for the movie industry - locking onto, following and filming a moving vehicle or person from several simultaneous angles while automatically avoiding obstacles such as bridges and utility poles. Much safer, cheaper, faster and way, way more versatile than a helicopter shot.
posted by CynicalKnight at 8:30 PM on February 29, 2012


I don't know about automatic obstacle avoidance, but there are RC quadrotor camera platforms (for instance).

Not quadcopter but Malcolm (trailer) does feature radio controlled cars robbing a bank.

Interesting. So that really wouldn't work outside or in open environments.

Not without some modifications. You'll notice that many of these pre-programmed demos that different groups are doing are indoors for exactly that reason. Not to say these sort of things aren't useful - they allow you to focus on other problems, instead of spending a bunch of time on things like less accurate GPS solutions, windy days, reserving airspace, and general bad weather. Also, the position/attitude from the mocap may be augmented with accelerometers or an IMU, but make no mistake, the mocap is what makes this all possible. I don't know what the state of the art is right now, but a few years ago, real-time 100 Hz millimeter-accurate data on multiple bodies was possible using off-the-shelf mocap, and I don't know that you really need more than that.

The pilot episode of The River had a brief shot of a quadrotor being used by the group.
