After seeing these mind-blowing quadracopter videos from UPenn popping up online all over the place for the past couple years, its great to finally see a culminating talk about the work being done there. Congrats guys!

Can they deliver me a burrito?

miahi• 14 years ago

You have to sudo for that.

hugs• 14 years ago

Would make an excellent start-up idea. :-) Please do it, someone. I don't have the time, but need a burrito. For pure zeitgeist win, add grilled cheese to the menu, too.

tambourine_man• 14 years ago

A bit scary but very cool.

dLuna• 14 years ago

Am I the only one who wants to mount a nerf gun on a squad of these and then play war in the back yard?

sologoub• 14 years ago

I'm sure pentagon types are thinking just that... minus the nerf part. :)

The first thing I thought of how many lives could be saved with scouting buildings.

nwatson• 14 years ago

The second thing I thought of was how cross-border and urban illegal drug distribution is gonna be made much easier with this. I won't be part of it, but, just sayin'.

javert• 14 years ago

Maybe I missed it, but contra the title, I did not see any robots flying in the TED venue. Since I've seen most of these other vids (but not that), that's what I was looking for :(

falcolas2• 14 years ago

The quadroter in the gentleman's hand landed there at the start of the talk, but otherwise it was all in the videos.

robotresearcher• 14 years ago

On of the students is carrying an RC remote when he comes on stage at the end.

It would be very hard to fly these little guys autonomously at TED, since they use the off-board Vicon multi-camera IR motion-tracking system in their control loop. That's a big, expensive installation in the lab.

Kumar's group is very well respected in the field. They've had several years of strong innovation. Vijay is really good at what he does, and a nice guy.

jjwiseman2• 14 years ago

It might have been too much effort to set up the multi-camera Vicon motion capture system at TED, calibrate it, etc.

And unless they put them inside an aviary, which would also obscure the drones, I'd be a little worried about losing control of a machine with several exposed spinning blades in an auditorium full of people.

cdibona• 14 years ago

They've set up exactly those before at Ted, but no, they didn't do so this year.

tommoor• 14 years ago

Yep, most misleading title ever.

TeMPOraL• 14 years ago

The other talk (not yet on-line) featured a remote-controlled hummingbird drone flying around the TED stage.

modeless3• 14 years ago

The Kinect-mapping quadrotor was the most interesting demo; that could be useful today. Imagine letting loose a swarm of quadrotors in a large building and having a complete map and textured 3D model of the interior and exterior within just a few hours.

tobias3• 14 years ago

The Kinect has a very limited range, is not accurate and works only in certain lightning condition. That's why they added a laser scanner. Those are over $1000. Then in order to build the map via SLAM in real time you need a really powerfull PC/Laptop. Even a netbook is not going to do it, at least for the SLAM in ROS(ros.org). Then it looks like they added a all angles are 90° assumtion, because normally the map does not look that nice because little errors accumulate. So it will take a while till we see something like that outside universities.

jjwiseman2• 14 years ago

Laser scanners have become a bit cheaper (and smaller) in the past few years (Thanks, DARPA Grand Challenge & Urban Challenge).

Neato Robotics has developed a planar scanner that costs $30 to build--It's on their robot vacuum. See "A low-cost laser distance sensor", http://ieeexplore.ieee.org/xpls/abs_all.jsp?arnumber=4543666...

wavephorm• 14 years ago

Hey quit being a letdown, this really amazing stuff. You should reword it more like:

"The video is showing amazing new thingamabobs that will get less expensive over the next few years, and pretty soon you will all be able to use robots like this in your everyday life".

modeless3• 14 years ago

Kinect-like sensors are going to improve very quickly (http://www.theverge.com/2012/2/29/2834088/samsung-camera-sen...), as are SLAM algorithms using Kinect-like data. High cost isn't necessarily a problem for this application, as one team of copters could map many facilities. Computing power can be mostly centralized at a base station that can be as beefy as you want. Certainly a commercial product is years rather than months away, but I think even this limited demo could already be useful for e.g. mapping the nuclear reactors at Fukushima.

ThaddeusQuay2• 14 years ago

"Imagine letting loose a swarm of quadrotors in a large building and having a complete map and textured 3D model of the interior and exterior within just a few hours."

This reminds me of: "I’ve long been interested in Navicubes, which is what I call a small and not-quite-here yet $5 box that always knows where it is, which direction it is facing, and which way is up. Besides vehicle nav, intelligent toys, and robotics, these would open up all sorts of neat tricks, such as a ball you could simply bounce off cave walls for mapping."

astrofinch• 14 years ago

It sounds cool, but this seems like a very expensive way to accomplish a fairly mundane and useless task...

The problem with trying to make money using robots is that we still have plenty of people on the planet looking for unskilled work. I don't think we will reach the economies of scale necessary to make robots practical unless that changes.

njharman• 14 years ago

Um, many industries, auto, electrons assembly have All ready been robotized. People are expensive, have short work cycles and break down often, and require much more maintenance and infrastructure. You have missed the revolution buy a hundred years

baddox• 14 years ago

For many (perhaps most) buildings, I imagine a simpler wheeled or tracked vehicle would be just as effective and surely cheaper, more reliable, and more robust.

tybris• 14 years ago

Why? These robots look pretty simple and have no problem going up stairs.

modeless3• 14 years ago

Navigation for land based robots is a much harder problem. I would expect quadrotors to be more reliable actually (only four moving parts! No ground contact!) with the ability to map areas inaccessible to wheeled robots, and much faster to boot.

aqme28• 14 years ago

I can't help but think that that swarm-building-a-cube algorithm could be vastly improved. Those robots are doing a lot of waiting around.

wittgenstein• 14 years ago

Amazing work from the Penn GRASP lab! This is ground breaking!

notatalker• 14 years ago

That was weird. I read, "Aerial robots swarm the stage at TED". I thought how rad of a demo that would be. Then I saw "[video]". And got excited to see video of a TED talk with robots swarming the stage.

The canned video they had was riggin' rad, but I was disappointed. Damn you, Ken Fisher!

fmstephe• 14 years ago

This is just the thing I love to see on Hacker News. Every time you see this I remember why I spend all those hours hacking and learning. Really lights a fire under your ass.

learc833• 14 years ago

One of the things I think of when I see autonomous quadrotors is a localized missile defense shield.

A swarm of disposable quadrotors surrounding a ship, set on a rotating recharge schedule, that intercept missiles and detonate a small explosive payload.

3lit3H4ck3r2• 14 years ago

Unfortunately, I agree. From the first time I saw this technology the top application that jumped off the page to me was of a military nature. Perhaps a day will come when this may not be so. Until that day comes, tech like this, I believe, will save lives; on and off the battlefield.

gnosis• 14 years ago

Save lives, or cost lives (or both), depending on who's in charge and what their aims are.

bhickey• 14 years ago

How would this have any advantage over a defensive system like Phalanx?

learc833• 14 years ago

It would be much harder to overwhelm with multiple missiles.

You have to place Phalanx systems all around the ship in order to provide 360 degree protection. However, an enemy could concentrate multiple missiles on a space covered by only 1 Phalanx.

If radar detects multiple missiles inbound, more drones could be easily be routed to the appropriate area to intercept. To overwhelm the defense you'd have to fire more missiles than the ship has drones (and since drones could be made much more cheaply than supersonic missiles, that would be fairly hard to do).

ww520• 14 years ago

These things might be too slow to intercept an incoming missile, especially the super sonic ones. The quadrotor doesn't look like very energy efficient. There are 4 rotors to draw energy. They must need to recharge pretty quick. With a large number of them, the energy draw from the ship is pretty demanding.

learc833• 14 years ago

>With a large number of them, the energy draw from the ship is pretty demanding.

There are destroyers on the drawing board with enough excess capacity to power rail guns, and the latest aircraft carriers have upgraded reactor units to power the electromagnetic launch systems they use instead of steam catapults.

The reactors that supply these large ships should have plenty of excess power for a few hundred drones.

>These things might be too slow to intercept an incoming missile, especially the super sonic ones.

They don't have to match speed, they just need to place themselves in the path of the missile; they are incredibly agile and shouldn't have trouble doing so.

joshu• 14 years ago

Blah, I was at TED and missed this. Dangit.

iwwr• 14 years ago

Can we get the designs of these robots somewhere?
