- Building a rope bridge with flying machines in the ETH Zurich Flying Machine Arena.
The video shows quadrocopters autonomously assembling a rope bridge. This is part of a body of research in aerial construction, a field that addresses the construction of structures with the aid of flying machines.
In this work, a rope bridge that can support the crossing of a person is built by quadrocopters, showing for the first time that small flying machines are capable of autonomously realizing load-bearing structures at full-scale and proceeding a step further towards real-world scenarios. Except for the required anchor points at both ends of the structure, the bridge consists exclusively of tensile elements and its connections and links are entirely realized by flying machines. Spanning 7.4 m between two scaffolding structures, the bridge consists of nine rope segments for a total rope length of about 120 m and is composed of different elements, such as knots, links, and braids. The rope used for these experiments is made out of Dyneema, a material with a low weight-to-strength ratio and thus suitable for aerial construction. Of little weight (7 g per meter), a 4 mm diameter rope can sustain 1300 kg.
The vehicles are equipped with a motorized spool that allows them to control the tension acting on the rope during deployment. A plastic tube guides the rope to the release point located between two propellers. The external forces and torques exerted on the quadrocopter by the rope during deployment are estimated and taken into account to achieve compliant flight behavior. The assembly of the bridge is performed by small custom quadrocopters and builds upon the Flying Machine Arena, a research and demonstration platform for aerial robotics. The arena is equipped with a motion capture system that provides vehicle position and attitude measurements. Algorithms are run on a computer and commands are then sent to the flying machines via a customized wireless infrastructure.
In order to be able to design tensile structures that are buildable with flying robots, a series of computational tools have been developed, specifically addressing the characteristics of the building method. The design tools allow to simulate, sequence, and evaluate the structure before building.
The location of the scaffolding structure is manually measured before starting the construction. The primary and bracing structure can then be realized without human intervention. Before realizing the stabilizers, the locations of the narrow openings of the bridge are measured and input to the system, which adapts the trajectories accordingly.

The apparent simplicity and ease with which these drones do the work hides hours of dedication and a lot of coffee cups .
Nice job!
You are the unsung heroes of the world. We need great minds like yours to move the world forward. Your work is very important to the progression of humanity. Keep pushing.
I, for One, Welcome Our New Drone Overlords
+Gary Rudd
I wonder who would be "the first", willing to cross a deep crevasse (canyon) on a bridge built by a drone. (no safety back-up either).
+job guy BigDog from Boston Dynamics :)
Or just use a backup.
+job guy Its not so much who built it, but does it look safe?
this would have benefited from the 'Flight of the Bumble Bee' playing in the background.
Congratulations! Keep your research. The world needs brains like yours.
i'm amazed
This is really cool, I could see this being used in rescue mission and such.
+Bill28120 there are many videos showing how they can be used beneficially without stupid stunts like so many idiots accomplish near airports and crowds. Commercial use will be tightly regulated to protect the public and assure reasonable advances. Look up "UAV uses" on RUclips.
absolutely. I am investigating the trust into rescue robots and this example would be a great test to see whether rescue personnel would trust the robots construction and walk over the bridge! great work guys!!!!
+Bill28120 Good luck with that. Any damage to one propeller, or loss of one is instant death to the quadcopter. These things don't glide in that scenario, they drop like stones.
+John Smith They did a lot of bumping above just fine.
Bill28120 Well, when I race quadcopters and nick trees and stuff, at least half the propeller gone causes failure.
This is sick! Keep up the work...
+Sachin Ganpat haha,wanted to post the same comment.Totally sick
+Sachin Ganpat +stelios85 Robots don't get sick you clowns lol.
+Sachin Ganpat Came here to say Sick...Not "Totally SIck" which in hindsight is way better.
skynet
I see what you did there.
+Alexey Filippenko Hi.
+SkyneT, you finally arrived.
Cool considering that all they need to do is transport one side of a premade bridge to the other side and secure it. One human could cross and secure it even better if necessary. With special securing connections it could be even faster. Two of these bridges could fit in a relatively small pack.
I'd get them to make me a nice jumper.
Очень хорошие пилоты !
I saw the term 'autonomous' in the description above and I also had a look at some of the links. Can I assume the drones were pre-programmed rather than manually controlled. It seems a significant point to clarify.
+Geoff Wales Partially. They need a sensor net to work in.
+ApexMike It shows how useful drones will be, especially giving them more AI to navigate and complete set tasks. Sadly, the military will always be at the 'cutting edge', so to speak.
rehanging wires after a storm amazing
This is amazing, and what scares people is that drones will take photos in their windows. Get a brejk, this is real value ...
Nice project! :D
Очень здорово. Молодцы!
So much for the moat around my castle!😮😎
once they learn how to tie proper knote we are doomed. ;D
very impressive. would be interresting to see a little "how did we do it", showing some of the effort that went into it.
WELL DONE !
Excellent!
Now what would be amazing is if you guys get Boston Dynamics' Petman or Atlas to cross that bridge!
awesome accomplishment!
THEY TOOK ER JERBZZZZZZZZZZZZZZ
derk a durrrr!
tuk e durrrrrbs!
+Henry Hazlitt broken jaw!
Cocka doodle do!!!
+Henry Hazlitt lmao! I just watched that episode last night. So good.
Astonishing! Great job
Fantástico!! parabéns os envolvidos

Imagine one of the blades of the drones hitting against the beams and landing on the onlooking crowd in a real scenario xD
You just became my favorite person on youtube lol.
I want to make one suggestion; next time use little micro octocopters made to resemble spiders.
AWESOME!
Excellent.
inspiring bit of experimentation and research, great job and thanks for posting!
Impressive!
Absolutely amazing! The sky is no longer the limit... Keep up the good work!
Interesting videoclip !
awesome ..n it is just glimpse of future robot's.
awesome work man...
Those propellers need some protection, otherwise wind could make the quads swing from side to side and get caught on the ropes.
Amazing.
This is awesome.
Fantastic! Cool engineering and programming!
It`s wonderful!!!!
Wow. Just wow.
Now we need a BostonDynamics robot to cross the bridge, and the rescue the very attractive calculator on the other side.
😁😃🤙
Incredible
Amazing work!
Flying, mechanical spiders, wow.

All they have to do is get tangled once during the construction, then you would likely have to start whichever step it happened, over. I'm curious how long a span they could realistically construct across.
The larger the span, the larger the payload, the larger the drone.
The larger the drone, the less intricate maneuverability.
+job guy Why would they get tangled if they are programmed to follow a certain path? :)
+isl8
If you watch the video, they come "too" close. Also, that spool ends up leaving an awkward slack. Lastly, you would have to have a near WIND-LESS environment.
OK, this is pretty cool!
impressive. any outtakes?
Ну может быть когда нибудь такие роботы нам и помогут )
Impressive.
Here comes SkyNet!
amazing to see the great work
Reminding me of of auto repair drones in Starcraft.
Nice trick, but can you do the same outdoors without the VICON cameras?
this is just awesome
Genious!
Just Beautiful!
woWWW! amazing!!! :)
I really like that you used the term 'flying machine' rather then 'drone' :P
I usually say "RC" just to mess with people. :D
Wow so much epic, I would love to do things like this for a career,.
COOL!!!!!😁
this is awesome!!!
finally seeing the potentials of drones
keep up the drone work lol
So how do the drones localize so quickly and accurately? I see external cameras, but there must be more than that. Can you please shed some lights? Thanks!
If the fly machines can still do it without need of the white covered fabric, this can go for production
This is fantastic!
AWESOME! But can they make tea?
this is amazing
super awesome
Woah! Well done!
Brilliant. Keep it up!
Fantástico
The way of the future.....The way of the future......The way of the future......The way....
Awesome~!!
amazing!
Very cool - nice work!
amazing!!!
Pretty cool. I realize this is beside the point, but those scaffolds do not look very secure...dudes are lucky their body weight did not cause a scaffold to tumble.
what kind of drones capable to build the bridge for transport like cars or tanks?
pretty awsome :)
Who would say that Drones are just "for fun"? ;-)
impresionante
If they can build a rope bridge like that, I bet they could even build a sky net of some description
This is amazing :D I wonder if they ever crash into the ropes :P
+adribier nope, they use sensors to detect them
Works for me
this is so amazing!
That is so fucking cool.
awesome
Lets first send an army of quadcopters to Mars and build some colonies before we send humans!
Anyone else notice that it sounds like they're making happy guinea pig/rat noises whenever the camera is close enough to record the engine noises?
Awesome! Hopefully feminists won't be bugging these men doing their job!
in extreme condition, we send drone to do things.
but can these drone fly without problem and swinging around doing this under Strong wind day?
Very good research, but in real life we can't use it. How to build bridge 50m long or 100m? How to connect steel cable?
+Mihail Vovk not now....but soon....SOOOOON MUHAHAHAHAH
+Mihail Vovk For improvised bridges before a real bridge is built this is great. I think there are some heavy duty drones out there who are able to transport long cables and do that trick. It's not made for forever but as a short period, small bridge this is awesome
+Mihail Vovk they will use helicopters and spend few days doing it.. :D ....... this idea with drones is nice but only for small distances, (and for those distances it would be faster to just cut down a tree :D :D
+Katojana Aleksielsis
Would you be the first to walk across it?
job guy Me personally not. But there are brave people out there who do. See the rock climbers who free climb mountains to put in hooks for the people coming after them. But without any protection for themselves.
good
Basic income is coming by bridge ,as well.
Any more work in this area?
This is cool and all but it wont be a very good bridge since the drones arent cabable of making a taut bridge. This will only be a bridge good for a few uses before its completely useless.
That's where humans come in. We're still good for some things... ...for now.
+spoofer20 I think the purpose was clearly not to build a permanent bridge, nor does this prove that machines or drones aren't capable of such a thing. It demonstrates tiny flying things pretty quickly weaving a bridge strong enough to hold people, imagine the applications they were going for. Emergencies/rescue, travel/recreation, construction/maintenance, military, etc.
@@imagoatbah better than having a Slaughter Bot after you. 😊
Did you use custom code or something open source?
Bien , très bien, je pense que ça peux aider pour le futur dans des situation d'urgences, inondation, éboulements, bref pour les secours d'urgence, il faut soutenir ce genre d'initiative plutôt que de payer des sommes folles des footeux ou des pseudo -star bref !
come si separano tra loro e con gli altri oggetti?
perfect video for utilizing youtube's 2.0 speed
