Autonomous Overhead Powerline Recharging for Uninterrupted Drone Operations - ICRA 2024
Вставка
- Опубліковано 31 січ 2024
- We present a fully autonomous self-recharging drone system capable of long-duration sustained operations near powerlines. The drone is equipped with a robust onboard perception and navigation system that enables it to locate powerlines and approach them for landing. A passively actuated gripping mechanism grasps the powerline cable during landing after which a control circuit regulates the magnetic field inside a split-core current transformer to provide sufficient holding force as well as battery recharging.
The system is evaluated in an active outdoor three-phase powerline environment. We demonstrate multiple contiguous hours of fully autonomous uninterrupted drone operations composed of several cycles of flying, landing, recharging, and takeoff, validating the capability of extended, essentially unlimited, operational endurance.

That's how birds recharge actually.
I think you mean "birds" because everyone knows birds aren't real.
You really believe that?!? Wow birds arent even real smh
i love youtube comments! really, it's the best parte of the video
Yes birds are comunist putin spies ...
I was looking for a comment to make, in vain, but you found it 😂
this is wild! Thanks for posting!
A fleet of these to steal electricity from power lines and charge my home battery.
I need this on my Nazgul 5
You've done it. You've given them a way to feed. Now they will multiply, unhindered. You've brought the apocalypse upon us.
this is such a cool idea! i wonder what power companies would think of this though
It is meant for power companies who use drones to inspect power lines.
Certainly better than Helicopter inspection teams! 😬
#TheyStoleYourJob 😅
Pretty cool stuff
Reminds me of that one UAP / ufo thing from the 1990's 2000s early
What if you flew the quad up there had it sit like its charging but sends down power via an extension cord, could you power other things?
Drone parking, storage, and charging. Sounds like a million dollar idea. 💙 T.E.N.
A million? What is this, 1995? A million will buy you half a house anywhere worth living, or maybe a few engineers’ payroll for a year. If this is a million dollar idea in 2024, then this tech will never see the light of day-at least in any non-academic (commercial) capacity anyway!
Badass. Don't let your electric company see this lol
WOWSERS!
Fancy seeing you here Ken!
I need this for my DeWalt batteries.
How does this charging circuit work with just 1 conductor?!
The energy harvesting does not rely directly on the current but instead on the magnetic field around the wire (which is of course induced by the alternating current in the wire). In fact, there is no conductive connection between the drone and the power line at all (e.g. metal to metal) since the harvesting principle is more like the wireless charging for your phone.
Induction
There is an opening current transformer. Current measuring tongs work according to this principle.
it's just physics
@@nicolajmalle9715is that why it's only charging at 50W on a 155 watt hour battery? 0.3C rate. Or maybe that's on purpose to increase lifespan of battery?
Single line. Low res?
i like it
Will using the magnetic field of wire to charge making the resistance or loading to the wire increasing, so eventually the cost of charging still be there?
It's not free if that's what you're asking. It uses power just like your house does. If you used one of these drones, it would be theft.
This is a really great idea, but arent there like, legal implications to actually doing this without permission?
DOD here. Does it work with the parkistani powergrid?
Inductive charging will function with any power line that carries an alternating current
Don't tell the terrorist!
By doing this, it increases the resistance of the power transmission system. If the number of drones increases, it will significantly affect the power transmission efficiency, which will likely be a cost to the electricity consumers..
50 watts is nothing and these are going to be very expensive
Excellent idea. They fan even be used as security patrol drones for farmers fields.
Dobrý den, v laně je kladný pol, kde vezmete záporný? a jak a kdo zjistí kolik zaplatit za energii?
Dobrý den, tento princip nevyužívá uzaveřený okrih. Je zde využíváno magnetické pole generované vodičem vysokého napětí. Jedná se o podobný princip jako u bezdrátové nabíječky na mobil. Dron je vybaven "příjmačem magnetického pole", který převede na el. energii a následně uloží do baterie
@@slovakto1 aha, tyo díky moc, parádní řešení
How do the powerlines affect gps? Is it still usable?
The main disturbance is to the drone's internal compass due to the magnetic field around the powerline. That's the reason for using two GNSS antennas (black device at either tip of the white wire guide) which allows the drone to extract its heading that way
@@nicolajmalle9715 Thanks!
Awesome! But also need to pay PGE for that haha
Hmm... Weren't some UFOs seen operating near/on power lines some years ago. It was as if they were recharging.
Utility company will be coming for your energy bill
We are actually developing this in close collaboration with grid companies who are interested in the technology.
You harvest the energy by magnetic coupling, don't you?
Seems to use a current transformer based on the fact that they state that the charging power scales proportionally to the current in the power line. So yes, I think you could say that it is inductively coupled.
Yes, it's inductive charging from the alternating current. If you are interested you can read more in this paper:

Man I had this idea back in 2015... next we'll see an automated search and rescue follower (for light and infrared) drone.
На выставке в России в 2013 был представлен БПЛА "квадрокоптер" (действующий экземпляр ) с тем же принципом подзарядки от ЛЭП, - европейцы сильно отстают.
В части воровства электричества русские впереди планеты всей.
@@USER-ruzer2000 каждый видит что-то близкое своё, да 😉
При этом российские компании энергетики, одни из самых крупных и прибыльных в мире, а судьба того интересного БПЛА неизвестна.
Да, мы все знаем, что Россия изобрела технологию дронов в 1857 году. И все остальное тоже было первым в России. Лол, идиоты.
this little hack is what power companies don't want you to know
Power companies will need to strengthen their lines to carry the weight of all the drones getting a free charge 😂😂😂
Skynet is coming...
so you have L but what about N i mean how is the electrical circut closed?
Oh I need to get one of these just carry a cord up tp a power line and I'm charging my eclectic car any where that has open lines.
How effing low are these lines??? From the angles in the video, the lowest phase looks like it dips below the level of the fence beside it! If these are carrying anything above about 50V, that seems like the mother of all safety hazards!
This is a customized power line environment with each of the four cables hanging roughly 2, 4, 6, and 8 meters off the ground respectively. For these initial results the power source is 5V 50Hz maxing out at around 300A.
its amazing that people don't understand that things exist outside of their true working use. Like yes these are obviously custom PRIVATE lines for testing just this. People are mind-numbingly stupid these days and cant do even a little of their own critical thinking.
So it can scale up to thousands of volts, I guess will have applications in Ukraine knowing those Americans
Because Terminator wasn't real but now you are trying to make it real. Didn't you watch the movie.
Ain't that stealing ?
So people are going to start stealing electricity all the time now? How will they charge people for this use?
I do not see this being a big issue for awhile. Most urban lines are buried anyway. By the time this becomes commercially available and affordable, how many drone enthusiasts are going to rush out and abuse this? And why?
congrats! you've added so much extra weight with the recharging mechanism that you now NEED to recharge far more often. This system has practically exceeded the point of diminishing returns. Go improve it and come back when you've actually got something useful.
Lmao, dude it has infinite power any where there's power lines. Even with half as much battery life, it's worth it for long distance unattended drone work
It definitely has a niche
Bro it's a proof of concept and the guy is putting this info out so others can use it. Don't be a jerk.
The heat from that power would fry the electronics, lol
What are you talking about, its 50 watts. A drone of that size normally charges at 200-400 watts.
This thing has barely and heat to deal with because the charging is so slow.
Why comment on something like this if you don't have an understanding of what is happening?
@@nocare Please educate me, not so technical. But in real use case the power is not 50W. EMI and arcing are other issues. Would power companies ever allow these drones? IDK
@@mahindersingh-wb3ik The power flowing thru the power line is going to be hundreds to thousands of kilowatts probably.
Say sits a typical 7.2kv power line. At 300 amps that 2.1 megawatts of power running thru the line.
But none of that is going thru the drone or any component of the drone.
The drone is electrically isolated completely from the line, its just a plastic gripper to hold it in the correct sport.
The drone itself is only getting 50 watts of power. It is stealing this from the alternating magnetic field the AC running thru the wire creates in the air around it.
Similar to how wireless charging a phone works but way less efficient because it's not designed for this.
As such the amount of power running thru the line effects the charge speed. The power line had 300 amps running thru it at the time of 50 watt charging. If it was late at night and say only 100 amps was running thru the line it would charge roughly 3 times slower.
EMI is a problem but only for the guidance system there is no chance of damage from it. Obviously all guidance issues have been solved enough for this demo.
Arcing is also not really a problem any more than it is for a bird.
If a bird would be fried in a particular scenario then so would a drone but birds are fine most the time thus drones will be too.
The power company certainly would like to have this capability along with AI to inspect power lines for faults, trees growing too close ect.
However for uses beyond the power companies interest that is a more complex question and would best be answered by each particular power company and the local government regulations proposed.
EDIT: Of valuable notice, this video is on a closed test area built for this purpose. As such the actual power thru the line was very low about 1500 watts or 1.5 kw.
A residential line is much closer to the example I gave as an average american house can easily pull 5-10kw of power by itself with no electric car during peak hours, and the hanging power lines you usually see are for thousands of homes and businesses.
The biggest question for this example that I would have, can the guidance system get it close enough to high voltage main lines for the computer vision to take over, or does the EMI prevent accurate navigation into visual range with the current research design.
Obviously more cameras in diffrent directions and for diffrent phases of flight could solve that if necessary.
Also of note I am a drone engineer in the USA. Thus my curiosity.
@@nocare A typical drone's navigation system relies on a compass to obtain the drone's heading. Due to the strong magnetic field near the power lines, the compass can not be relied on in this case. The drone in the video instead obtains a heading by using two differential GNSS antennas (black cylinders in either end of the white cable guide "horns"). The remaining system relies on a camera, radar, and IMU which are not affected in proximity to power lines.
A big challenge is EMI-proofing the whole system to handle high voltage. When we approach high-voltage (e.g. 400 kV) power lines, we see significant arcing and noise in the electrical systems which may fry sensitive components and cause instabilities or even crashes, like seen here ua-cam.com/video/4c5utNIk3Hw/v-deo.htmlsi=cBFxDpQUbnwFQJz_&t=41.
😂 will never going to production no one's going to have their power stolen 😂
This drone is literally designed for power companies to inspect their power lines...
