I'd call it a Drown.
Pun intended?
Brilliant
I know it's a bit of a delayed laugh but..... Hahahahahahahahahah
So now we will see not only video's with hawks and eagles attacking drones, but also sharks and barracuda's :)
Amazing breakthrough. They need back propellers too. Have a switch that puts it is sub mode to activate the rear propellers. I noticed when it tried to move forward underwater it didn't do too well.
never work until they can figure out to send the signals wireless
+Mikey Rothwell Hi Mike, thanks for the comment. Unfortunately the comment didn't make it into this video but they will be using acoustic signals underwater to control it wirelessly. Evidently that technology already exists.
+Rutgers Today Acoustic signals travel at the speed of sound. While the speed of sound is very fast it is still nothing compared to the speed of light. Lag is a serious concern and will limit the distance the drone is operable from.
+Mikey Rothwell this could be fixed by a deployable/re-trackable antenna that floats on the surface , though that can cause problems with excess weight. the issue i am seeing is stability in water. i wonder if they have looked in to rotation method of the aft propellers or going with a 6 propeller design (4V, 2H) for more smooth horizontal traversing.

Perfect for underwater footage of swimming movement analysis! I love it!
Great ideas and efforts! Highly appreciated!
What is the tether specification, anybody can help?
I would like to do exactly the same drone but mainly for underwater usage? Thanks
Imagine fpv racing drones like this! Racing in air and underwater 😂😂😂 that would be crazy!!!
Great edit! Thanks for sharing!
@0:30 There is a very good reason for that. Specialized vehicles that can perform one task really well is better than something that can do several tasks moderately well. That is why the Military doesn't use single vehicles for a wide range of tasks very often, and why the Military seems to have many different vehicles and many variants of each, because they are all specialized for set tasks.
Can see lots of applications. Neat!
Is there a chance to intall bigger batteries? The teather makes it inpractical, and yeah, I know the teather it's for testing purposes.
Can u or anyone pls make a tutorial of making this drone?pls send me the link if there's any.
is there any update in these drone and can we get some material regarding this project
Is optic fibre guidance system utilized here?
I am asking this due to the fact that the majority of sl torpedoes are guided with optic fibre.
i don't want to belittle your innovation but the way video is edited gives an impression that you just waterproofed an already existing drone technology. It doesn't do justice to your hardwork; plus, disappoints d tech enthusiasts but still you rocked.
I'm not sure there is anything more to see in that school project. It's a waterproofed drone running a regular flight controller.
With a reversed set of props. gravity works too slowly underwater
@@iz723 it's about the friction, not gravity
That's awesome!!!
it's basicly a waterproof drone
Surprisingly practical. Nice!
Sure it starts off with bridge inspections.. Then someone comes along and attaches a handgun to it. Then it becomes an armed bridge inspector.
+cbmira01yt Or a Flame thrower - Then it becomes an armed flame throwing underwater bridge inspector LOL!" (Good point!)
+cbmira01yt 'Sergeant, the bridge inspector drone has become sentient and has gone postal!' 'BY GUM, I KNEW THIS WOULD HAPPEN'- ok time for me and my imagination to go to bed...
Hi I want what are the components required for this project
This seems totally military oriented
+leswoodies2 Exactly my point as well. "Underwater bridge inspections......" Naww, the concept is most likely sold to the military just like the Flame thrower was.
+leswoodies2 Yeah the navy wants to be able to deploy drones from there submarines, something like this would be able to deploy and be recaptured by the same sub without the sub having to surface, basically sub gets better SA and keeps it's stealth.
You do realize that a lot of military tech makes it into the consumer space right?
Scientist should think about how to make the world better instead of selling stuff to the military. Shame on them.
they do both in general , alot of military tech has become mainstream tech. Military computers for example were very important in helping the development of computers in general
The beginning of the end for Aircraft Carriers (once you realize what a MUCH bigger version of this would be able to do; and not just go underwater)?
Enjoyed this video, thumbs up. Cheers from Sint Maarten
Can it be bought ? BEcause I looked up in google and didn't find anything ...
I wonder how many amps those brush less motors are drawing due to the resistance of the water.
I wonder whether they change modes when in water otherwise I imagine the motors will burn out
Water cooled you know..
They of course dont go full throttle under water.
propeller which can be used in air and water...is it possible??
pretty damn sure i saw this in Red Alert 3 XD
Gotta love how they actually promote it's use in military equipment 0_o
can i have the journal/research paper on this? im trying to make a research into this as well and it's quite interesting to see! im a student from Indonesia Btw
very cool bro!! subbed
Wow so nice drone
which motor u have used in this drone???????????????????
The ideas nice, even i was thinking same of a similar kind, but I don't think a rotor mechanism would be efficient for such an amphibious craft.
what SERVO motor did you used?
What pressure can it stand
How to fabricate this robot and what are components should be required
what is the cost of the product where can you order
I wonder how much weight it could carry, as well as the rate at which cost increases or increases as you scale up it's size. Could this possibly be an effective way of collecting water samples to monitor coastal biogeochemistry, (as opposed to having a stationary sampling device, or field crew)?
Nordstream1/2?
Cool!
i wonder how it can handle all the thrash, fishnets and ropes in the ocean. props no good there ^^
How do flying drones handle hitting a tree?
They fall to the ground. Good luck diving to get your sinking drone
kodguerrero Just pull the wire.
@youtubeShadowBan A submarine can't fly up under the bridge. Even if your tried swinging the sub by the wire like an idiot, it still won't reach most of the underside.
Build multiple saws within it and allow it to go clockwise and counterclockwise to cut through multiple things that stops its movement.
holaaa lindo video me gustaria que permanezcan haciendo contenido de la misma calidad!!! Voy a seguir mirando sus creaciones. Les envio un abrazo nos vemos luego ❤️👍🏽
КРУТО ! скоро у всех такие будут :)
Wouldn’t EDFs be more efficient for underwater maneuverability?
Where can you buy it?
Perso, Je pense que le system à double hélices à rotation inverse est trés bien pour l'air. Autant la forme des hélices n'est pas adaptée pour l'eau (trop de déperdition de puissance). Il faudrait, peut être, mieux profilée pour l'eau les hélices inférieures. Celles ci ne fonctionnant que sous l'eau. Pour les hélices supérieures, leurs permettre de se replier sous l'eau, ou avoir un pas adaptable plus approprié au milieu aquatique. Peut-être un mixe des 2 solutions.
when will it be released
It looks like there are some structural issues. Also not able to move effectively in the water. Looks like a mild current would defeat it under water.
when it will be released ?
Very interesting boys !!! Just remember , when they were riding horses they said automobiles ?? Naw that will never catch on ... so keep up the good work ... will you send me one when you put it on the market?
Put cones around the props so it can maneuver better underwater and should be able to fly to .
Not yet but I'm going back in time for work
ohhhh so it's just the more advanced version of this thing that people think are aliens
Are you using your brain?
@@Buttcakes15 I feel that I am. I'm always skeptical and prefer to rule out all rational explanations before deciding to believe the more unlikely one. I do believe there are other planets in this universe that have life on them, but I highly doubt they've made it all the way here.
@@weeaboostarshine435 believe it or not, I’ve always been skeptical of ufo’s until about 2 years ago when the government released the 3 iconic videos and confirmed their legitimacy.
That was the turning point, and you pair that with the testimony from Commander David Fravor who actually chased and engaged with one of these things. That testimony was one of the videos released by the government.
So you have a very reliable source saying mind bending things, paired with the videos that show mind bending things that you can actually see with your own eyes.
As a former skeptic, it’s hard to refute.
hay thats pretty cool
Excuse me , can i have the full research ??
Why are the motors themselves rotating? What is the purpose of that and what type of motors are being used on this vehicle?
They are called outrunner brushless motors. The coils are stationary and the can which is lined with magnets rotates around the coils. These motors are very common in today's rc airplanes, helicopters and multirotors.
wow
That is not a robust underwater vehicle. You need to install an auxiliary propulsion system.
I just thought about what to look up today, and I chose "Underwater Drone"
Good thing
How fast can it go under water
props in the air and sort of jet in the water? :D
Great video! Keep up the good work and come join us and leave your link in our Forum!!
wow... cooling problem solved!... :D
Let's take one surfing!
+Ho Stevie! I think it's designed with better intentions in mind lol
TheMusketITuckedIt haha definitely
ติดใบพัดหางเรือเพิ่มเวลาลงน้ำ
Wow
Sweet cord coming from it..
Thanks. We like it too.
Now what we need is a diving helicopter!
I've seen waterproof quadcopters. This is great but they shouldnt say they're the first
+GoldenDive007 Then who was? This is the first time I ever saw a drone fully operational underwater and in the air.
Cool. Yeah salt water is very conductive so could be an issue. Given the motors are effectively shorting out under water this would cause rapid corrosion. Fitting ballast tanks and conventional prop like a submarine would be better than the rotors as these would flex under load. Interesting concept tho 8\10..
POV: you seal the electronics of a drone and put an antenna that sticks out the water.
its just a few line more of code and waterproofing the copter.....
+Calvin C One does not simply 'write more code', at least in my limited hobbyist experiences.
+Calvin C
have u seen the cable... that was necessary, as rc tend to not work under water.
fácil solución se ínsula el área de los motores no le entré agua caballeros
I have to ask why a cable is needed when 27mhz, 40mhz, 72mhz and 433mhz rc gear all work under water and are commercially available.
+Tom Hugill Freshwater yes, but not at all in seawater.
All drone work under water as long as you waterproof it
You'd have to find a way to shield those brushless motors from water if you want to take these into the ocean. Salt water rusts the bearings in brushless motors. Other than that, this type of craft may see real world use.
+flyingchimp99 environmentally sealed bearings.
sneescampers If salt gets into a motor the bearings are going to rust quickly. I had a customer who ended up submerging his phantom 3 in the ocean for 30 seconds, he took instantly grabbed a hose and poured fresh water all over it and inside it to flush out the salt water but it was too late.
A mere 30 seconds of exposure and within 2 days the motors wouldn't rotate.
Was over a 600 dollar repair.
Why is there a cable connected?
Andy Barus most submersible rovs have cables because radio signals travel poorly through water
WOW! This is to risky for my Mavic :)
DJI needs to do this :D
So......................................It's a waterproof drone then?
obviously
A fascinating problem the video doesn't really do justice to: Pitch and roll control with a quadcopter is pretty straightforward regardless of how fast the rotors are spinning, but quadcopters with fixed rotors (like this one) actually can't control their yaw aerodynamically! Instead, they can only yaw by shifting angular momentum between pairs of counter-rotating propellers (speed up the CCW propellers and slow down the CW propellers, the net lift will remain the same, but the vehicle will yaw CW). Which means that available yaw authority (unlike pitch and roll authority) disappears as the propellers slow down!
So given that the speed of the propellers goes down ~1000 times when the vehicle is submerged, it means this vehicle probably has ~zero ability to control its yaw while underwater. Notice how in the video we never really see it yaw while underwater? Just pitch and roll? That's probably because it can't yaw underwater! It needs an entirely different set of control laws underwater that rely only on pitch and roll! It would be a fascinating controls problem to figure out.
it has a cable because the signal can penetrate water very far
Can u explain how it works under water with signsl transmitters
it can't yet ( the signals go through wire)
it's easy, you only change the frequency to one compatible with water instead of the one used in air. That's how simple it is.
like which frequency? If you use VLF you'll get up to 20 meters below the surface, but your antenna will be of the order of 2.5km long
jessbrown99991 I dont know the exact frequency, but studying Fisics I saw how it depends on the frequency in each material (it's density is proportional to the frequency you need). And the air is the less productive material because it is gas and waves travel better in solid materials or in liquid, in this case. So when density is bigger, it's better to transmit information.
Maybe it would be similar to RADARs.
PS: Srry for my english, it's too early in my country rk.
Black magic
Not sure what makes this amphibious vehicle any different than a standard multirotor beyond water proofing. I would imagine that all one would have to do is water-proof an over-the-counter multirotor, then, once it is immersed, immediately lower the throttle settings so that the prop RPMs would not be too high within the new fluid medium (they'd also just need to pick a decent motor kv that would allow for reasonable operation at both RPM ranges). You might also need to simply assign a switch on the transmitter to change the PID settings of the flight controller, once it's immersed, in order to change the reactivity of pitch, roll, and yaw.
+AEMontoya
And put on wire control to have signal underwater
i think the best for it has a propeler for water
What an excellent tea bag.
why not add a sideways propeller, for only underwater propulsion? :/
What's the battery life like on that thing?
there is no battery do you see the wire that supplies the power
The wire will be for communication not power. Radio, specifically microwaves, do not penetrate through water so control must be done via a wire or through autonomous software.
Can you repair pipelines? Or only destroy ;)
Nice invention!!
Time will tell how long that drone can fly without the sealed motors overheating, overmore what type of remote control are they goung to use that penetrates more than a few ft of water!!
I guess those kind of drones are/will be autonomous :) ... So no direct RC
Sonar controlled? :)
out runner motors don't use brushes so actually they don't need to be sealed from water, just the motor control circuits
GIVE ME PLZ THAT THING!!
It isnt wireless because it is not supposed to be controlled.
Many drones are capable to fly on their own.
The game has changed.
amen\
i have new idea about these, i'm already done it.
That is not a first. The same thing that makes any drone fly will make it maneuver in water. Like everyone states it will have to be wired..
Parth soni an Indian . Jai Hind 🙏
what happend to youtube tonight? it doesnt work!
Good effort by the design is inefficient and dont think it's gonna work at all while navigating through strong currents like in a river
So a waterproof drone...
