iam happy to see my finished cps5 drone as picture in your video.
Thanks again for the picture!
@@CPSdronewhy can’t you have one or two singular engines or motors and then open and close valves that exhaust at different angles?
@@dorjedriftwood2731 one issue is friction, adding long tubes for the exhaust with bends probably isn’t very efficient. Then there is another issue, the motors and propellers don’t just exhaust out the back, they also pull in the front, meaning when the motors are running you will always have a force coming from the intake. So fixed motors even with difference exhaust paths will always pull in the direction the motor is facing, regardless of where the exhaust comes out. This could be mostly eliminated by using two motors that intake in opposing directions but any difference in speed will still cause movement.
Edit: it also creates a control problem, you don’t want the motors to be spinning is you aren’t exhausting it somewhere which means you need to mix the controls a lot more and if you want multiple exhausts at the same time then balancing them could be difficult as more water will take the easier path. It is all possible but probably more hassle than it is worth. The motors are cheap and having multiple creates redundancy.
Can’t believe I had to wait till the end for a titan joke. Worth it.
@@CPSdronejust a thought, if you made a standard drone configuration yet made the submersible really heavy and prone to sinking very rapidly it would fly similar to a standard drone yet underwater
Ciekawie jest słuchać Polaków mówiących po angielsku, heh. Świetny projekt i trzymam za was kciuki.

I like what you all have done here. The ability to potentially build my own CPS 5 using your comprehensive guide is a really awesome idea. I took a peak at the website, and geez, it's done perfectly.
BIG NOICE, this will help everybody that wants to build an underwater drone and its an really good video. AWESOME!
AMAZING submarine and it is omnidirectional, great work keep it up
You might want to consider spot-welding the cells in the battery instead of soldering. It's a little risky to heat them!
That is true! I bought a "kWeld - complete kit" last year and was very pleased with it. But keep in mind you also need a power source or battery that can give enough amps. :)
Bardzo dobrze mówicie po na angielsku, świetnie nagrywacie te filmik i projekty macie niesamowite. Na pewno dużo czasu trzeba było na poświęcić. Ja bym to zobaczył na żywo też, i kiedyś zapiszę się na kursie :)
5:40 was such a great vibe. Come for the engineering, stay for the friendship :)
Nice! Put a bag of desiccant into the electronics module assembly (or fill it with nitrogen for high performance). Since you have two machined delrin endcaps with double o-ring seals you can probably use whole-copper wire or a custom circuitboard embedded in epoxy potting to make a good subsea penetrator, also face-seal o-rings combined with 2x piston seal o-rings help a lot. Also IMHO flat acrylic is better than a dome if you want to go deep.
Świetny materiał. Czekam na więcej.
Another super video! I am looking at new configurations for better vertical design to film up and down a line up to 150 mts so super excited to learn from this experiment.
Super impressive project and video! This channel is destined for 1 million subs in the near future!
well. thanks for creating this channel and wacthing every uploads just reminds me my study times. how impreasing this course even after 18 years my graduate.
Well yeah that thing will be slower simply from it not being tinkered with for drag at all.
That iteration of the drone is extremely successful for what you wanted it to do. Which was being omnidirectional in a compact design to prove it can be done.
Next step is refining it down shape wise so it can perform how you want it. Possibly make it so various panels cover the intakes for various rotors when not in use, and also positioning the rotors in spots that still allow for optimal use, but with the compromise of being more streamlined for movement as well.
Or better yet install heartier more powerful motors as well if it's truly just trying to get it to go fast with the current design.
Do not chalk it up to less then what it is which is an extremely awesome proof of concept for your hard work.
This is great!
You could have a spot welder with a cheap malectrics and an old car battery. Soldering directly to the cells can cause damage to the chemistry inside.
I know it's not as fast but i really like how well this ROV balanced itself out. It seems like if u could improve this one, it would be much better for navigation & exploration
Great work! Currently building something simmilar. You can make the dome yourself with an acrylic sheet. Clamp it in around the sides with a circular hole in the middle, slowly heat it in the oven and let it sag to the desired form. Alternatively you can use air suction on one side. It takes a few tries to get it right and even more to get it optically perfect. This is how we used to make the domes for our cameras in the past when there were no off the shelf housings. Good luck and happy diving!
Super robota chłopaki, tak trzymać
Super project! I love It!
Great work as always
thank you! and keep it up!
Super robota Oby Tak dalej :D
I've seen a few RUclipsrs stating that 3D printed components can leak even with 100% infill. I haven't tried it, but logically, the issue can be resolved by printing at a higher temperatures which will increase layer adhesion
Можно их покрыть водооталкиающим веществом.
Bro pls upload more, your channel is underrated. Imo i think it would be great if you could collab with other youtuber like rctestflight.
Hah, we want to speed up our upload schedule now :) I still can't comprehend how rctestflight makes a video every 1/2 weeks, mindblowing honestly
that was cool to see! so much work, congrats
was wondering when a new video would drop, todays a good day!
I'd love to see a CPS5 with optimised hydrodynamics now that you've tested it in Aeroshaper.
My CPS5 is so close to done, keep up the good work, lol I want the files for this drone too!
Sehr gutes Video. Gut gemacht!
I really love your videos
Man you guys are so awesome! Id love to build one of your drones
The projects done by these dudes require a lot of engineering knowledge. I appreciate it.
oh welcome back! i enjoyed chatting with y'all at OpenSauce!
Damn great video, btw for last phase of my competition the ROV I made this time is a hydrodynamic aluminium frame unlike the last time made of PVC and non hydrodynamic. It was really a challenging task to do all of this in 2 months time from designing to testing, addition of wireless communication, relative object mapping, all of this to be made ready in just 2 weeks remaining for the showdown, fingers crossed!
Good luck :)
Interesting, I though wireless was not possible under water. I have to look into this. 👀
What a great project. I like i very much. 😍
Nice work 👍
Świetny projekt!
Will you be putting out an instructional package for the Omni, like the cps5? I need to build one for inspection.
Lateral movement is difficult in any moving rc or wired build, great video
Wasz akcent brzmi tak autentycznie, że nawet nie wiedziałem że jesteście polakami zanim zabraliście tą łódź podwodną do basenu!
I love your videos, they have inspired me to build my own ROV. I cant seem to find a good propellor 3d model though and I was wondering if you guys could send the one you made.
Awesome video!! It was great to collaborate on this one :)
Thanks again for your help!
dude. awesome.
This is amazing
Dobry film chłopaki, kolejny będzie szybszy :p
I like the xdeep mask!
OmgOmgOmg!!! thats fabulous!!!
We love this!!! We can send you some domes if you want 😅😆
2:34 you can control all 6 degrees of freedom. Example with 3 motors configured as a equilateral triangle all pointed to the center, all pitched down, under gravity. In neutral buoyancy in water you need a extra motor in middle without pitching down the other three.
damn this was a great video. there's plenty of ok and even good maker vids on yt but this one flows perfectly.
I love all these underwater drones i did not know they went that "in depth"
Hello, what you did is impressive! May I ask how do you make it auto-stabilize after being hit? Isit in manual or stabilize mode of ArduSub ah?
Looking great as always.
It's a silly idea but did you guys ever thought about making a (advanced) tie fighter "shell" for this omni drone? It instantly reminded me of one hahaha. Perhaps with a more skeletal structure it would then also be more hydro dynamic. Not sure about the structural integrity thoug 😅
This is of course all just fun and giggles but I just wanted to pitch the idea anyway 😜
That's a cool idea, I remember thinking that if we'd make these PC sheets vertical next to each other instead of horizontal, it would almost look like tie fighter.
Did you use a seal on each side of the mounting holes on your dome? I was looking into this a few days back and saw someone mention that only using one sealing ring will cause ineven pressure on the camera dome and make it crack.
You can't create in a vacuum. Life gives you the material and dreams can propel new beginnings.
I love this channel, are you guys still at uni?
Yay another video
Zarąbisty dron i z jakiego miasta robicie z ciekawości
Would using vegetable oil to replace air within the sub help? Maybe not for this one but perhaps the deep diving ones. Might be a terribly idea, but I just had a thought that maybe have something other than regular air might help with the internal pressures
Filling enclosures with oil has been used for decades. We run our electronics in oil filled enclosures w/PBOF cables to help with heat dissipation and the pressures experienced at depths of 6000msw. Circulating the oil through the enclosure is easy, and you can save a lot of design time and material costs by using this method because the pressure differential is negligible compared to enclosures containing surface atmospheric pressures.
I feel like you guys are going to be the prusa printers of uuv!!
The smell test is always a necessity
In Fluid Dynamics
Thank you for calling out poor producers of essential products! it helps other builders not fall in into the pit traps that plague every project.
I fitted a tyre valve to the main tube. I can pressurise to check for leaks.
Have you guys looked into filling the electronics with oil and having a seperate bladder?
any chance on how the cfd is made? also, you guys use the paid version? or maybe student versions?
Trochę to trwało, ale warto było poczekać, że zobaczyć wasze postępy.
You mean your camera drones don't have 6 degrees of freedom but my homebuilt freestyle quad would like to have a word :D
Have you tested it in Gdansk harbor area? I wonder how much never seen crap is just chillin at the bottom
I would like to see from you an underwater fpv drone😂
Can you fill the electronic chambers with mineral oil? It could counter the pressure.
The two worst smells to detect during your dev process are ozone and magic smoke smell. We all know why the magic smoke smell is bad, but for those who don't know the ozone smell is bad because it is probably caused by electrical arcing due to a short circuit.
What if you fill the tube with mineral oil? That way it could protect everything from water damage if the tube cracks.
if we use thrust vectoring to archieve omni directional will it improve hydro dynamics by reducing number of thruster?
These are a few of my favorite smells:
Can you make a deep dive drone.!
Ale że w polsce mamy takie kanały to się nie spodziewałem😯. Świetny angielski, nie da się nawet grama polskiego akcentu zauważyć
Nice work y wish work with you group
This thing is incredible! Are you taking your battery pack out to charge it each time or do you have a BMS and charging board installed?
Also, are you running a fan in that enclosed space? I wouldn’t think that would work. It’s a struggle I’ve had!
We run our electronics in oil filled enclosures w/PBOF cables to help with heat dissipation and the pressures experienced at depths of 6000msw. Circulating the oil through the enclosure is easy, and you can save a lot of design time and material costs by using this method because the pressure differential is negligible compared to enclosures containing surface atmospheric pressures.
Super projekt
you should make one with out the cable
What about having some extra motors for forward thrust, or have the existing motors change there orientation to boost speed?
Another reason it might be slow, might be because it has 4 times the upwards thrust vs the forward.
Where were you when the titanic sank pal
Your forward thrust isn't twice is much, it's only 41% more (2 * sin(45 degrees)). It's not just about the amount of trusters, but also their angle relative to the direction of motion.
ahhh to wy z polski jesteście, dobrze po ang gadacie skapąłem sie dopiero przy próbie prędkości :D
nice
Can you scale up the old version by whatever percent and then cut holes in it? Not sure what digital software you're using
Are the Quad ESCs reversable? Did you need to reprogram them or use a different trick? I can only find ones that go in one direction only as copters usually dont go downwards with thrust.
Hey, have you considered trying to fully enclose your electronics in epoxy instead of using a canister? I do ROV design and compete, and the ROV doesn’t use any canisters, so it can save space, its also less prone to being damaged by water. Unless there are moving parts inside the canister, I don’t think it will work out. We also put the thruster ESCs on the thrusters with a 3D printed enclosure. I’m not a professional engineer so i’m sorry if this suggestion sounds bad 😅
Nice, always wanted something like this to put in an 8 inch ice fishing hole
Condensation: What about using a vacuum pump to remove all air from the boady before submerging. No moisture in a vacuum!
have u condsider hydrojet? u can manage ur submarine as a space ship with trusters just 1 engine how activate a turbine and some exaust u can fit everywere on any shape. have u consider to fill of oil or circuit? fluid are not comprimible so is more easly avoid leaking and shortcut
12:05 CCTV under water? Not sure how I'd feel about that personally!
Super
*if the core + electrics are filled with mineral oil it should be able to go far deeper without imploding as it will stop the pressure from the water*
*and stop water getting in coursing moisture and/or electrical shorts?*
now if only you could use spot welder instead on soldering lithium batteries nice drone tho
how about just two motors, differential vertical and horizontal combined in the two. like two-prop harrier with optional closing flaps. or just one motor and many flaps to direct the output thrust flow. keep it simple they said.
"You can only achieve that if your drone has side to side motion"... Alternatively that the camera is mounted perpendicular to the drones forward direction 😏
Blue Robotics also would have replaced that dome for free!
