@@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.
@@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
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.
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.
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. :)
Could also make an argument for using a battery with a different chemistry. Little more expensive, but there's a much more stable Lithium battery chemistry, that doesn't explode when damaged or otherwise compromised. It's also good because running it to 0 doesn't damage the battery.
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.

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.
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.
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!
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.
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
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.
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.
At 4:20, the forward thrust will not be double that of the previous model from having double motors. It will be less, as the motors are pointed away from the fwd-bck direction. Assuming a 45 degree angle, the fwd-bck thrust component from each motor will be about 0.7x of its total thrust, with a 0.7x component sideways. This will also mean that energy will be somewhat wasted when no sideways motion is desired, as some of the energy used by the four diagonal motors will be spent trying to counteract the lateral component from the other side. As long as the energy stored on the batteries is sufficent for the task at hand the sacrifice is probably worth it.
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.
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.
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.
*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?*
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!
I have a question, I'm no drones expert or something like that, so this is just by curiosity. Why didn't you just use 4 motors that can change the directions they turn independently ? Two in the left the front and back, and two in the right with same positions. When you want to sway in the left the two motors in the right turn and rotate to push the drone from the right, while the others two in the left do the stabilization. But that's just a thought.
I would want to actually see how would it work in practice. Having more thrusters is just easier because with this idea you'd still have 8 motors, but 4 to propel and 4 to turn those first 4. Also, in that scenario when you turn them to sway, you can't stabilise in other axis at the same time.
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.
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
I've seen a few UA-camrs 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
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 😅
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!

"Based on your experience, can you tell if printing 3D submarines using PLA filament is safe for long-term storage without degradation? Will PLA last for years, especially with good storage away from sunlight, heat, moisture, etc.?" Please advise
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.
iam happy to see my finished cps5 drone as picture in your video.
Thanks again for the picture!

You might want to consider spot-welding the cells in the battery instead of soldering. It's a little risky to heat them!

It's always useful to have a "SuperNose" by your side when you deal with electronics! 🤣
12:05 CCTV under water? Not sure how I'd feel about that personally!

What about having some extra motors for forward thrust, or have the existing motors change there orientation to boost speed?
was wondering when a new video would drop, todays a good day!

Thanks again for your help!
if we use thrust vectoring to archieve omni directional will it improve hydro dynamics by reducing number of thruster?
Can you scale up the old version by whatever percent and then cut holes in it? Not sure what digital software you're using
Have you guys looked into filling the electronics with oil and having a seperate bladder?
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.
