Building a new submarine and diving to MAX DEPTH *again*

5:50 Nice. 🔥

Adding a rear camera would allow for constant monitoring of the tether which might help to avoid tangling it.

Need a mesh or netting over the propellers to prevent things from entering them.

to stop tanglement in thruster, you should try using honeycomb thruster guards. It significantly reduces tangling

Nice video! I do suggest checking the dB/dBm values on the fiber optic cable since it got stuck, it would be a shame if it lost connection on the third attempt.

Can you build a under water drone that mines the uranium? Please ☢️

The industrial design in this is phenomenal.

What an adventure, I was afraid to see this being lost but it turned well, it so amazing that the fiber optic cable still worked. As a diver I can recommend you have a secondary rescue line for the drone, usually that would be mounted on a buoy in order to see it from the surface and slow release the line to avoid being tangle, and of course have a hard long line to pull it back to the top

To avoid tangling, you can also add floating buoy to keep cable in the center and under tension.

you should add a sort of mesh tube around the fibre, to prevent it from being worn against obstacles

Thank you for giving the US distance in Furlong, could not help myself and was laughing 10 minutes straight

You should add multiple 180 degree cameras to hopefully be able to see what's happening around the drone if you end up getting tangled in places.

Thanks for showing off my CPS5 Drone in the last Video. Keep it going and to anyone else, you'll need to enter the Course because it's totally worth it.👍

So glad you got the drone back. Fingers crossed for the next go!

Panowie wielki ,wielki szacun.Emocje niesamowite tak jak praca włożona w ten projekt. Pozdrawiam serdecznie i oczywiście czekamy na część drugą 👍

Regarding the folks suggesting you oil fill the enclosure. If you want to pressure compensate, or simply pressure balance an enclosure, it's not as simple as just filling the enclosure with oil. You'll need to add a compliant bladder or spring assisted compensator to account for any air bubbles that may get trapped while oil filling. If you go the route of using a compensator, you get the added advantage that if a leak should develop, oil will leak out instead of water leaking in. If you remotely monitor your oil level, this can warn you that something is wrong and give you time to respond. What's often the most difficult challenge of oil filling enclosures is that all the components you have within the enclosure must also be pressure tolerant. Anything that's soft or contains an air space isn't suitable for an oil filled pressure housing since the oil will communicate the exterior pressure to all the components inside. This can include complex things like your camera, but also some simpler discrete components like crystal oscillators, electrolytic capacitors, and much more. component selection at the board level becomes a very important consideration when deciding whether or not to oil fill for pressure balancing or compensation. In many cases (especially when cameras are involved), it's more practical to use a one-atmosphere pressure housing.

Good job! Your close to getting to the lost river! 👻

Seems like you need to add manipulators to help move stuff out of the way...and perhaps a backup camera that can see the body of the sub.

I think you should make a redundant communication cable, so if a cable broke/snapped, you can still recover the drone

Brilliant video! Really enjoyed it. Thank you.
